My truck will intermittently give me a P237 code. Its intermittent, nothing repetative about it. First time was about 6 months ago. Went away for 2 or 3 months and came back. It lasts for 1-3 days then goes away. This time it came back after about 3 weeks. The discription of the code makes no sense to me, something about low voltage output from the turbo.

 

this is what it means:

P0237
MAP Sensor Voltage Too Low
