Possible causes – Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2– Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 fuse– Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 harness is open or shorted– Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection– Faulty Powertrain Control Module (PCM) Tech description The code…

Possible causes – Faulty fuel injector 8– Fuel Injector 8 harness is open or shorted– Fuel injector 8 circuit poor electrical connection When is the obd code mean? If an electrical malfunction occurs in the fuel injector circuit for engine cylinder #8, the ignition feed driver signals the Powertrain Control Module (PCM) to set the…

Possible causes – Faulty fuel injector– Fuel Injector harness is open or shorted– Fuel injector circuit poor electrical connection When is the obd code mean? If the Powertrain Control Module (PCM) detects an incorrect voltage for the commanded state of the driver, a fuel injector control code will set. Symptoms – Engine Light ON (or…

Possible causes – Faulty Fuel Level Gauge– Fuel Level Gauge harness is open or shorted– Fuel Level Gauge circuit poor electrical connection– Faulty Powertrain Control Module (PCM) When is the obd code mean? If the fault detection circuit senses a voltage other than what the PCM expects, the fault line status changes causing the P0656…

Possible causes – Faulty fuel level sensor– Fuel level sensor harness is open or shorted– Fuel level sensor circuit poor electrical connection Tech description Low fuel level can trigger this code. Before replacing any parts try filling up the fuel tank and erasing the engine code. If the problem persist it may be necessary to…

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

Possible causes – Faulty fuel injector 1– Fuel Injector 1 harness is open or shorted– Fuel injector 1 circuit poor electrical connection When is the obd code mean? If an electrical malfunction occurs in the fuel injector circuit for engine cylinder #1, the ignition feed driver signals the Powertrain Control Module (PCM) to set the…

Possible causes – Faulty fuel injector 2– Fuel Injector 2 harness is open or shorted– Fuel injector 2 circuit poor electrical connection When is the obd code mean? If an electrical malfunction occurs in the fuel injector circuit for engine cylinder #2, the ignition feed driver signals the Powertrain Control Module (PCM) to set the…

Possible causes – Faulty fuel injector 3– Fuel Injector 3 harness is open or shorted– Fuel injector 3 circuit poor electrical connection When is the obd code mean? If an electrical malfunction occurs in the fuel injector circuit for engine cylinder #3, the ignition feed driver signals the Powertrain Control Module (PCM) to set the…
