Hi - I have a 1997 Ford F-350 diesel Crew Cab 220,000 miles. I use this as my work vehicle and go throughout the Midwest with it.

This past week, I was in Indiana and had some trouble. It happened 3 or 4 times, and each time within 1 minute of startup. Suddenly the idle would change noticeably (sounded like it was missing) and the check engine light would come on. When this happened, I would pull into a parking lot, rev it a little, and then turn the key off. I would then re-start it, she would run well, and the check engine light would not come back on. Each time the problem happened, it would be the first start of the morning. I drove back 500 miles to Wisconsin without a problem.

I took my truck down today and got the codes read -two codes came up and here is what the mechanic wrote down: P0344 Camshaft post. Circuit and P1211 Injector Control Pressure High/Low. He thought I might have an issue with my CPS and that this might be triggering the Injector code - does this seem reasonable to you all and sound consistent with my issue? He kept his code reader hooked up and started the truck and reported oil pressure of 580 psi - he said anything over 500 was good. He suggested I get the CPS replaced and said my problems should be fixed.

I try to keep this truck working well because a breakdown far from home can be very expensive for me. Should I just replace the CPS and hope for the best or does anyone out there have a different idea of what the problem could be?

Thanks for the help - great site!

 

Look at the ICP sensor , it may have oil seeping from it ...

 

when you crank the truck over does it register rpm on the tach before it starts. if no you have your answer. since you got the cps code i would change the cps anyways and if it don't fix the problem then you have a spare in the glovebox for when yours does go out. the CPS costs about $25 at ford. the p1211 is a common code for these trucks. if your truck is stock then i don't know why you would set it. do you have any mods done to this truck at all?

 

Thanks for the feedback.

I am not sure what the ICP sensor is...what is it and where can I find it to check the oil situation?

This truck does have some mods - 4" exhaust back from turbo and a Banks chip.

The truck ran weird exactly when the Check Engine light came on....would both of these codes get the Check Engine Light to come on?

Thanks,
Jason

 

When starting, it does register around 300RPMs before it starts...

 

1211 will set a CEL , CPS is soft ...

unplug the wiring connector , if it is leaking , it will be under the connector ..

 

That is good to know... the mechanic who took the codes off the truck seemed to think if the CPS was not working right it could cause the P1211. Do you guys think that is possible?

 

Thanks for the picture - there is no oil at the ICP - everything looked very clean when I took off the connector....
