DTC P062D Fuel Injector Driver Circuit Performance Bank1

DTC P062E Fuel Injector Driver Circuit Performance Bank2


DESCRIPTION

The EDU delivers drive signals to fuel injectors using the DC/DC converter, which provides a high-voltage and quick-charging system.
Soon after the EDU receives a fuel injection command (#1 to #8) signal from the ECM, the EDU responds to the command with an injector injection confirmation (INJF) signal when the current is applied to the injector assembly.

MONITOR DESCRIPTION

  1. P062D, P062E (Open or short in EDU or injector assembly circuit):
    The ECM continuously monitors both injection command (#1 to #8) signals and injection confirmation (INJF) signals. This DTC will be stored if the ECM determines that the number of #1 to #8 signals and INJF signals are inconsistent.
    The fuel injectors are grounded over a Field Effect Transistor (FET) and a serial resistor. This resistor creates a voltage drop, which is monitored by the EDU (injector drive circuit) in relation to the current drawn by the injector assembly. When the injector assembly current becomes too high, the voltage drop over the resistor exceeds a specified level and no INJF signal for that cylinder is sent to the ECM.
    After the engine is started, when there is no injection confirmation (INJF) signal from the No. 1 or No. 2 EDU to the ECM even though the ECM sends injection command (#1 to #8) signals to the No. 1 or No. 2 EDU, DTC P062D or DTC P062E is stored.
    If this DTC is stored, the ECM enters fail-safe mode and limits engine power or stops the engine. The fail-safe mode continues until the ignition switch is turned off.

INSPECTION PROCEDURE

NOTICE:
  1. After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
  2. After replacing a fuel injector, the ECM needs registration (Click here).
HINT:
Read freeze frame data using the GTS. Freeze frame data records the engine condition 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, and other data from the time the malfunction occurred.
1.CHECK TERMINAL VOLTAGE EDU POWER SOURCE

  1. Disconnect the No. 1 injector driver (EDU) connectors.
