2023 Chevrolet Tahoe Check Engine Light Codes

At Herb Chambers Chevrolet in MA, we see a range of common check engine codes on the 2023 Chevrolet Tahoe — P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0171/P0174 (fuel trim lean conditions), and P0135/P0138 (oxygen sensor heater circuit). Left unaddressed, these codes can lead to reduced fuel economy, failed emissions tests, increased repair bills (a faulty catalytic converter can cost thousands to replace if not caught early), and potential engine damage. Our certified technicians use factory-grade scanners to pinpoint whether the issue is a sensor, wiring, fuel delivery, or exhaust component. This diagnostic precision prevents unnecessary part replacements and saves money over time.

2023 Chevrolet Tahoe Check Engine Light Reset

Our technicians document codes, perform the necessary repairs using OEM parts, and confirm repairs with a road test and final scan — preserving warranties and ensuring longevity. Dealership service provides transparency: you get itemized estimates, technician reports, and genuine Chevrolet parts backed by factory warranties. This approach often delivers better value than one-off resets at independent shops because it reduces the chance of repeat visits and prevents progressive damage.
