ICP Question
So I have these ICP codes, p1210, p1211, p1280, p1282. Looked up definitions, "ICP expected level", don't know what that means. "ICP not controllable, pressure above/desired", don't know what that means. "ICP circuit out of range", don't know what that means. "Excessive ICP", don't know what that means.
Also, p1209. "Injection Control System Pressure Peak", don't know what that means either. My truck is running good, but it is still loud as heck. Until I come to a stop sign or light, my idle go's down and seems like it's going to die. But it never does.

If you can, clear the codes and then see which ones return. 2nd - disconnect the ICP sensor and check to see if there is oil on top of the sensor - then try to start it with the sensor disconnected and see if it idles or runs better.
If it does run & idle better then replace the sensor.
With The ICP sensor disconnected the PCM (computer) goes off of a data table since it can not get e reading from the sensor. So if it runs better with it disconnected it usually means the sensor went bad.

Tried disconnecting sensor awhile back ago, ran like ****.

Is your truck tuned in any way? Do you have modifications? Were you just scanning, or are you troubleshooting?
Those codes may have occurred some time ago, but if they pop back up - you'll need to do data logging to find out what's happening.

P1280 is Circuit out of range. Meaning the sensor is bad. It could also mean the truck was on when the sensor was unplugged. Watch this video about P1280. When youre done, unplug the ICP sensor and see how your truck runs.
