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.

Leak Detection Pump (LDP) switch operation is monitored immediately after a cold start with battery/ambient temperature 40-90°F (4.4-32.0°C) and engine coolant temperature within 10°F (-12.2°C) of battery/ambient temperature. DTC will set when state of LDP switch does not change when solenoid is energized.
