CEL Code 1381 - Ford Forums

bilyo · 09-21-2007, 19:28

I did a seach of all of this forums posts and found a few with the same or similar problem, but didn't find any answers. Please allow me to post it again. maybe some of you have since found the answer.
I have a 1998 Contour w/4 cyl Ztec and auto trans. Just under 60k miles. It starts and runs good. No noticable symptoms, but check engine light has been on for a long time. Computer readout says P1381, Variable cam timing overadvanced (bank #1). I'm told that either the cam position sensor or the cam solinoid is bad and a quote to fix it makes you reach for the oxygen. Can you stear me to some clear concise instructions for finding/checking/fixing these components. Is any special equipment required other that a VOM?
Thanks,
Bill

Here is a site to check that helps explain what could be causung the problems and how to check. Also some people that have had this problem said that their cars are also bucking while driving. If yours car isn't doing this maybe try to get the code erased from the car and see if it comes back.

Other forums that I have checked thou say to change the oil in the car first due to it might be contaminated.

Hope this helps.

As I understand it, the P1381 code indicates that the valve timing is too far advanced when the ecm is calling for it to be retarded. Usually, because this is the default position, it does not cause any running problems. At least that's what I'm experiencing. I don't think it is an oil problem. The CEL has been on through many oil/filter changes (synthetic every 3-4000 miles). I've removed the code many times and it always comes back.

Thanks for the link. One paragraph explains how to check the vct solenoid while the engine is running. One step is to "back probe" the ground side of the solenoid and then ground it briefly. Does anyone know what it means to "back probe"?

Thanks,
Bill
