READ VALUE USING INTELLIGENT TESTER (INJECTION FEEDBACK VAL #1 to #4)Ĭonnect the intelligent tester to the DLC3. REPAIR OR REPLACE HARNESS OR CONNECTOR Click hereĬONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED Click here The fail-safe mode continues until the ignition switch is turned off.Ĭ60-8 (INJF) or C69-51 (INJF) - Body ground If this DTC is stored, the ECM enters fail-safe mode and limits engine power or stops the engine. When the fuel injector current becomes too high, the voltage drop over the resistor exceeds a specified level and no IJF signal for that cylinder is sent to the ECM.Īfter the engine is started, when there is no injection confirmation (IJF) signal from the EDU to the ECM even though the ECM sends injection command (IJT) signals to the EDU, DTC P062D is stored. This resistor creates a voltage drop, which is monitored by the EDU (injector drive circuit) in relation to the current drawn by the fuel injector. The fuel injectors are grounded over a Field Effect Transistor (FET) and a serial resistor. This DTC will be stored if the ECM determines that the number of IJT signals and IJF signals are inconsistent. The ECM continuously monitors both injection command (IJT) signals and injection confirmation (IJF) signals. MONITOR DESCRIPTION P062D (Open or short in EDU or fuel injector circuit):
