Question about 2002 Jeep Grand Cherokee
Just one word.
ok all pretend a question
what is that, its a DTC.
what does it mean, it means the EVAP vents are failing. or the gas cap is loose.
put the cap on tight, and reset the codes, with any scan tool
then drive see if it comes back.
if yes, a new cap
if still bad, the FSM has the lost weekend of test to find it.
its NON trival if you dont have shop air , and or shop vacuum tests tools. the tank vent system is breached, why ,is obvious.
crackes. in hoses etc.
or the PCM evap testing parts are bad, all this and every single
test is fully covered in any cars FSM, not just jeeps.
get the FSM, and read it.
or login to alldata.com and read the EVAP chapter.
