Code P0507 2014 GMC Sierra Description

The Engine Control Module (ECM) is the control center for the Throttle Actuator Control (TAC) system. The ECM determines the driver's intent based on input from the accelerator pedal position sensors, then calculates the appropriate throttle response based on the throttle position sensors. The Direct Current (DC) motor, located in the Throttle Body Assembly, drives the throttle blade. In order to decrease idle speed, along with spark and fuel delivery changes the ECM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the ECM commands the throttle plate open allowing more air to pass the throttle plate. The Diagnostic Trouble Code (DTC) will be set when the actual idle speed is approximately 188 RPM greater than the desired idle speed.

Code Tech Notes

If there are no intake leaks, clean the throttle body, adjust the engine idle, and clear the engine code. If the code persists you must replace the Electric Throttle Actuator Motor (Located in the Throttle Body Assembly).

The Engine Control Module (ECM) learns the idle position of the throttle plate to ensure the correct idle. Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position. The idle may be unstable or a DTC may be set if the throttle position is not learned.

1. What are the common symptoms of OBDII code P0507 on a 2014 GMC Sierra?

- Common symptoms include high idle speed, rough idling, stalling at stops, and the Check Engine light illuminated on the dashboard.

2. What can cause the OBDII code P0507 indicating high idle speed in a 2014 GMC Sierra?

- The high idle speed in a 2014 GMC Sierra can be caused by a dirty or faulty idle air control valve, a vacuum leak, a malfunctioning throttle body, or issues with the engine's air intake system.

3. How can I diagnose the OBDII code P0507 on my 2014 GMC Sierra?

- To diagnose the P0507 code, you can use an OBDII scanner to read the code and check for any related codes. Additionally, you can inspect the idle air control valve, throttle body, and vacuum lines for any signs of damage or wear.

4. Can a dirty throttle body cause the OBDII code P0507 in a 2014 GMC Sierra?

- Yes, a dirty throttle body can restrict airflow and disrupt the engine's idle speed control, potentially triggering the P0507 code in a 2014 GMC Sierra.

5. What are some repair tips for addressing the OBDII code P0507 on a 2014 GMC Sierra?

- Repair tips include cleaning or replacing the idle air control valve, cleaning the throttle body, checking and repairing any vacuum leaks, and ensuring the air intake system is free from obstructions.

6. Is it safe to continue driving a 2014 GMC Sierra with the OBDII code P0507 indicating high idle speed?

- It is not recommended to drive a vehicle with the P0507 code for an extended period, as it can lead to poor fuel economy, engine performance issues, and potential damage to engine components.

7. Can a faulty oxygen sensor trigger the OBDII code P0507 on a 2014 GMC Sierra?

- While a faulty oxygen sensor is not a direct cause of the P0507 code, it can contribute to poor engine performance, which may indirectly lead to high idle speed and trigger the code.

8. How much does it typically cost to repair the OBDII code P0507 on a 2014 GMC Sierra?

- Repair costs for the P0507 code can vary depending on the underlying cause and the labor rates in your area. It is advisable to consult with a mechanic for an accurate estimate.

9. Will disconnecting the battery reset the OBDII code P0507 on a 2014 GMC Sierra?
