DESCRIPTION

DTC Detection Conditions:

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

The high speed activation of the high pressure fuel injector is possible through the high-voltage, rapid-recharge DC/DC converter. Using high pressure fuel, the atomized fuel's injection timing can be accurately controlled, which decreases emissions and fuel consumption. The steady ECM checks the injector driver movement. When the injector driver or inject has a malfunction, the injection control of the relevant cylinder is stopped or power to the injector relay is cut. Then the ECM illuminates the check engine warning light.

INSPECTION PROCEDURE

HINT: Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
