Customer Concern: The customer stated that the vehicle would not accelerate. Road tested the vehicle and it runs and drives fine. There is an Accelerator Pedal Position (APP) sensor 2 circuit code P2127.
1. Locate the APS sensor, located under the hood by the brake booster, and verify there is a good connection and 5-volts on the Green wire and the Red/Orange wire. Next, verify that the grounds are good on the Brown and Black/White wire. If the 5-volts and ground are good, then back probe the Pink wire for APS #2 and the White wire for APS #1 and both sensors should sweep together from about 0.5 volt to about 5 volts. Use a scope, if necessary, to see the signal drop out. If the signal drops out, replace the sensor.
