'00 Code Help
My Excursion has been running poorly upon start-up. I had a similar problem once before, a new fuel filter fixed it. This time, that did not help. I just read the codes and got the following:
P1211 - ICP Not Controllable - Pres Above/Desired
P1212 - ICP Voltage not at expected levels
P0470 - Exhaust Back Pres Sensor Circuit Error
P0340 - Camshaft Pos Sensor Circuit Error (bank1/1 Sensor)
Are these all related? What is the recomended fix? What is the ICP and how do you replace it?
I replaced the CPS a year or so ago, but it could be going out again, although it behaved differently back them (the classic dieing).
Thanks

Sounds like the ICP sensor has headed south - Driver side front top of engine next to HPOP reservoir 2 wire sensor harness
Clean the EBP sensor and tube
Clear the codes and if 340 comes back then replace it once you are sure it is not a wiring issue. There is a spot above the CPS where the harness attaches to the front of the engine that can chafe if it comes loose
