99 jeep xj 205000
I was just driving yesterday and now I have a p1391 code that has the CEL on AGAIN. AZ printout shows this code to be CPS or CKP.
very recently I had CEL with a p0340 code and I just replaced the Cam position sensor, the CEL then disappeared.
Before that Ive had a battery temp sensor light that brought the CEL up off and on over the past few months. I havent replaced this one, but I did pull it and tape/solder some exposed wire and added some dielectric grease to the plug which seems to have worked, but I still plan on replacing this sensor anyway.
both cam/crank sensors are Mopar, the cam about a week old and crank sensor about a year old.
This is very odd that I keep getting these codes with a CEL light as of recently. The only thing I can figure as a common trait between the battery temp sensor and the new CEL is it had rained out. The jeep seems to be driving just fine, Im curious if the CEL will shut off on its own...
last time before replacing the CSPS I let the jeep run and carefully wiggled many wires/plugs around to see if I could get any odd responses, but nothing was noticed.
I plan to visually inspect the undercarriage tomorrow
is there anything in particular that will start spawning CEL this often?
im not quite sure where Ide start to check this because it seems too soon to have an issue with either of these sensors right?
