P1514 Chevrolet Code - Throttle Actuator Control System Mass Air Flow Performance
Quick Answer
The Throttle Actuator Control (TAC) system uses vehicle electronics and components to calculate and control the position of the throttle blade. Common causes include Faulty Throttle Actuator Control (TAC), Throttle Actuator Control (TAC) harness is open or shorted, Throttle Actuator Control (TAC) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1514 Chevrolet Description
The TAC system components include, but are not limited to the following:
- The accelerator pedal position (APP) sensors
- The throttle body
- The Powertrain Control Module (PCM)
Each of these components interface together to ensure accurate calculations and control of the throttle position (TP).
<b>Throttle Body Assembly</b>
The throttle body for the throttle actuator control (TAC) system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the throttle position (TP) sensor. The TP sensor is mounted in the throttle body assembly. The TP sensor is 2 individual TP sensors within the throttle body assembly. Two separate signal, low reference, and 5-volt reference circuits are used to connect the TP sensors and the Powertrain Control Module (PCM). TP sensor 2 signal voltage increases as the throttle opens. TP sensor 1 signal voltage decreases as the throttle opens.

- Faulty Throttle Actuator Control (TAC)
- Throttle Actuator Control (TAC) harness is open or shorted
- Throttle Actuator Control (TAC) circuit poor electrical connection
