Check engine light

I installed a 2" spacer lift a while back and about a week after, I have had problems with the check engine light staying on (code P0016). When I am getting on the interstate, the engine struggles and I have to back down on the throttle a bit and slowly get up to speed. Could this be a result of the lift without a t-case drop? I have not had any trouble with vibrations or anything since I installed it. Any info would be greatly appreciated. Btw it is an '05 sport 4.0L with 31's and I am new to WF so bear with me until I get the hang of it.

That code must be something specific to later TJs. I looked through my service manual and couldn't find a P0016 code. Hopefully someone with a later model TJ will chime in with an answer.

Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A) Read more at: http://www.obd-codes.com/p0016 Copyright © OBD-Codes.com

This is the description for the code. It has a list of several possible causes. It may just be a bad crank/cam position sensor but I just wanted to see if it may be because of the driveline angles. I would rather spend about 50 bucks to get a t-case drop (if that is the problem) than over 400 for that sensor replacement that I was quoted parts and labor.

A 2" spacer lift would not cause drive line issues like that. Maybe minor vibes but not engine issues. It is possible you had the same thing I had. I replaced my track bar and about 30 miles after my O2 sensor crapped out throwing up a code. Just dumb luck that a sensor takes a dump on you after you do an unrelated mod. Hope this helps

Was thinking the same thing, very unlikely that the spacer lift install has anything to do with you crank sensor going bad. Just finished installing my lift kit Friday, that night my alternator crapped out

That's kind of what I figured. Thanks for the help guys. Hopefully I can get it resolved pretty soon and I'll post what I do to fix it.

Update: tried a new cam sensor today and it did not fix the problem. That leaves the crank sensor. Tried the cam sensor a) because it was only $40 and b) because I heard that usually when the crank sensor messes up, the vehicle will not even run. Hopefully I can get this done pretty soon so if anyone else has this trouble they will know what to expect.

Problem solved. Ended up being the oil pump drive assembly. Got worn down pretty good.

I have the same code right now. How did you figure out it was the oil pump drive assembly from that code? Thanks

I did a little searching online and many of the things I found on it said it could be the crank sensor or the cam sensor. I tried the cam sensor first because it was the cheapest and easiest to do. Didn't work so I tried a crank sensor. Finally, I just got tired of messing with it and took it to my local mechanic and they pulled the opda and saw that it was worn out. You can tell from the pictures that it was pretty bad. I left the cam and crank sensors on so I shouldn't have to replace them for a while. Let me know if you have any questions and I will be happy to help you out. As of right now, it's running great and haven't had a bit of trouble.
