NOTE:
For identification of ECM/PCM harness connectors and wire terminals, see PIN VOLTAGE/CIRCUIT RESISTANCE CHARTS article.
Sensor operating range information can help determine if a sensor is out of calibration. An out-of-calibration sensor may not set a trouble code, but it may cause driveability problems.
For individual component and system diagnostic test procedures, see SYSTEM & COMPONENT TESTING article.
