Possible causes – The vehicle is new from the factory.– Battery or Powertrain Control Module (PCM) had recently been disconnected.– An OBD monitor failure occurred before completion of an OBD drive cycle.– PCM Detected Trouble Codes (DTC) have recently been cleared with a scan tool. Tech description This code just means that the PCM didn’t…

Possible causes – Low transmission fluid level– Dirty transmission fluid– Shift solenoids– Transmission mechanical problems– Transmission hydraulic control circuit Tech description Start by inspecting the transmission fluid level and condition, and change fluid if necessary. When is the obd code mean? P0733 is detected when A/T cannot be shifted to the 3rd gear position even…

Possible causes – Low transmission fluid level– Dirty transmission fluid– Shift solenoids– Transmission mechanical problems– Transmission hydraulic control circuit Tech description Start by inspecting the transmission fluid level and condition, and change fluid if necessary. When is the obd code mean? P0734 is detected when A/T cannot be shifted to the 4th gear position even…

Possible causes – Low transmission fluid level– Dirty transmission fluid– Shift solenoids– Transmission mechanical problems– Transmission hydraulic control circuit Tech description Start by inspecting the transmission fluid level and condition, and change fluid if necessary. When is the obd code mean? P0735 is detected when A/T cannot be shifted to the 5th gear position even…

Possible causes – Faulty Crankshaft Position (CKP) Sensor– Crankshaft Position (CKP) Sensor harness is open or shorted– Crankshaft Position (CKP) Sensor circuit poor electrical connection– Communication error between the Engine Control Module (ECM) and Transmission Control Module (TCM) When is the obd code mean? The P0727 Codes is triggered when the TCM receives no signal…

Possible causes – Faulty Engine Control Module (ECM)– ECM harness is open or shorted– ECM circuit poor electrical connection– ECM Programming When is the obd code mean? The Engine Control Module (ECM) has detected a high voltage to the transmission control solenoids. Symptoms – Engine Light ON (or Service Engine Soon Warning Light)

Possible causes – Faulty Gear Position Switch– Misadjusted Gear Position Switch– Gear Position Switch harness is open or shorted– Gear Position Switch circuit poor electrical connection When is the obd code mean? The transmission Gear Position Switch detects the selector lever position and sends a signal to the TCM. Symptoms – Engine Light ON (or…

Possible causes – Faulty Manifold Absolute Pressure sensor– Manifold Absolute Pressure harness is open or shorted– Manifold Absolute Pressure sensor circuit poor electrical connection– Faulty Engine Control Module (ECM) When is the obd code mean? An excessively low or high voltage from the sensor is sent to ECM. Symptoms – Engine Light ON (or Service…

Possible causes – Faulty mass air flow sensor– Intake air leaks– Dirty mass air flow sensor– Dirty mass air filter– Mass air flow sensor harness is open or shorted– Mass air flow sensor circuit poor electrical connection Tech description Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air…
