Anyone know what this P0237 code means? Could it be related to the Edge box? Thanks!

237 = map sensor voltage too low. Probably something clogging your filter intake or a dirty filter. BTW, all of the codes are listed in the FAQ forum above.

P0237 Turbocharger Boost Pressure Sensor Low

got this code on my 05. I think it is related to my current problems with my quad-z which Quadzilla is working with me on.

Forgot to address this. The Edge obviously sits between the MAP sensor and the ECM, so if your connectors are loose or you just plain have a bad connection it could cause this code to appear. Also the Edge is your boost fooler, so if it's feeding bad info to the ECM it could cause this as well.



Fwiw my only experience with the 237 code was on a stock 03 with the airbox intake tract packed full of snow. Cleared the snow out so it could breathe again, and a few starts later the code cleared itself. So check the intake and the Edge connections at the MAP sensor.

Just had the same thing happen to me yesterday - while the engine was running I accidently unhooked the Edge and reconnected it. After that I got a P0237 code - thanks to autozone. I read up on the TDR and figured it was the MAP sensor - I just got done and fixed the problem. here is what I did:



Unhooked Edge Comp connector in back of unit, unplugged replacement map sensor plug and reinstalled factory harness, started truck 3 times (No Edge Comp). Next, used dielctric grease on Map harness fittings and plugged everything back together - started truck up - no CEL!!!! YMMV



Who would have known a $6 tube of goo could do so much?
