P0237?

[SShafranko]

My truck is in limp mode, spit out p0237 and reads Turbo Boost Sensor Circuit Low Input. No boost reading at all. Is my MAP sensor toast?

I would say yes, your MAP sensor is shot. Unless your turbo is shot and not putting out any pressure. Also check all the boost plumbing to be sure nothing is disconnected.

And check to be sure the wastegate isn't stuck wide open.

Installed the new map sensor and the code is gone but i still don't have any boost. Going to look it over in a few minutes to see if it is anything visible. Any ideas? If my turbo is toast how can i test it? Could my wastegate be stuck open?

All threads found on this subject are not finished. Wastegate fuse is ok. Checked intercooler and hoses everything is ok. Going to the garage to take apart and take a better look. Hard to believe noone has any ideas! thanks for the replies.

Is the turbo spooling?

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. TY for all replies.
