-> No GO to Pinpoint Test G552275t57.
G552275t52 : CHECK THE FUEL INJECTOR CIRCUIT FOR HIGH RESISTANCE 1. Disconnect the fuel injector 2 (INJ2) connector, C46. 2. Measure the resistance between: C46, harness side C101, harness side Pin 02
Pin M2
Pin 01
Pin L2
Are the resistances less than 10 ohms? -> Yes An intermittent fault may be present in the wiring harness. Visually check for chaffed wires or other physical damage to the harness. If no fault is found in the circuit, suspect the following component(s): - Fuel injector 2 (INJ2) connector - ECM connector - Fuel injector 2 (INJ2)
-> No REPAIR the high-resistance. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation. G552275t53 : CHECK THE FUEL INJECTOR CIRCUIT FOR SHORT CIRCUIT TO 1. Key on, engine off. 2. Measure the resistance between: C101, harness side Battery

Negative terminal Pin L2
Negative terminal
Are the resistances greater than 100 Kohms? -> Yes GO to Pinpoint Test G552275t55.
