Possible causes – Air leak between the MAF sensor and throttle body– Dirty Throttle body or Mass Air Flow (MAF) sensor– Throttle Position (TP) sensor not seated properly– Faulty Throttle Position (TP) sensor– Faulty Mass Air Flow (MAF) sensor When is the obd code mean? If the PCM detects that the difference between the actual…

Possible causes – AIR relay fault – stuck closed– Secondary AIR pump fault – circuit open in motor– Open ground to secondary AIR pump– Open AIR monitor circuit between the secondary AIR pump and the PCM– Short to voltage in the AIR relay to secondary AIR pump voltage circuit Symptoms – Engine Light ON (or…

Possible causes – Battery charge– Faulty Generator– Generator harness is open or shorted– Generator circuit poor electrical connection– Engine Control Module (ECM) controlled generator– Faulty ECM Tech description The ECM is detecting a high turn-on voltage at times. Possible causes could be the alternator or the ECM. When is the obd code mean? The Engine…

Possible causes – Battery charge– Faulty Generator– Generator harness is open or shorted– Generator circuit poor electrical connection– Engine Control Module (ECM) controlled generator– Faulty ECM When is the obd code mean? The Engine Control Module (ECM) has fault detection circuitry which monitors the state of the generator turn on signal circuit. If the fault…
