2002 2.7 Fixed: 0068 & 0108 codes - MAP Sensor
Great forum and members here. Just wanted to add a quick experience I had this past weekend with my 2002 2.7 SE. Driving home the other night she started sputtering while accelerating. CEL came on and I read the codes (2) as soon as I got home:
P0068 - Manifold Pressure/Throttle Position Correlation - MAP sensor signal does not correlate to throttle position sensor signal. Possible vacuum leak.
P0108 (M) - Map Sensor Voltage Too High - MAP sensor input above maximum acceptable voltage.
After checking the forums here I figured I'd replace the MAP Sensor ($120). Probably one of the easiest if not THE easiest part to get to on an 02 2.7. Plan on it taking you longer to go to the parts store and come back than it takes to change it. Even if you live next door to the parts store. Speaking of stores, here in SE VA, Advance couldn't order it, PB couldn't find it, Napa is closed on Sundays and an Autozone had it in stock (not closest Autozone of course but in the general area.)
Problem solved instantly (actually after I left the NEG cable off for 15 min. to make sure codes cleared.) Drove it last night & to/from work today and she's happy as ever.
