Do you need a catalytic converter?
Yes, every passenger vehicle sold in the past 35 years is required to have a “cat” – the catalytic converter used in the exhaust system to reduce harmful emissions and allow the vehicle to pass mandatory smog tests.
What does catalytic converter warning light look like?
The image, which looks like flames or wavy lines rising from a pipe, indicates an overheated, damaged or malfunctioning catalytic converter. The converter is vital to the proper operation of the engine, so some vehicles may reduce the engine’s power automatically. And of course, it will be very hot.
What does check engine light mean on catalytic converter?
The check engine light will come on if it’s below this threshold, determined by oxygen sensors that are located before and after the catalytic converter. The sensors will trigger an Onboard Diagnostics (OBD) trouble code that’s stored in your car’s computer. OBD Code P0420 means the catalyst system efficiency is below the threshold.
When does the camshaft position sensor need to be replaced?
If you have any of these symptoms, it could mean the camshaft position sensor needs to be replaced by a professional mechanic as soon as possible. It needs to be completed before the engine cuts out and dies while you are driving, or does not start at all. 2. Check Engine Light comes on
What happens if you replace the catalytic converter?
If you spend $900 or more to replace the catalytic converter, you may discover the check engine light coming on again later. Some mechanics will tell you to try replacing the oxygen sensors first, to see if that solves the problem. There are two of them, one before and one after the catalytic converter.
What kind of test should I do on my catalytic converter?
That’s necessary to detect catalyst efficiency accurately. A good mechanic might test by using a scope to diagnose the oxygen sensors or do a vacuum test or backpressure test, and just charge you a fee for the diagnostic service so that you can decide what you want to do as far as repairs are concerned. So what do you do?
