confused P0304 Camshaft Position Sensor

P0304 Camshaft Position Sensor A Circuit Bank 1 or Single Sensor
Thats what on my scan tool?

Ford E150 4.2L V6 With 126000mils.the code keeps coming up almost every day.

Replace it the coil OEM & The camshaft position sensor OEM, The wires & the spark plugs have 15000 miles on them.

Symptoms can include:
  • Hard starting
  • Rough running
  • Loss of engine power

ONLY When i take off( stop & Go) it loses power, is like wants to shut off ,(some time it will pop in the air box) (THE code will came up), after that is fine. Going in the highway 60-80mph is fine no problems, it is mostly on city driving.


Any one head this problem please help?

It sounds like your timing slipped.

Has there been any work on the cam shaft that required the chain to be removed? You didn't mention the year, but if you have a distributor rather than coil packs, that is something to look at. It could be an issue with the sending device on the cam shaft. Dealt with one on a Mitsubishi where the sending device was in side the pulley for the timing belt. For some reason, it had separated just a hair but was reaping all kinds of havoc even though it was still attached. What year is the van, we might be able to narrow down the possibilities.

Re: P0304 Camshaft Position Sensor

That code you posted is for a misfire. Why do you think there's a camshaft problem? They can have cam positioner problems but not setting that code.

Re: P0304 Camshaft Position Sensor

I'd take it to Autozone or Advanced auto parts to see what codes they pull. They don't charge for that.
