-> No GO to Pinpoint Test G290117t12.
G290117t12 : CHECK THE INJECTOR SUPPLY VOLTAGE 1. Turn the ignition switch to the ON position. 2. Disconnect the relevant injector harness electrical connector (PI32 to PI39). 3. Measure the voltage between the relevant injector harness electrical connector (PI32 to PI39) pin 02 and GROUND. Is the voltage less than 10 Volts? -> Yes REPAIR the circuit between the relevant injector harness electrical connector (PI32 to PI39) pin 02 and battery. This circuit includes the front power distribution fuse box, fuse 13, and the EMS control relay. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

G290117t13 : CHECK THE INJECTOR GROUND CIRCUIT 1. Turn the ignition switch to the OFF position. 2. Disconnect the battery negative terminal. 3. Disconnect the ECM electrical connector PI01. 4. Measure the resistance between the relevant injector harness electrical connector (PI32 to PI39) pin 001 and the ECM electrical connector PI01, pins as follows: Injector Cyl 1, PI32 pin 01 (BG) and PI01 pin 120 (BG). Injector Cyl 2, PI36 pin 01 (BR) and PI01 pin 115 (BR). Injector Cyl 3, PI33 pin 01 (BK) and PI01 pin 114 (BK). Injector Cyl 4, PI37 pin 01 (BO) and PI01 pin 119 (BO). Injector Cyl 5, PI34 pin 01 (BG) and PI01 pin 113 (BG). Injector Cyl 6, PI38 pin 01 (U) and PI01 pin 118 (U). Injector Cyl 7, PI35 pin 01 (BW) and PI01 pin 117 (BW). Injector Cyl 8, PI39 pin 01 (UY) and PI01 pin 112 (UY). Is the resistance greater than 5 ohms? -> Yes REPAIR the circuit between the relevant injector harness electrical connector pin 01 and the engine |
