code/sensor questions

[eric99f250]

i just pulled some codes from my truck this afternoon i got

p1280 icp circuit out of rangle,low

p0472 exhaust pressure sensor low

p1690 wategate solenoid control circuit

p0236 turbocharger boost sensor A

p1211 icp pressure above/below desired

p0476 exhaust pressure control valve performance


my gf's dad said i should start by changing the exhaust pressure sensor then the wastegate where is the tubo boost sensor? and should i change the icp too?

Is there anything wrong? Looks to me like a harness got unplugges somewhere or something for all of those problems at once. The icp sensor code can sometimes just be caused by a chip and im guesing some of those other ones could too? Heres a bump for u anyway.

well kind of its been running kind of sluggish lately i just changed the driver side valve cover gasket could only do one...started raining the harnesses all looked good no cracks im gonna get a new wategate and see if the solenoid is good yet idk its been driving me nuts lol

To many codes, they could be months old or older. Clear all of them and see what returns. The EBS code is probably due to carbon build up on the base of the sensor and in the tube, clean it with brake cleaner and you may be okay. I was able to clean mine twice before I needed a new sensor.

Im with Kevin here. Clean the Exhaust backpressure sensor.

The rest of the codes are because of your chip commanding more ICP and the truck making more boost than ford spec.

The link above tells you how to do it

Check the dealer or an IH big truck dealer. IH will probably be the cheapest

i was gonna try the dealer but if i can get them cheaper elsewhere ill do it
