P1280 ICP Sensor Circuit Low

Truck seems to idling a little rough but not bad. But it is throwing several codes but the 1280 is the one that I am guess is causing the engine light to come on.
The pigtail seems to be fine but the wire does look like it is getting pulled down slightly. Can I cause some damage if I drive it?
Attached a few files....

I can pull the codes from the truck but I am sure I am not using the AE to the full advantage. By the way if anyone really knows how to use an AE let me know and you can give me a lesson, and use it all you want on your rig. I am on cougar mt in Renton.

Thanks,

Kyle

I believe that is your oil pressure sending unit in that picture. I don't think it looks bad but someone else might see something I don't. Here's an instructional thread with gobs of information.

My bad you are right that is my oil pressure unit. My ICP wiring looks much better though. Is this a code saying that I need a new ICP or wiring or both?

Have you unplugged the ICP and checked the plug for oil?

I did unplug the wire part and it looked good. Should I unscrew the part and take a look too?

Oil in the plug of the ICP sensor is an indication of failure. If there is no oil there I'd hold off on that. Did you clear the codes when you hooked up your AE? Old codes remain until cleared. You can disconnect the ICP sensor and run it, the PCM will issue a default number and it will run. If you disconnect it and your problem goes away then you know what sensor is bad.

I unplugged the wiring and the plug looks nice and clean. Should I unscrew the actual ICP and look for oil in there?

AE Tests:
I cleared all the codes and then ran the AE again. I got the same error p1280 error along with p0472. Then I cleared the codes and unplugged the ICP started and then ran the AE and still got the same error.

Thoughts???? thanks

You dont need to look at the other side. The other side will have oil as it is exposed to the oil rail inside the head.

When you disconnect the ICP sensor does the truck seem to run better? You will get that code with the ICP unplugged. What were checking for is a ICP sensor thats not reading correctly. If you unplug the ICP sensor and the rough idle goes away, your ICP sensor is likely reporting false readings to the PCM.

So the idle was just a little rough at sporadic times, not consistently. I unplugged it and did not notice a difference. But with the current sporadic rate not sure how I would tell. Any ideas????????????Thx

Wait until it is idling rough and unplug the ICP to see if the idle smooths out.

So I can unplug my ICP and it starts just fine. I ran the truck today to the store and back with it plugged in and truck showed no symptoms. Should I just replace the ICP? Is there a way to test the sensor?

From your signature:
DP Tuner (45mph valet, Drive Thru, 40 tow, 60 tow, 80 tow, 60 Econo, 80 Econo, 100 perf, 120 race, 140 Extreme, 140 Aggressive)
I'm surprised that others haven't already caught on to that and commented; especially Tugly

If you have stock split shot injectors, anything over 80hp is wishful thinking. The injectors don't have enough reserve capacity in them to make more power.

Regardless of injector size, "hot" tunes; especially from certain tuners, are known to make it LOOK like you have a bad HPOP, by running excessive FIPW, and bleeding off ICP.
