Diagnostic Aids





Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction.
The following are possible causes of the malfunction:
^ A powertrain control system malfunction
^ An internal PCM malfunction
If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections. Component Tests and General Diagnostics
