Monitored & Set Conditions

WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

With the engine running at idle, MAF less than 250 mg/tdc, air temp between 0-19.4°F, enable after coolant temp greater than 158°F or air temp greater than 19.4°F, coolant temp between 19.4-266°F, canister purge less than 100 percent duty cycle, and no VSS, MAF/MAP, ECT, TPS, ETC, CKP sensor DTCs or any fuel system or injector DTCs. DTC will set if engine speed is 100 RPM or more below idle speed for 7 seconds. This is a two trip fault. Three good trips to turn off the MIL.
