Pleas confirm - you are saying that your jeep is showing this entire list as faults?

Vladimer

That is correct.

The Jeep seems to still drive as it did prior. I was slowing down to a red light, ding, CEL goes off. Checked it and got 7 codes initially. They were cleared with the flashpaq and once driving they came right back. I am hoping it is a grounding issue somewhere which cold still be a pain to find.

First time it popped up I got these codes.

P0010 - "A" Camshaft Position Actuator Circuit (Bank 1)
P258B - Vacuum Pump Control Range/Performance
P2503 - Charging System Output Low
B1638 - Right High Beam Control Circuit High
B1634 - Left Hi Beam Control Circuit High
B1630 - Right Low Beam Control Circuit High
B162C - Left Low Beam control Circuit High


Replaced the serp belt and cleared the codes and now getting these ones.

P0010 - "A" Camshaft Position Actuator Circuit (Bank 1)
B1638 - Right High Beam Control Circuit High
B1634 - Left Hi Beam Control Circuit High
B1630 - Right Low Beam Control Circuit High
B162C - Left Low Beam control Circuit High

My low beam and high beams work and it runs fine as well.

Not sure where the cam shaft sensor is on the 3.6 but since we have VVT the timing would be changing on the fly anyways, no?

There was a TSB for a PCM update in 2012's due to some random codes. Not sure if they are for any of the codes you are seeing.

Vladimer

I'll check it out and see if mine was ever updated.

Anyone know if the only grounds that the TIPM uses is those little bolts along the fender wall?

Vladimer

No luck. Looks like the TSB is for the below and doesn't match what I am getting

TSB 18-054-11 released 12/15 for a pcm update.

Replaced the cam shaft position sensor and after a 500km round trip yesterday, NO CEL yet!

The indash fuel calc also went down from 19.5L/100km to 12.7L/100km which seems rather excessive as it is usually 14-16L/100km if I drive nice on the mileage tune.

Great news... hope that solves it. keep us informed.

Vladimer

It was promising, but no luck

~600km later, exactly same problem as before.

Next to no power in 6th gear, 5th runs fine..ish. When going over overpasses I need to have the pedal to the floor to keep it at speed.

Same codes as before

Vladimer

Seems the headlight codes are common with guys having truck lites/hids/speakers/etc... its a note kind of CEL and doesn't flag on its own, only displays when another DTC pops up.

That goes back to the cam position sensor that was just replaced
