Archived No Boost

[SShafranko]

Truck gave me code p0237 (low turbo boost voltage). I changed the MAP sensor and it is not giving me a code anymore, but still not boosting. Going to check all hoses now. Could it be my wastegate stuck open? Turbo? Help!

Wastegate fuse is good. Hoses and intercooler looks ok. Going to the garage to take everything apart. Can't believe noones anwsering this thread!

Found the problem!!! The boost fooling part of the EDGE is burnt out? When it shorted or whatever it did it also toasted my map sensor. I replaced the Map sensor and plugged it back in piggy backed with the Edge. Same result execpt it did not shoot out the trouble code anymore. So my map sensor must have been bad since it was shooting the p0237 code before i replaced it on every start up. After replacing the Map still no boost. I checked all hoses, IC and the Wategate and everything was perfect. Finally i decided to unplug the Map sensor and plug it back in without the Edge one more time and wala! Runs like new. I unplugged the Edge from the OBD port and left the truck running stock until i figure out the next step.



Anyway the problem is within the Edge itself. Hope this helps someone.

I have a similiar problem. An under load intermittent no/low boost but with a P1693 DTC showing. No engine trouble light. No air leaks found. Runs good with good power. Removed Edge EZ, same problem running stock.
