Diagnosis With Pin Voltage Tables


Once an actual PCM pin voltage reading is recorded, it can be compared to an example from a vehicle with "known good" values. In the example below (from a 1990 Crown Victoria 5.0L V8), the Value at Hot Idle for the EVP sensor signal (0.4v) is the "known good" value.
