Hopefully this story helps someone else. I started having some electrical problems with my 2005 Sport with a 6 speed. I started getting an intermittent no crank situation. Jumping the starter would crank it, but no spark. I also noticed that my OPDA was a little loose, and it caused a crank/cam disagree code. I tightened that. No more codes that way. I still had occasional no crank/no start problems with no codes. I went the cheapest route I could think of. I replaced the cheapie crank position sensor that I put in last year when I replaced a disintegrated throw out bearing. I did the clutch at the same time, of course. I broke the crank sensor putting the transmission back up into place. Remove that like the instructions say. Oops.
Anyway, after replacing that sensor, everything was fine for about a week, then this:
P0032 heater control circuit both banks and circuits.
P0031
P0038
P0037
P0051
P0052
P0057
P0058
All of those came on at the same time and the Jeep died. I cleared the codes, and drove another 1/4 mile and it happened again. Haven’t seen those codes since.
Since then, I have been frequently losing all my gauges, gas light on, MIL on, and code U0155. Sometimes it is self healing and the MIL even goes out. It usually shuts down a little while later. It usually restarts. If not, disconnecting the battery terminal and reconnecting will allow it to start. Last time I did this, (almost all of this was on a camping overnight with my daughter) I left the battery disconnected for about five minutes while I helped my daughter with something else. 42 minutes of good living, according to the clock on the radio.
The one other anomalous code that I got was P0508, Idle air control system circuit low.
I have also gotten an occasional P0300 Random/multiple cylinder misfire
Coincidentally, these would most often occur going downhill at idle/engine braking.
Yesterday I put my new PCM in from Wranglerfix. 5 minute procedure. Fired up and has been working fine for two days now. I ordered that PCM on Tuesday, late afternoon. It arrived on Thursday. I was out of town, so I didn’t get it in til yesterday. I have a few hours of driving on it, and it is a different experience now.
I am fairly confident that was the answer.
I bought this Jeep a year ago. I should have the rest of the “isms” worked out of it soon.
