Just noticed I asked for help in the wrong spot when I first posted the following.........going to include the same question here for some guidance in resolving a couple codes showing in a car:
Steve here. I replaced the MAP sensor over a month ago after getting a code for the sensor, car has run great for about 3,000 miles since. Today, engine idles fast, making initial shifting hard. Getting codes for P0106 and P0122............Map system performance, and TPS circuit low voltage. What do I do. Seemed replacing the MAP sensor did the trick before, hard to believe the new one went out, especially when getting another code for TPS circuit low voltage. I don't know where that sensor is yet, found the MAP sensor by replacement part number matching what was in the car.
Going to mention, just in case it might somehow matter, that earlier today the car was hit by a bird just below the right headlight, small piece of front bumper cover broke just below the headlight.
I would appreciate some direction in resolving the problem.
Sorry I am tardy on this one.
Sounds like you have a connection problem at the MAP sensor or a problem with the 5V reference.
Is this car still acting up?
Give a tug on each wire at the MAP sensor, one might be broken inside the insulation. When you replaced the sensor you "fixed" the problem temporarily.
The insulation will stretch if the wire is broken.
You can get a "pigtail" for the MAP sensor from an AC Delco supplier.
