Question about 2002 Jeep Grand Cherokee
Cleared once, replaced gas cap. Egine light came back on with the same code.
This code is caused by the leak detection pump for the evaporative emissions control system, this is a common fault in your year and model, there are factory bullentins about the code, to replace the pump do the following. As noted in the procedure pay close attention to the condition of the vacuum lines to the pump.
The LDP, (leak detection pump) is located in the left/front corner of engine compartment below the air cleaner housing. It is mounted to left/front inner fender sheet metal. The LDP and LDP filter are replaced (serviced) as one unit.
