General Information

Component Location





General Description

Based on information from various sensors, the PCM measures the fuel injection amount. The fuel injector is a solenoid-operated valve and the fuel injection amount is controlled by length of time the fuel injector is held open. The PCM controls each injector by grounding the control circuit. When the PCM energizes the injector by grounding the control circuit, the circuit voltage should be low (theoretically 0V) and the fuel is injected. When the PCM de-energizes the injector by opening the control circuit, the fuel injector is closed and circuit voltage should momentarily peak.

DTC Description

Checking output signals from injectors. under detecting condition, if an output signal is high. PCM sets P0262. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle
