How do I fix Code P1516?
Make sure you check the ground wire from the TAC harness to the back of the engine block passenger side. In many cases, this could be the culprit of the code. Also in some cases, the throttle body plate could be sticking because of dirt. You can try cleaning the throttle body before replacing any parts.
What does Code P1516 mean?
throttle position sensor
The code P1516 is is for the throttle position sensor. It looks like the car’s computer is putting the engine in “failsafe mode” to prevent the car from being driven much further.
What causes p1516 GMC throttle actuator control module to fail?
P1516 GMC Possible Causes Faulty Throttle Actuator Control (TAC) module Throttle Actuator Control (TAC) module harness is open or shorted Throttle Actuator Control (TAC) module circuit poor electrical connection Check Throttle Actuator Control (TAC) module connector for water Binding or bent throttle plate-failed throttle body
What does the code p1516 mean on a Chevy?
P1516 CHEVROLET Meaning The Engine Control Module (ECM) is the control center for the Throttle Actuator Control (TAC) system. The ECMdetermines the drivers intent and then calculates the appropriate throttle response. The ECMachieves throttle positioning by providing a pulse width modulated voltage to the TAC motor.
What is the throttle actuator control module ( TAC )?
P1516 Gmc Description. The Engine Control Module (ECM) is the control center for the Throttle Actuator Control (TAC) system. The ECM determines the drivers intent and then calculates the appropriate throttle response. The ECM achieves throttle positioning by providing a pulse width modulated voltage to the TAC motor.
What to do if the p1516 code returns?
If the P1516 code does return, further testing will be required. We will need to test the Throttle Actuator Position Sensor (TAPS). The easiest way of doing this is to monitor the voltage signals from the Throttle Actuator Position Sensor (TAPS) as you drive the vehicle down the road as it is acting up.
