Check Engine-Multi Sensor Incomplete-Computer?
I recently had a check engine light on my 04 grand cherokee 4.0L 6Cyl. After fixing an evap line break check engine went off until 15 miles later I got another check engine light on. Using advance auto parts diag. tool I got the following
P0117: Coolant Mon. Sensor 1 Low input voltage.
and the following
Evap Mon Sensor - Inc (incomplete)
O2 Mon Sensor - Inc
Catalytic Mon Sesnor - Inc.
Seems odd that I would go from a no check engine to multiple sensors incomplete with the coolant showing low voltage. Is there a way to check if the coolant sensor really is the problem or is the PCM or jeep computer having issues? If it is the PCM/TCM or whatever is the carcomputerexhange.com a reliable source to save money?
