Dmax limp mode, fuel rail pressure too low - Anyone else?
A few weeks back I went on a working trip that involved one of our major mountain passes.
It was hot out, I'm towing my 27' TT with my D/A dually and I no sooner hit the beginning of the Coquihalla Highway, a very steep mountain pass, and my truck suddenly lost power, check engine light came on and it went into limp mode. Argh! Won't rev over 2000 RPM. I limped it all the way to Kamloops, some hundred miles away. I stopped for fuel, then carried on. I stopped at a store for some supplies and when I came out and started it up, check engine light was out and the truck ran normal again.
I went another hundred miles or so, did my work and headed home, everything ok. As soon as I got back to Kamloops and hit the big hill again, same thing happened. I got part way up a long hill in limp mode, turned around, found a dealer and had them read the code.
P0087 - Fuel rail - pressure too low. They reset it and I went on my way home but the light came back on right away.
I limped all the way home and when I got out of the mountains and on the flats at the coast again, problem went away. Dropped the TT at storage and the issue never came back again.
Took truck in for service, oil change and had them put a fuel filter on it. Hopefully this makes a difference. Old one had a lot of miles on it.
Fast forward to last weekend - grabbed the TT and headed to BC's Okanogan Valley to take a couple of my grandsons camping. Shortly into the mountains on Hwy 3 up a long hill, same scenario.
This time I had my code reader with me and I pulled over, hooked it up and erased the code. From there on I made sure I used manual mode, kept the revs up and didn't labor the engine too much. It happened one more time before I reached Penticton, our destination.
Had a great weekend with the grandsons and headed home, driving cautiously. No problems on the way home, even up a long major grade out of Princeton on Hwy 3.
This Friday I am heading up to BC's Cariboo region for the Labor Day long weekend. I am concerned about this issue. I don't have time to take it to the dealership for their expensive "throw all new parts at it" attitude.
Anyone else have this problem?
Any ideas on the cause of it?
Any suggestions?
It's a real pain going up a major hill at 20MPH having all the big rigs passing me!
