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 –…

Possible causes – Faulty Vacuum Switching Valve (VSV)– Vacuum Switching Valve (VSV) harness is open or shorted– Vacuum Switching Valve (VSV) circuit poor electrical connection– Faulty Pressure Sensor– Faulty Air Switching Valve When is the obd code mean? If the Engine Control Module (ECM) receives the pulsation signal from the sensor despite the ECM ordering…

Possible causes – Faulty Vehicle Speed Sensor– Vehicle Speed Sensor harness is open or shorted– Vehicle Speed Sensor circuit poor electrical connection When is the obd code mean? If the fault detection circuit senses a voltage other than what is expected, the fault line status changes causing the P0608 to set. Symptoms – Engine Light…

Possible causes – Faulty Vehicle Speed Sensor– Vehicle speed sensor harness or connectors is open or shorted– Vehicle speed sensor circuit poor electrical connection– Faulty Engine Control Module (ECM) When is the obd code mean? The almost 0 km/h (0 MPH) signal from vehicle speed sensor is sent to ECM even when vehicle is being…

Possible causes – Fuel system leakage– Faulty fuel injector– Faulty Fuel Rail Pressure (FRP) sensor– Fualty Fuel Pump Symptoms – Engine Light ON (or Service Engine Soon Warning Light) ISUZU Related P1093 code 2004 ISUZU HTR Engine And Engine Cooling:engine:diesel 2004 ISUZU HVR Engine And Engine Cooling:engine:diesel 2004 ISUZU HXR Engine And Engine Cooling:engine:diesel 2005…

Possible causes – Fuel Tank Pressure Sensor– Fuel Tank Pressure sensor harness is open or shorted– Fuel Tank Pressure sensor circuit poor electrical connection– Faulty Engine Control Module (ECM) When is the obd code mean? A intermittent voltage signal from the fuel tank pressure sensor is sent to Engine Control Module (ECM). Symptoms – Engine…
