Intermittent Codes
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
An intermittent code is a DTC occurring intermittently and is most likely caused by defective wiring, connections or hydraulic leakage. Intermittent code indicates a failure does not exist every time PCM checks the system. Intermittent codes must be checked under conditions in which they would be set.
NOTE:
A reset counter located on Chrysler's Diagnostic Readout Box (DRB-III) scan tool, indicates number of engine starts since DTC was set. This aids in determining if DTC is hard or intermittent. If reset counter shows less than 3 engine starts, it indicates a hard code. If reset counter shows 3 or more engine starts, an intermittent code exists.
