Ok had my buddy run the comp. again on it it says " Injector control signal circuit out of range low" then running the numbers its shows ICP 0.00 then it jumops to 0.01 then back to zero The injector control pressure is 725 and Inj pressure 14 Pcode 1280 where can I find the Injector control module? and would loose wires under the valve covers caused this before I remove them and check it

DC2 DIAGNOSTIC TROUBLE CODE (DTC) P1280
DTC P1280 indicates injector control signal circuit out of range low was detected during KOEO Self Test or during continuous diagnostic monitoring.
Possible causes:
biased ICP sensor/PCM
open ICP sensor circuit
short to SIG RTN or PWR GND on ICP sensor circuit
open in VREF circuit

Make sure the wires on the large square connector on the left valve cover aren't chaffing on the valve cover
Key on engine off ICP voltage should be around .3 Volts and pressure should read Zero Psi..

I did check the wires on the left side the valve cover they were rubbing but when i removed them and turned them upside down to see underneath they looked fine i taped them up any way , could it be the ICP sensor? I know to unplug when its running rough to see if that changes the engine but its intermiitant and runs rough usally at a light this just started happening yesterday. are the reading i have wrong?

Mine did the same thing, turned out to be a oxidized pin on the ICM located up inside the drivers fender, had to remove the inner fender well to get to it, removed the connector, cleaned it up, and put it back together, been working for 7 months now.

update... after reading all day I checked a bunch of things behind the HPOP the IPR valve has a wire connector where the two wires go into the plug they were worn, exposed and touching each other copper to copper I temp fixed for now by sliding a bigger wire sheathing over them until i can buy new connector harness and i also checked the ICP sensor cleaned all the oil inside the connector itself after i started and checked the icp again it still had oil inside the three little prongs so im assuming bad icp,,,, also seems to idle alot better now im assuming b/c the IPR valve is operating properly

ya if the icp has oil in it, its safe to assume replacement is a good thing.
