Set Condition

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The Powertrain Control Module (PCM) detects that the sensor does not output a voltage greater than a calibrated high voltage value and less than a calibrated low voltage value within a specific time period. If the voltage pass values are not achieved after the total accumulated test time, a pending fault will be set. An active fault is matured on a second trip failure. Three good trips will turn off the MIL.
