P2285 Injector Control Pressure Sensor Circuit Low - Diesel Forum

isofuncurves · 08-11-2007, 11:32 PM

Hi all. I recently took my newly acquired 03' 6.0L PSD on a trip from San Diego to Zion, Utah hauling a 7,500lb trailer. When pulling up hills I noticed a "Chaaah......Chaaah.....Chaaah...." sound. The engine seemed to dip about 50 rpm on each "Chaaah". Speed was typically 55-65 mph but I wasn't on the throttle hard.

Before I left I notice that the CEL light was on. I took it in to change Tranny and Diff fluid; the shop said that everything looked great. They also told me that the DTC code was P2285 - Injector Control Pressure Sensor Circuit Low. I got a reader and checked it myself. The code is still the same and only code. Freeze Frame data was Air Flow Rate from Mass Air Flow Sensor: 0.00 lb/min, Coolant Temp 172F, Intake Air Temp 151, Calc Load 0%, Engine RPM 0rpm, Intake Manifold Abs. Pressure 29.8 in Hg. So nothing there looks strange except for Air Flow, Load, and RPM unless code is thrown before engine start?

Seems like it could be related. What should I be looking at?

Thanks for any help.

Same thing on my Excursion a few weeks back, take it to a dealer for powertrain warranty replacement of the sensor and be sure they change the wiring harness as well, fuel could be leaking and weaken the wire insulation.

Since doing mine no more problems.

Good luck!

New Symptom today!! The patient died.

This morning the X starts, runs for 10-30 seconds and quits. It idles smoothly and then stops. It doesn't sputter and choke it just stops clean. The P2285 is still the only code.

I'm wondering if I should change the fuel filters even though they were just changed 7,000 miles ago. Anybody have any suggestions? If I can't figure it out tonight...it's getting towed to the shop.

Thanks,
Carl

PS: Grampy, you have a PM.

Today it is running well enough to get it to the shop. I wish I could say it was something I did but can't. Taking it in for service in the AM.

Is there any oil coming down the back of your motor, by any chance? Possibly a biased/leaking sensor... a couple of simple tests/checks can rule this out...

The dealer has the vehicle now. I did notice some oil on the rear of the engine when I changed the fuel filters (and looked around). The dealer is going to tear down the turbo and possibly replace it. They didn't mention the ICP sensor which surprised me but, we will see. I should be getting the vehicle back on Tuesday. I'll post results then.

Umm, not to make you worry, but why would they tear down the turbo to repair a stalling problem? Thats like changine the batterys because a headlight doesnt work. Same logic anyways.

Picked up the X today. Dealer replaced the ICP sensor and pigtail for the P2285 code. Sensor tested bad and had oil leaking. They also cleaned the turbo. Work was completed under warranty with $100 deductable. The X is running great. While it was in I had them replace the rear hatch locking mechanism. At nearly $400...maybe I should have done that myself. My truck is running great and that is all that really matters.
