Catalytic Converter Replacement And Diagnosis
Repairs For Clogged And Leaking Exhaust Systems And Catalytic Converters
Hendersonville Muffler and Brakes repairs exhaust systems in cars and trucks in the Hendersonville, Tennessee area. We diagnose and replace Catalytic converters and clogged and leaking exhaust systems regularly. Modern cars and trucks have electronic control modules that monitor the Catalytic converter for proper operation and report the findings back to the ECM. The ECM commonly will alert the customer by throwing code PO420 which is a catylist efficiency code.
Don't Let The Auto Parts Store Diagnose Your Problems
Many of our clients go to the auto parts stores before they bring their car or truck to us. Code PO420 is a catylist efficiency code caused by the second oxygen sensor not reading enough of a change after the Catalytic converter. Many of our customers purchase the post catylist oxygen sensor from the auto parts store. It is very common to have the auto parts store tell you that the reason the light came on is because the oxygen sensor after the Catalytic converter is lying to the ECM. This is the case in less than 5% of all PO420 code problems. It is also very easy to test to see if the oxygen sensor is really working. It has been our experience that anyone who really understands how modern ECM/ PCM systems in cars and trucks function is working on cars and not at an auto parts store.
We have known good oxygen sensors we can temporarily install to compare. We have sensor simulators to see what the vehicle will do with a good sensor reading. We see many technicians in other shops in the area trying all sorts of different cures that all have one thing in common. They WILL NEVER CURE YOUR PROBLEM. Joe the owner of Hendersonville Muffler and Brakes will tell them "You almost got it this time, keep chasing it an you're sure to catch your tail real soon but you never going to cure the car that way
