To all, this weekend I changed the timing gears and chain, water pump, radiator, reservoir, coolant, and hoses on my 2001 TJ with the 4.0.
Everything went really smooth and got it back together no problems, and it runs absolutely wonderful when I drove it today (I let it set for a few days so the RTV and everything would set up correctly). BUT, I got a check engine light and the code is 1391, camshaft positioning sensor. I know for sure I had the timing marks lined up perfectly before removing the old chain and gears and putting the new ones one. I have not ever had that code before, only after changing the timing gears and chain. I did set the alternator and bracket against it when I removed them to get to the timing chain cover, but that should not have moved it or anything.
I am prepared to get a new sensor, but thought I would ask for some input from the board before doing so. Again, I am certain I put the new gears and chain on correctly and the timing marks lined up perfectly. The old chain was so loose it could almost come off without removing the gears, and the new one was extremely tight going on.
So, any thought before I put a new sensor on? Thank you for any input, it is appreciated.
