Code P0223 2017 Chevrolet Silverado Description

The Throttle Body Assembly contains a contact-less inductive throttle position sensing element that is managed by a customized integrated circuit. The throttle position sensor is mounted within the throttle body assembly and is not serviceable. The Engine Control Module (ECM) supplies the throttle body with a 5 V reference circuit, a low reference circuit. The asynchronous signal means communication is only going from the throttle body to the ECM. The throttle body cannot receive data from the ECM over the signal/serial data circuit. The throttle position sensor provides a signal voltage that changes relative to throttle blade angle. The throttle position sensor information is transmitted between the throttle body and the ECM on the signal/serial data circuit. The ECM decodes the serial data signal and is used as voltages for throttle position sensor 1 and 2. The Diagnostic Trouble Code (DTC) will be set when the ECM detects the throttle position sensor 2 signal voltage is greater than 4.6 V for greater than 1 s.

Frequently Asked Questions about P0223 2017 Chevrolet Silverado Code

1. What does the OBDII code P0223 mean on a 2017 Chevrolet Silverado?

P0223 indicates a high voltage issue in the Throttle Position Sensor (TPS) 2 circuit, which monitors the throttle's position for proper engine performance.

2. What are common symptoms of a P0223 code on a 2017 Silverado?

Symptoms may include reduced engine power, erratic throttle response, stalling, difficulty accelerating, or the activation of the "Reduced Engine Power" warning.

3. What causes the P0223 code to appear on a 2017 Chevrolet Silverado?

Possible causes include a faulty TPS sensor, damaged wiring or connectors, a short circuit, or issues with the Engine Control Module (ECM).

4. Can I drive my 2017 Silverado with a P0223 code?

Driving with a P0223 code is not recommended as it can lead to reduced engine performance and potential safety risks due to throttle control issues.

5. How is the P0223 code diagnosed on a 2017 Chevrolet Silverado?

A mechanic will use an OBDII scanner to confirm the code, inspect the TPS sensor and its wiring for damage, and test the sensor's voltage readings for abnormalities.

6. How can I fix the P0223 code on my 2017 Silverado?

Repairs may include replacing the TPS sensor, repairing or replacing damaged wiring, cleaning corroded connections, or reprogramming the ECM if necessary.

7. How much does it cost to repair a P0223 code on a 2017 Chevrolet Silverado?

Repair costs vary but typically range from $100 to $400, depending on whether only the sensor or additional components like wiring or the ECM need replacement.

8. Can a dirty throttle body cause a P0223 code on a 2017 Silverado?

While a dirty throttle body is not a direct cause, it can contribute to throttle-related issues, so cleaning it during diagnostics may help resolve related problems.

9. Does the P0223 code on a 2017 Silverado always mean the TPS sensor is bad?

No, the issue could also stem from damaged wiring, corroded connectors, or a malfunctioning ECM, so thorough diagnostics are essential.

10. Will clearing the P0223 code fix the problem on my 2017 Silverado?

Clearing the code without addressing the underlying issue will not fix the problem, and the code is likely to return. Proper diagnosis and repair are necessary.
