I limped the truck home last night going about 40 to 45. Even lower on bigger hills. Ran a code reader today at auto zone. Its throwing a P0237 2 times. Showing a Turbo sensor circuit A low input. I need to drive it to work tonight. How is this fixed and where do i look. I am just glad i could get it to auto zone to get the code reader on it. I was fearing the worst when I was getting some dead pedal. But i knew the fass was working fine and fp wasnt bad. So i had no idea what the deal was. Any help would be appreciated.

P0237 2x
Turbo Sensor Circuit A Low Input

 

POSSIBLE CAUSES


"Boost pressure test" did not pass
5-volt supply voltage low code present
No possible causes remaining
5-volt supply circuit open
MAP sensor signal circuit short to ground
MAP sensor signal circuit short to sensor ground circuit
Wiring harness intermittent defect
Wiring harness observable defect
Engine control module defective
MAP sensor defective


I would say your MAP sensor crapped the bed

 

Try removing the Adrenaline and see how it does.

unplug and replug the map and maybe try a different tune

 

already did. still the same stuff. almost feels like it wont build a lot of boost. but that was the code i got so im sure its something to do with that right? Could it be the sensor itself?

 

Really does sound like the MAP sensor

 

when i had mine when i cleared the code everything was fine but that was also after i had put new boots on that I bought from luke as i discovered some leaks but it could be a map taking a crap

 

hmmm. ill def check all my boots and lines. although last time i had a leak in a boot i was smoking like crazy and still had a little bit of power, just couldnt build boost. Also ill try here soon to check my map sensor. thanks for continuing thoughts/ideas. prolly be a few days until i can get to it now. so if any other ideas come up let me know....

 

i have same code and im pretty sure map sensor i cleaned mine and it runs better but i still need a new one.

 

Any luck??
