Secondary Ignition Circuit

WARNING: This page is about a different car, the 2006 Dodge Grand Caravan, 2006 Dodge Caravan, and 2006 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

The PCM cannot detect an inoperative ignition coil, fouled or worn spark plugs, ignition cross firing, or open spark plug cables. The misfire will however, increase the oxygen content in the exhaust, deceiving the PCM in to thinking the fuel system is too lean. Also see misfire detection. There are DTC's that can detect misfire and Ionization shorts in the secondary ignition circuit, refer to POWERTRAIN DIAGNOSTIC PROCEDURES article for more information
