Code P0507 2016 Chevrolet Silverado 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.

Frequently Asked Questions about P0507 2016 Chevrolet Silverado Code

1. What does the OBDII code P0507 mean on a 2016 Chevrolet Silverado?

P0507 indicates that the engine control module (ECM) has detected an idle speed that is higher than the manufacturerâ€™s specified range.

2. What are the common symptoms of code P0507 on a 2016 Chevy Silverado?

Symptoms may include a high or fluctuating idle speed, poor fuel economy, and potentially a check engine light.

3. What causes the P0507 code to appear on a 2016 Chevrolet Silverado?

Common causes include a dirty or faulty throttle body, vacuum leaks, a malfunctioning idle air control (IAC) valve, or issues with the PCV system.

4. Can a vacuum leak trigger the P0507 code on my 2016 Silverado?

Yes, a vacuum leak can cause the idle speed to rise and trigger the P0507 code.

5. How do I fix the P0507 code on a 2016 Chevy Silverado?

Repairs may include cleaning the throttle body, inspecting and fixing vacuum leaks, replacing a faulty IAC valve, or reprogramming the ECM if necessary.

6. Is it safe to drive my 2016 Silverado with the P0507 code?

While the vehicle may still be drivable, itâ€™s not recommended as the high idle speed can cause further damage to the engine or catalytic converter over time.

7. Can a dirty throttle body cause the P0507 code on a 2016 Chevrolet Silverado?

Yes, a dirty throttle body can restrict airflow and cause the ECM to miscalculate idle speed, leading to the P0507 code.

8. Will resetting the ECM clear the P0507 code on my 2016 Silverado?

Resetting the ECM may temporarily clear the code, but the underlying issue must be fixed to prevent the code from returning.

9. How much does it cost to fix the P0507 code on a 2016 Chevy Silverado?

Costs vary based on the cause, but cleaning the throttle body typically costs $50-$150, while replacing components like the IAC valve can cost $150-$300 or more.

10. Can a faulty PCV valve cause the P0507 code on my 2016 Silverado?
