Not sure if I should post this thread in the engine/ drivetrain forum or electrical. 1999 F250 Super Duty with Triton V10. Fuse #3 in the cab which is for the cigarette lighter and OBDII blows the fuse as soon as it is inserted . I think a sensor has a short causing this, anyone have any ideas on how to find the cause?:confused: Truck hit a deer about two months ago and has some front end damage, but airbags did not deploy. Two sensors I have noticed damage: 1> Passenger Side behind front fender and headlight (Air Bag Sensor?) which is where the body damage occured, and 2> on the front of the valve cover on drivers side (both wires broken off).

If an airbag sensor was shorted you would have a warning light on the dash lit.
Remove the wire form the cigar lighter and see if the fuse stays OK.
Can you get a picture of the valve cover wires?

I'd also bet that the most likely culprit is the socket to the cigar lighter.

Cigar Lighter was the culprit causing the fuse to blow. Now with the OBDII operational I pulled the following codes
P0390: Camshaft Position Sensor 'B' Circuit
P1390: Undocumented. Mentioned in a TSB for one of several codes for hard starting/ rough running.

Now I am having problems taking the connector loose on the sensor mentioned above with the broken wires. I thought it was the Camshaft Position Sensor, but what info I have found on the internet has it located in a different place.

Will be buying a Hanes Manual today if the parts store has one on the shelf.

See if this helps you to locate it.

Yep

That is the sensor in question. I finally got the connector off, but now I am having a hard time locating a new connector to replace it. Putting a salvage yard off until the last resort, because the only decent one we have around here usually comes with a two hour wait because they stay so busy. The 'sensor' behind the passenger side front fender turns out to be the horn. Any ideas on where to locate a connector for the CPS?
