Hey all. We are currently on a road trip in Colorado and I'm having some problems with the turbo on my van. If I get on a long climb the turbo will quit building boost. I have to get out my torque app and reset the ecu. It doesn't throw a light, but I do see some codes in memory. P2135, P2136, which relate to the tps a/b and a/c voltage correlation, p1482 which says small leak detection in the heater pump circuit, which I don't have a clue what that is, and P2359 which I don't have a definition for. Each time it cuts out I'm in a high boost situation. It has done it while in cruise and while not using cruise control. Last night it did it a couple of times while climbing some grades near Vail pass, Colorado once after passing a big rig, then I had to pull on the shoulder and let him pass me back. I'm sure he was cussing me. Any hints to what I need to look at? Anyone near Loveland Colorado with a DAD or other tester? We are headed back to NC tonight or tomorrow and it would be nice to not have to worry about the turbo cutout on the way home. My cell is 828 289 7781 if you are near by. Thx!!!
First check what ambient temperature you are showing on the info panel, if it seems wildly out you may have an ambient temp correlation fault with the same unit giving intake sensor PCM info located on the air cleaner cover. There is a Dodge bulletin about loss of boost due to this issue and no mil lamp illumination fault. It gets hidden in instrument panel faults
Also an over boost fault can be attributed to that mentioned sensor on the air cleaner cover or in fact the boost sensor itself which is mounted in the turbo feed hose drivers side.
We often get folks from the "lowlands" with the same problems and the only way to run it down is smoke the intake system with pressurized theatrical smoke or do a stall test and raise the turbo blow pressure and see if the system will leak and blow the resonator seams apart.
If that looks OK then its sensor check time!
Info the 2005 TIN model seems to be very sensitive to air intake temp sensor faults and it has been superseded about three times.
Up there in Loveland you should be able to find an Independent shop with a Snap On basic scanner and Euro comms cable with a Dodge program. Using comms keys S17 for "power pack" , S20 for ABS, and S4 for instrument panel it should be easy to run down.
Snap on Verus Pro does auto scan--just plug 'n play then read!
By the way the Sprinter is found at the bottom of the selection list on Dodge programs second page when using a Snap on Solus Pro!
If you find a shop with the tool up there and they are unsure you can always call me and I can run the main points by them.

PS it can't be all bad! Take heart!
I had one in the shop last week with a no boost----Turned out to be a totally seized turbine--spendy job!
