Possible causes – Intermittent gear ratio problems– Internal transmission problems When is the obd code mean? The P0792 code is detected if there is an excessive change in the output rpm in any gear. Symptoms – Engine Light ON (or Service Engine Soon Warning Light)

Possible causes – Large vacuum leak on the engine – Faulty Manifold Pressure (MAP) sensor – Faulty Throttle Position Sensor (TPS)– Faulty Engine Control Module (ECM) Symptoms – Engine Light ON (or Service Engine Soon Warning Light) P2074 JEEP OBD Code Description The Engine Control Module (ECM) has detected a failed signal correlation between the…

Possible causes – Leak Detection Pump (LDP) harness is open or shorted – Leak Detection Pump (LDP) poor electrical connection – Faulty Leak Detection Pump (LDP) When is the obd code mean? Malfunction is detected when the Powertrain Control Module (PCM) detected the leak detection pump switch did not change after the solenoid was energized…
