Default 99 cummins engine light

throw a code p0237

the code days the map sensor has a low voltage.
dealer says theres no part number for map sensor.
code also states that the ecm has detected that intake air pressure below a calibrated value to long.

truck still runs good. still smokes tires through 3rd gear. stilling boosting around 42 pounds.

it also states that it could be a turbo boost sensor. but thats for a ford or gm product. not a cummins product.
