Anyone know why this code appears? Truck loses power from this. It is an overvoltage in the M.A.P. sensor, or so it says. Not sure if just replacing the sensor will fix it (about 100 bucks) or if something else is just cauing the sensor to overvolt.

 

P0238 (M) Map Sensor Voltage Too High

MAP sensor voltage input above the maximum
acceptable voltage.

Do you think they're refering to the 5v reference signal from the computer or the signal back to the computer?

 

That, I guess, is the question. I'm trying to determine if replaceing the sensor is the solution or if I should look elsewhere.
