At lunch when I got in my truck the check engine light was on and it was running like a dog. Got the code read at auto zone and came up with P0273. He said it was a bad turbo boost sensor. After checking with the *********** to see if they have it I got in the truck and it was running fine. The light is still on because I have not cleared the computer. I tried searching, but the search seems screwed up tonight. Any ideas on this? Has this happened to anyone before?

 

are you sure that is the correct code? its not even listed that I can see

 

Im almost positive thats the code. I wrote it down straght from the code reader. Is there another code for the turbo boost sensor?

Edit, I could have written it down wrong, the code may be P0237 if that helps.

 

Po237 map sensor voltage too low

don t worry about it, sensors do go bad.

 

Thats kinda what I was thinking. Just making sure it wasnt anything more serious. Hopefully I can pick one up in the morning.

 

Next time you get the engine light on, no need to get codes scanned at parts store. Just cycle the key on/off/on/off/on (do not start engine), and the codes will show up in odometer.

 

Thanks for the tip.

I just changed the sensor with one thats used, but I know its good. I also had the code cleared by a buddy that works at a shop with a code reader. It was fine for about 5 miles and the the check engine light came back on and started running like *** again. It seems to come and go, one minute it runs fine the next its not getting any boost.

any other ideas?
could this have anything to do with the boost fooler on the truck? can they go bad?

By the way, I just went out and checked the code and got P1693.

 

Well I unhooked the boost fooler and it seems to be running fine. Now i deen to get the code cleared and see if it comes back. Where is the best place to get a boost fooler?

 

Was just told mine was bad code P0122.
