Diagnostic Aids

Check for any of the following conditions:

• Check for a faulty electrical connection to the ECM.

An intermittent malfunction may be caused by a fault in the ECT sensor electrical circuit. Inspect the wiring harness and components for an intermittent condition. Repair any electrical circuit faults that were found. If a DTC P0119 cannot be duplicated, the information included in the Freeze Frame data can be useful in determining the vehicle operating conditions when the DTC was first set.
