I've got a van that will not stay running while going down the road (shuts off after a few miles, wait 15 minutes or so, it'll crank and then shut off again down the road), but it will not die while idling.

It's been looked at and things have been done (CPS, fuel screens, etc, the usual).

We checked the ICP sensor and there is oil in the connector. Could this be the cause of the symptom above?

We've got other trucks we could swap the sensors to check, but the van apparently is a PITA to get the ICP sensor out.

Thanks!

 

Yes, sounds like the ICP is bad, there should be no oil. You can test it by unplugging it and running it, if the problem goes away with it unplugged it's definately the ICP.
