Is the resistance greater than 100 Kohms? -> Yes GO to Pinpoint Test G552286t24.
-> No REPAIR the short circuit. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation. G552286t24 : CHECK THE DPF TEMPERATURE SENSOR SIGNAL CIRCUIT FOR 1. Disconnect the ECM connector, C101. 2. Measure the resistance between: GB10, harness side C101, harness side Pin 01

Is the resistance less than 10 ohms? -> Yes GO to Pinpoint Test G552286t25.
-> No REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. Clear any DTCs, test the system for normal operation. G552286t25 : CHECK THE DPF TEMPERATURE SENSOR GROUND CIRCUIT 1. Measure the resistance between: GB10, harness side C101, harness side Pin 02
F3
Is the resistance 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): - DPF temperature sensor connector. - DPF temperature sensor. - ECM connector. - |
