Common codes for the 2021 Jeep Wrangler often include oxygen sensor faults (P0130–P0155 range), misfire codes (P0300–P0306), and EVAP system errors (P0440–P0455). Each code has cost implications: leaving an oxygen sensor fault untreated reduces fuel economy and can lead to catalytic converter failure, which is significantly more expensive than the initial sensor repair. Misfires left unresolved can damage the catalytic converter and increase engine wear, escalating repair bills. EVAP leaks can cause failed emissions tests and affect drivability. At Larry H.
