2025 Chevrolet Silverado 1500 Check Engine Light Codes
Common check engine codes for the 2025 Chevrolet Silverado 1500 include P0420 (catalyst efficiency), P0300–P0304 (random/individual cylinder misfires), P0171 (system too lean), and P0455 (large EVAP leak). Each code has implications if left untreated: a P0420 left unresolved can mean a failing catalytic converter and possible emissions test failure with replacement costs running into the thousands; misfire codes (P0300 series) can cause poor fuel economy, rough running, and long-term engine damage if ignored; a P0171 can indicate fuel delivery or vacuum issues that reduce fuel efficiency; an EVAP leak like P0455 can cause check engine lights and emissions problems.
