Possible causes – Low transmission fluid level– Dirty transmission fluid– Faulty shifting solenoid valve– Shifting solenoid valve harness is open or shorted– Shifting solenoid valve circuit poor electrical connection When is the obd code mean? The P0785 code is detected when the PCM detects a continuous open, short to ground or short to power in…

Possible causes – Low transmission fluid level– Dirty transmission fluid– Faulty solenoid valve– Shift Solenoid valve harness or connectors– Shift Solenoid valve circuit is open or shorted Tech description When the a transmission solenoid is stuck on, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material…

Possible causes – Leaking injector or regulator– Engine ignition misfire– Engine mechanical condition– Faulty HO2S– HO2S Sensor 2 harness is open or shorted– HO2S Sensor 2 circuit poor electrical connection Symptoms – Engine Light ON (or Service Engine Soon Warning Light)

Possible causes – Leaking or stuck open thermostat– Low engine coolant level– Insufficient warm up time– Faulty engine coolant temperature sensor– Engine coolant temperature sensor harness is open or shorted– Engine coolant temperature sensor circuit poor electrical connection Tech description If cooling system is not leaking and the fluid level is OK, replacing the thermostat…

Possible causes – Loose or poor battery terminal connection– Low battery charge– ECM power supply circuit is open or shorted– ECM Programing– Faulty ECM Tech description Check the ECM fuse, if fuse is OK try erasing the code first and if the code comes back you may have to reprogram or replaced the ECM. When…

Possible causes – Loose or poor battery terminal connection– Low battery charge– ECM power supply circuit is open or shorted– ECM Programing– Faulty ECM Tech description Start by charging the vehicles battery and clean terminal, once the battery is charged and the terminals are clean and secure, erase code. If the code comes back ON…

Possible causes – Low battery charge– Battery defective– Loose or missing alternator drive belt– Faulty alternator– Open or short system voltage circuit Tech description Start by recharging or replacing the battery. When is the obd code mean? The Engine Control Module (ECM) has detected that the electrical system voltage level is out of range. Symptoms…

Possible causes – Low engine coolant level– Faulty Engine Coolant Temperature (ECT) sensor– Faulty engine coolant thermostat– Engine Coolant Temperature (ECT) sensor harness is open or shorted– Engine Coolant Temperature (ECT) sensor circuit poor electrical connection When is the obd code mean? An excessively low voltage from the sensor is sent to ECM. Symptoms –…
