P0107 code help and dealership story
Short questions first:
What exactly causes the P0107 (Barometric pressure sensor circuit low input)code to be set? I assume a barometric sensor? If so, can somebody point me where to find that sensor?
I had my truck in the dealership today to have the water pump replaced. They called me and asked if I wanted them to check out the "Service Engine Soon" light. This stunned me because I've owned this truck for a year now with no problems and no codes all the way up until last night when I dropped it off for the water pump for replacement today. I told them to not do anything about it since I was very suspicious that it would suddenly throw a code while at the dealer. When I picked up the truck I asked about the light and he said the tech said it went off about half way through the test drive and didnt come back on.
I drove it home with no light and then pulled the P0107 code which is a low input on the barametric sensor input. I cleared the code and will watch it closely to see if it sets it again.
Here's my conspiracy theory: I bought the water pump at Powerstrokeshop.com and had my local dealer do the work for $130 (pretty reasonable). Since its a low voltage code I wonder if it was unplugged to set the code and a way for them to get at least $40 more for diagnostics and a way for them to make a few extra bucks for the lost parts revenue. Possibility? Sure, but I hope they wouldnt stoop that low.
In any case, I need to know where to locate this sensor just in case it really is going out on me or possibly has a loose plug.
