PCM...Code P0420
 

Got a "check engine light".... 1/2 hour after I got the car inspected, lucky it didn't happen on the way to the inspection station.

Looked up the code and it says,"System Low Efficiency Bank 1"
Does this mean my car is getting as tired as I am?
Car only has 188,600 miles on it.
Thanks

You better take it to the doctor.
The Vette Doctor that is :D
& bring soup

:iagree:

P0420 is a catalyst system code. Bank 1 is the driver side. The PCM compares the readings between the front O2 sensor (forward of the catalytic converter) and the rear sensor (after the cat). If it doesn't see much difference... "low efficiency." It could be just an exhaust leak, but with 188.6K on the odometer, it's probably a failed converter.

Bobby, you started an epidemic....have Carmen shut off the back 02's :thumbs:

By the way, long time no hear. How is everything....good we hope. This are cool here, getting ready for Krissy's big day.

See ya soon
