check engine light came on last night while driving computer is throwing P0122 Throttle Position (TP) Sensor Circuit Low Voltage would this be the sendor or the wiring going to the sensor

forget to add 1997 Z24 5speed and i changed the sensor about 3 months ago

Why did you change the sensor 3 months ago?

Did the light go away after you replaced it before?

Normally I would say the sensor but the life span of these is pretty long. To have 2 go bad in 4 months points me toward the wiring harness or other issue.

check the ground for that sensor.

and all the rest.

i cant remeber the reason behind changing it a few months ago i think it was cause my throttle was tripping out a little it was better after i changed it but it started to act up again over the last couple of days this was the first time the check engine light came on, i got to work that night and shut the car off and the light hasen't come on since but i will check all of the wiring thanks for the help
