2006 T1N 158" High Top
Greetings Sprinter Community~
While traveling out to the Northern California Sprinter Campout (Thanks for a fantastic event Dale and all!), my T1N went into a low form of LHM.
Here are a few details:
No CEL, except *sometimes* when I restart the van (even without CEL -> van is in LHM within 5 minutes of clearing codes)
When the CEL does come on, a DAD reads the error as P2526-004, which is a 'right charge pressure positioner' or 'boost pressure regulator open circuit' code.
O2 sensor, Air intake sensor, Ambient temp sensor, turbo hoses, and turbo resonator have all be replaced recently and are properly connected and functioning as far as I can tell. Turbo actuator is not frozen, as I lubed it with Hi-temp lithium grease and can occasionally get boost and see the actuator move before the van goes into LHM.
I've got a Boost Pressure sensor on order from Europarts, and will chase electrical gremlins from the turbo actuator to the ECM to the ground at G202 in the coming weeks. Also FWIW: The van was in a fender bender with the previous owner, but because this error is relatively new, I suspect this isn't a direct result from the accident (perhaps the crash caused a short that took a year to finally appear and cause issues?).
In the meantime wanted to query the forum so see if I could get any other ideas. Any and all recommendations are appreciated
