First issue: My oil leak that only happens in the winter months is back. This leak is substantial compared to the small drops here and there in the spring and summer months. Size is approximately 6-7 inch diameter. The amount of oil is always the same after driving for awhile and then while sitting it drips from the little knotch on the housing.



second issue: My check engine light came on a few days ago. As I was leaving work the other day I exited the lot and gave some gas (not flooring) it seemed to be ok for a second and then I let up and lost all rpm's. no boost and it just fluttered out until it stalled. The only thing I have done is put some anti gel stuff in the tank 1 1/2 fill ups ago. I was able to started the truck again after 3 cranks. I took it to autozone and they tried to read it and came with a code of P1211. After checking here it says its the ICP. I had replaced that last winter. Could that be broke again? or is there more to the 91211 code that that?

Thanks

 

Cold weather only leaks tend to be from the EBPV. It's on the turbo pedestal under the turbo on the passenger side. See the hole the rod is coming out of? Is yours leaking oil from there? (stuffing a digital camera down there and taking pictures is easier than trying to see it by leaning at just the right angle with a flashlight).



Yours will probably look something like this and need some cleaning up to figure out if it's leaking or not.



The P1211 doesn't mean the sensor is bad. It just means that there is not enough oil pressure in the rails to keep the PCM happy. Is your engine oil full since you have a leak now? Got a chip or tuner? Does the truck run or act differently when the light is set?

 

Yes, I have a DP tuner, but only ride with the 80 econ. Oil was a little low( not significately though), but now topped off. In my opinion the truck runs a little rougher with the light on. This might just be that its now winter season, and takes longer for it to worm up or my paranoia setting in about the light.

Should the light go off if the engine was working properly? It's stayed on since its turned on.

Thanks

 

The light will usually stay on for a few minutes and then turn itself off. Setting a P1211 with a DP is pretty common and nothing to worry about.

 

Ok, I finally got to use my new AE to narrow down the problem.

Read out says:

P1211 intake controller pressure high/lower than desired (engine running)
intake absolute pressure 40.7 in/hg
engine rpm 1986 r/min
vehicle speed 48mph.

I can only assume this iformation is from the time the light went on.

 

That really doesn't tell us much. We would need to know what the ICP psi and duty % was, along with throttle position % at the time the light was tripped, but as I said before, P1211 is pretty common on a chipped truck and nothing to worry about unless it starts affecting performance or the light just bugs you.

 

Ok. It was my first time trying the AE and thats all it gave me right off the bat. I still have to look indepth more on all what I can do and see with the AE.

I might just reset, and turn off the light. That way I can see if it will turn back on.

 

In reference to the CEL and the ICP code that my AE was reading. I started my truck today and the light never turned on. The last couple of days I have put my DP back to stock (which sucks) and now the light has gone away. This is wired. I have never had the code trip the computer before since I don't rag on my truck with the tuner.


Still haven't had enough time to check/track down the oil leak. thanks for the suggestion above. I think that might be it. If I can snag some more money my new turbo is going to be purchased and I will delete the EBPV.
