2010 Chevrolet Impala Check Engine Light Codes

The 2010 Chevrolet Impala commonly triggers codes such as P0420 (catalytic converter efficiency), P0300 (random/multiple misfires), P0113 (intake air temperature sensor), P0171 (system too lean), and P0442 (EVAP small leak). In Colorado, drivers who bring a 2010 Chevrolet Impala to Stevinson Chevrolet benefit from precise OBD-II diagnostics and transparent estimates. Each code can lead to progressive costs if ignored: an oxygen sensor left unchecked will lower fuel economy and may damage the catalytic converter, turning a $200 sensor job into a $1,000–$2,000 exhaust repair; misfires can cause piston and catalytic damage and reduce lifespan of ignition components; EVAP leaks can lead to failed emissions tests and repeated service visits. Our certified technicians use OEM test procedures and parts to restore performance and avoid repeat visits, which delivers immediate savings and better long-term value.

2010 Chevrolet Impala Check Engine Light Reset

This approach preserves warranty coverage and prevents recurring faults that cost more over time. We provide clear, itemized estimates and explain how OEM parts and certified labor deliver better longevity and fewer return visits. If cost is a concern, ask about service financing to spread payments while getting the job done now.
