Hey my buddy(wimpy76) just called on his way to moab ,ut and told me he got a low boost code p0237.He wanted me to go on here and check to see what it might be.From everything I read it sounds lik a sensor by the turbo or the mapp sensor. If you go to his sig you will see he i running the aftermarket htt turbo so that sensor should be jumped .Anyway if you have any ideas let me. He was able to clear it with his smarty.

 

just hope the P0299 from the turbo doesnt appear. that will cause limp mode.

 

I get that code plus the MAF high voltage code together, but that is when I forget too plug the MAF in after removing intake.

Check the map connector, and MAF connector and see if that helps.

 

i think i got that one on the drive to san antonio, and i did go into limp mode. i thought something was very wrong because it had zero power. luckily i had my smarty with me to clear the code and no trouble since

thanks for everyones help.Bill siad his truck ran good after he cleared the code.

 

Thanks for everyones help I made it back from moab. But on the way home threw a code again and it was po299 and went into limp mode again. Can anybody tell me what it might be and how to fix it.

Bill

 

Also to add as soon as I clear the code I started back up and made it the rest of the way home with no more issues.

Bill

 

you are lucky to have a smarty to clear the code. talk to your turbo supplier for a fix.

I am surprised this problem does not happen more frequently.
