When is the p2138 Chevrolet engine light detected?
Most auto repairs shops charge between $75 and $150 per hour. When is the P2138 CHEVROLET code detected? The Accelerator Pedal Position (APP) sensor is made up of 2 sensors that are housed inside one assembly. The Engine Control Module (ECM) supplies a separate 5-volt reference circuit and a low reference circuit for each of the sensors.
What does reduced power code p2138 stand for?

What is the p2138 code on a throttle body?
Photo of a throttle body, throttle body position (TPS) sensor is the black part to the lower right: The computer monitors the correlation of both voltages. When both voltages agree, the system is functioning properly. When they deviate for two seconds, the code P2138 is set indicating a malfunction somewhere in the system.
