A check engine code scan in South Windsor is the starting point, not the answer. Codes like P0420, P0300, or P0171 describe what the engine computer noticed, not which part caused it. Our check engine diagnostic process scans every module, reviews freeze-frame data from the moment the code set, then tests the specific sensor, circuit, or system involved. That can include smoke testing for EVAP and vacuum leaks or checking sensor signals with a scope. When we finish, you get the cause, the repair, and the price.
