2021 Chevrolet Spark Check Engine Light Codes

Common check engine light codes for the 2021 Chevrolet Spark often include P0420 (catalytic converter efficiency), P013X (oxygen sensor), and P030X (multi-cylinder misfire). Left unaddressed, a P0420 can lead to higher emissions fines, reduced fuel economy, and eventual converter failure—replacement costs can rise significantly. Oxygen sensor codes (P013X) usually worsen fuel trims and fuel consumption if delayed, and misfire codes (P030X) can damage pistons and the catalytic converter. At Herb Chambers Chevrolet in MA, our technicians prioritize root-cause resolution: we pair advanced diagnostics with OEM parts to correct the underlying issue and preserve performance. Choosing us means faster turnaround, clear estimates, and the confidence of factory-trained technicians who understand the 1.4L inline engine in your 2021 Chevrolet Spark.
