Pin Voltage Charts

NOTE: This article is generic in nature and all information does not apply to all vehicles. For vehicle specific information, see the appropriate articles in the ENGINE PERFORMANCE category.

These are supplied (when available from manufacturer) to quicken the diagnostic process. By checking pin voltages at the Powertrain Control Module (PCM), you can determine if the PCM is receiving and/or transmitting proper voltage signals. Pin charts may also be referred to as PID charts by some manufacturers.
