13 best catalytic converter tests

Catalytic converter tests are procedures used to assess the functionality and efficiency of catalytic converters in automotive exhaust systems. These tests are essential for ensuring that vehicles meet emissions standards and are environmentally friendly. Here are some key aspects of catalytic converter tests:

  1. Emissions Testing: Emissions testing is a crucial part of catalytic converter assessment. This involves measuring the exhaust gases from a vehicle's tailpipe to determine if it complies with local and national emissions standards. Common pollutants measured include carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx).

  2. Visual Inspection: In some cases, a visual inspection of the catalytic converter may be conducted to check for physical damage or signs of tampering.A damaged converter may not function effectively.

  3. On-Board Diagnostics (OBD): Modern vehicles are equipped with onboard diagnostics systems that can detect catalytic converter issues. These systems may trigger a "check engine" light if there's a problem with the converter or emissions control system.

  4. Tailpipe Emission Analysis: This test involves sampling the exhaust gases directly from the tailpipe of a running vehicle. The emissions are then analyzed to determine the levels of various pollutants, which can indicate how well the catalytic converter is functioning.

  5. Plug-in Diagnostic Tools: Mechanics and technicians can use diagnostic tools that plug into a vehicle's OBD port to read fault codes and data related to the catalytic converter. This information can help identify issues with the converter.

  6. Dynamometer Testing: Some testing facilities use dynamometers to simulate different driving conditions, allowing for more comprehensive testing of catalytic converters under various load and speed conditions.

  7. Exhaust Gas Temperature Measurement: High exhaust gas temperatures can indicate a malfunctioning catalytic converter. Technicians can measure these temperatures at various points in the exhaust system to diagnose problems.

  8. Replacement and Repair: If a catalytic converter fails testing or is found to be faulty, it may need to be replaced. In some cases, minor repairs, such as welding, can be done to fix small issues.

  9. Legal Requirements: Catalytic converter tests are essential for ensuring that vehicles comply with emissions regulations. Failure to meet these standards can result in fines, vehicle impoundment, or the inability to renew vehicle registration.

  10. Environmental Impact: Properly functioning catalytic converters play a significant role in reducing harmful emissions that contribute to air pollution and climate change. Ensuring their functionality through testing is crucial for environmental protection.

In conclusion, catalytic converter tests are essential for verifying that vehicles meet emissions standards, reduce harmful pollutants, and operate efficiently. Regular testing and maintenance of catalytic converters are necessary to ensure vehicle performance and environmental responsibility.

User questions & answers

Question: Is this for the passenger side
Answer: i've done it 4 days before testing...and this is if you're failing due to a worn out cat converter; if you're not passing due to HC, that is a tune up and maybe new O2 sensor...
Question: Is this for the passenger side of a 2008 Infiniti g
Answer: Yes, it will. The "rotten egg" smell is unburned fuel passing through your car due to dirty injectors, dirty intake valves, dirty compression chambers, dirty catalytic converts and dirty EGR valve & passageways, and dirty spark plug tips. This product cleans all of these areas.
Question: Is this for the sedan and coupe g
Answer: I have a 2001 toyota sequoia & both my 0420 & 0430 (driv/passen) was failing, ive tried red line($18), cataclean($28) & seafoam($14), all 3 worked after 50-60 miles, but after 100-150 miles check engine light came back on reading the same 2 codes. BUT G2P 20 miles after adding check eng light turned off & 100 miles later its still off (cross my fingers) i was so happy with its speedy results Z& its price, im buying 5-6 at a time & using it like a gas additive with chevron gasoline. i dont have to smog for 10 months but driver catalytic cost $2320 & passen cat cost &2160, either 1 almost surpassing bluebook value, ....i feel like i cant lose running 1 a month in my ride @ least until its time to register
Question: Does this converter fit a 2008 G37 coupe
Answer: I once submitted all the required paperwork for the money back and they never sent me a dime. I did see slight lowering of some numbers but very little. Basically buy it but don’t expect to actually get a refund much less twice the amount

User questions & answers

Question: So my catalytic converter was stolen (sawed off) and it says this fits on a toyota camry 2004 le v4 but on the notes it says rear what does that mean
Answer: yes
Question: Does this work for a 2004 honda insight cvt
Answer: This is to check for clogged catalytic converter not worried you're going to use it for using that gauge Zack
Question: Will it fit honda crv
Answer: If you have this type of O2 sensor: http://www.amazon.com/gp/product/B002Q94CLG?*Version*=1&*entries*=0you need to do one of three things to get the back pressure gage attached. 1.) get an old O2 sensor and drill, grind, cut off the guts so that all that remains is the flat plate with two bolt holes,..thread the large center hole (that the guts were removed from) to allow the large standard gage adapter to screw into. 2.) Remove the O2 sensor and determine if the large center hole in the exhaust can be drilled/threaded to fit one of the adapters that came with gage.3.) Measure the male threads (dia. and thread pitch) on the smallest adapter and drill a hole in exh. pipe in a conveniant place before the cat converter and use a tap to thread the hole for the fitting. When done testing,..get a brass plug that is the same thread as the hole you just drilled and tapped. There are also fittings out there that are meant specifically to do this exact thing but have not bothered looking for them. As far as the gage being stuck on 1.5 psi,..it's either defective or it was dropped or too much pressure was hooked to it or it was left connected to hot exhaust for too long. They are meant to take a quick reading for diagnostic purposes only and then disconnected. You should be able to blow in the hose with a strong breath of air and get the gage to go up,..if so just subtract 1.5 psi from the reading to get an accurate number. A good free flowing exhaust will be less than 2 to 2.5 psi at 2500 rpm.
Question: my car is slow on the hills no power and i am already change the turbo and still slow and somebody told me tha i need this part can it be for sure
Answer: It will work on any vehicle that has oxygen sensors. The fittings are all included.

