I have been getting this code for the map sensor high output voltage. Tried a new MAP sensor, cleaning throttle body and checking for vacuum leaks, all to no avail. Can drive at low speeds without throwing code, but under load (up a hill) at 45 mph or better the CEL shows up and the P0108 code is read. Anyone have any suggestions I might try? Thanks for much for any assistance.

 

Damn the pictures changed.

 

The cause and remedy of error code p0108 can be found in the hyperlink http://www.obd-codes.com/p0108

 

thank you very much for the link. I was able to diagnose and determine that the "new" MAP sensor was faulty and traded it for another. Car is back to normal now.
