2019 Chevrolet Tahoe Check Engine Light Codes
The 2019 Chevrolet Tahoe commonly reports codes such as P0420 (catalyst efficiency), P0171 (system too lean), P0300 (random/multiple misfires), and P0455 (large EVAP leak). Ignoring these codes can lead to escalating costs: a failing catalytic converter (P0420) can become permanently damaged and cost $1,000–$2,500 to replace, lean conditions (P0171) can reduce fuel economy and cause performance issues, misfires (P0300) can damage the catalytic converter and lead to engine harm, and EVAP leaks (P0455) may cause failed emissions tests and decreased fuel efficiency. At Herb Chambers Chevrolet in MA we diagnose codes precisely with OEM tools to avoid unnecessary repairs and to spot related issues early. Our factory-trained technicians prioritize fixes that deliver immediate savings—accurate repairs reduce repeat visits—and long-term value by preserving drivetrain life.
