This is making me crazy. I have been getting P0341-2 for 2 months now on the '95 SE. "Ignition problem" and "intermittent cam position sensor signal".
Checked for, and cleaned the little cylinder magnet interrupter on the cam.
Replaced the cam position sensor. (new, just in case)
Replaced crankshaft position sensor (new)
Replaced the wire harness that goes from the two sensors to the Ignition control module.
Replaced with a used, but definitely working ICM, cleaned it and all of the areas involved.
Replaced with a used, but excellent reading set of coils.
Checked and cleaned and reconnected the battery cables so many times, I dream about them at night.
The scantool tells me the battery is running between 13.9-14.1 volts.
Just looking at my notes..
When the CE light comes on, I can clear it by turning off the car and restarting. P0342, which is the fatal error, clears. Leaving P0341. Sometimes, I'll drive 15 minutes and the CE comes back. Sometimes I'll drive for a few hours before it comes backs. My scantool doesn't give me a freeze frame on OBD1, so I can't figure it out from there.
This just smacks of being something electrical, just a quick short. It happens so fast. If i clear the codes with the scantool and drive around reading the codes every few minutes, there is nothing, then the two codes appear at once.
It started to happen a couple weeks after I replaced the water pump. There was antifreeze involved. So one direction I can go is the belt (which is a gator but could have gone soft), alternator, and battery. The other direction is the harness that heads towards the PCM and wherever else (and that looks like a pain to find and follow them). From searches, usually if the PCM is whacky, it throws more codes than just those 2. Only these two have been involved. I would just deal with it, but when the P0341 comes on, the PCM has the injectors doing some averaging thing and the car isn't as smooth or quick.
Will Rice Central be able to pick up something in a quick test of the battery and alternator, when the problem only happens occasionally?
I need some direction. I've had 2 independent wrenchers check it out, and they didn't have any good ideas. the only other help left would be to have it checked by a dealer. I just hate to turn it over to the enemy after fixing everything for the past few years with help/advice from everyone here. It'* great car mechanically, i hate to lose her over something like this.
Any thoughts would be appreciated. thanks.
