Look for traces that a small critter might be nesting in the van somewhere. In recent years automakers have switched to a wire with soy based insulation because it's less expensive. The downside to this is the insulation is now more appealing to rodents to chew. Our vans seem to pre-date this problem, but it's still a problem especially as the cooler weather approaches.

I'll do that. I did find some rat poop in the engine compartment once, but that was two or three years ago. Might have left a farewell message to pay me back for poisoning him. Thanks for the idea.

 

Was this fixed? Was it the harness? I had a bad pcm which kept throwing bad iadle air controller codes. Replaced the iac twice, but resolved the problem when I replaced the pcm. Just FYI.

 

After having collected all these opinions and advice, I tried yesterday to put them into action. I discovered that I am much too arrogant for my own good! I can't even locate the sensor let alone the wiring. And if the PCM is what I think it is, it is bolted to the firewall behind heavily wrapped wire bundles and the odd pipe/hose. So I am going to rely on the OBD2 reader and software I bought to tell me if the fault code changes or some additional code shows up. If it does, I will let a mechanic do the job. In the meantime, the van runs fine and I am going to leave it alone.

Thanks to all who tried to help. Little did they know the level of incompetence they were dealing with.

 

On your model the cam sensor is the pickup coil inside the distributor, and you have to remove the doghouse to get to the crank sensor.

 

Thanks, Alloro, for not giving up. I'll have a look.

 

Just wondering if this issue was ever solved.

 

Yep...also if the CPS was bad, more than likely the van wouldn't run...

The code also states the sensor coil in the distributor could be faulty too...Or the distributor could have a cracked cap. rotor or junk inside it...

 

I can imagine he fixed it or drove it off a bridge in disgust by now... it's been a year since he posted ;-)

 

It's been so long since I last looked at tbis thread that I've forgotten how to post a reply. The situation has not changed in that the check engine light stays on and the code stays the same. The car seems to run ok, although I may be losing some economy/mileage.
