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): - Open circuit in sensor power line - CMP connector - CMP sensor - Camshaft sensor
target wheel - ECM connector - ECM
-> No
REPAIR the out of limits resistance in the CMP harness or component. This may be due to a short or
open circuit, depending on the result of the last measurement. For additional information, refer to
the wiring diagrams. Clear any DTCs, test the system for normal operation.