About Check Engine Light On

  • Most vehicle owners care about if this catalytic converter can eliminate the check engine light on caused by code P0420 - catalyst system efficiency below threshold.
  • We would answer definitely YES! But before replacing a catalytic converter, please make sure your O2 sensors still work well. Faulty sensors can cause damage to spark plugs, catalytic converters and damage your fuel economy.

Replacement Guide (Do It Yourself)

  • Raise the vehicle and secure it on jack stands.
  • Identify the catalytic converter on the underside of the vehicle.
  • Remove the oxygen sensors.
  • Spray penetrating oil on the exhaust flange hardware and flanges, then remove the Old Catalytic Converter.
  • Install new catalytic converter, direct bolts to existing exhaust system - Do not forget to install gaskets to prevent exhaust leaks.

High Flow Cats Increase Power

  • The problem with regular catalytic converters is that they don’t always allow the gasses to pass through as efficiently as possible.
  • High flow catalytic converters allow for the more efficient flow of exhaust gasses, removing restrictions that can impede performance.
  • If the original OE converter does not match your engine power, a high flow cat might be a great choice.

WALKER CATALYTIC CONVERTERS

Walker offers catalytic converters manufactured with a stainless-steel body, aluminized pipe and heat shields, that provide you peace-of-mind with assured compliance by engineers who set the standard. Whether it’s universal or direct-fit, catalytic converters feature an optimal high-technology washcoat and OE-design precious metal load that deliver required reduction in tailpipe emissions to match vehicle application.

FIVE CHECKS BEFORE REPLACING A CATALYTIC CONVERTER

Converters don’t fail on their own, complete these five checks before replacing a catalytic converter:

  1. Retrieve / repair all PCM trouble codes, check for any available TSBs or PCM re-flash updates
  2. Repair all exhaust leaks
  3. Make sure vehicle is in proper fuel control
  4. Always check for internal coolant leaks and excessive oil consumption
  5. Make sure you have the right part for the application

WHY A CATALYTIC CONVERTER FAILS

Converters don’t fail on their own; failure is usually a symptom of a larger problem. This is why it is important to identify the root cause of the failure and perform the repair prior to installing a new converter. Most catalytic converter failures fall under one of three categories:

  • Overheated, melted or broken converters
  • Coated/oil-fouled substrate
  • Structural damage

DIRECT-FIT VS. UNIVERSAL CONVERTERS

Walker universal fit catalytic converters have a customizable design with expandable bushings to adapt to connector pipes based on the repair. They may require specialized fabrication and welding for installation. Walker pre-bent routings hangers and flanges for OE-style direct-fit catalytic converters attach to the exhaust system for a direct-fit bolt-off, bolt-on solution. No matter what you select, all converters must meet the emission requirements of the vehicle and cannot be chosen by size alone.

WHAT TO DO IF CHECK ENGINE LIGHT COMES ON?

Troubleshoot an illuminated check engine light by making sure the gas and oil caps are on tight and that the oil dipstick is seated correctly. If the light remains lit, it could be triggered by a faulty oxygen sensor, failing catalytic converter, bad spark plugs, malfunctioning thermostat or bad mass air flow sensor.

WHAT IS THE DIFFERENCE BETWEEN EPA AND CARB CONVERTERS

EPA-compliant catalytic converters are for use on EPA or Federal emissions certified-vehicles. EPA-compliant catalytic converters cannot be sold or installed in California and Colorado and in certain circumstances in Maine and New York. In those states, you must install a CARB-compliant catalytic converter on CARB emissions certified vehicles in the states of California and Colorado, on all vehicles. CARB-compliant converters contain more catalyst material in order to converter emissions more efficiently and comply with stricter emissions reduction requirements. Check the vehicle’s emissions control information label and consult your state’s aftermarket converter regulations to select the right catalytic converter.

About Check Engine Light On

  • Most vehicle owners care about if this catalytic converter can eliminate the check engine light on caused by code P0420 - catalyst system efficiency below threshold.
  • We would answer definitely YES! But before replacing a catalytic converter, please make sure your O2 sensors still work well. Faulty sensors can cause damage to spark plugs, catalytic converters and damage your fuel economy.

Replacement Guide (Do It Yourself)

  • Raise the vehicle and secure it on jack stands.
  • Identify the catalytic converter on the underside of the vehicle.
  • Remove the oxygen sensors.
  • Spray penetrating oil on the exhaust flange hardware and flanges, then remove the Old Catalytic Converter.
  • Install new catalytic converter, direct bolts to existing exhaust system - Do not forget to install gaskets to prevent exhaust leaks.

High Flow Cats Increase Power

  • The problem with regular catalytic converters is that they don’t always allow the gasses to pass through as efficiently as possible.
  • High flow catalytic converters allow for the more efficient flow of exhaust gasses, removing restrictions that can impede performance.
  • If the original OE converter does not match your engine power, a high flow cat might be a great choice.
