CODE #122,PEDAL POSITION SENSOR

1993 Chevrolet Astro • 6 cylinder Automatic • 87,000 miles

Ive determined that the problem with my 1993 chevy lumina van is the throttle pedal position sensor/switch A circuit low sensor is bad, where is this sensor located?

The TPS is on the throttle-body. The apv is a lumina not an astro. For that model year, neither one has a pedal position sensor. Both, Does have a throttle position sensor. I've never hear of that code number, you may have to double check? I could be wrong, haven't heard of Astro APV?
