Error codes P2076 and P0420

10

Asked by Jun 06, 2017 at 12:56 AM about the 2012 Chevrolet Sonic

Question type: Maintenance & Repair

I have both error codes and I was wondering if the
same thing could cause both issues?  If so how
much would it likely cost to repair.

Possibly, but there is no code related to Chevy p2076. The po420 has to do with the catalytic converters....Possible causes: Three way catalyst converter Bank 1, Exhaust tube, Intake air leaks, Fuel injectors may be faulty, Fuel injector leaks, Spark plugs may be faulty, Improper ignition timing, Powertrain Control Module (PCM)...As the code description implies the P0420 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0420 code is combined with other codes, try fixing the other codes first.
