Code P0453 2017 GMC Sierra Description
The P0453 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a problem with the fuel tank pressure sensor circuit registering a high voltage. This sensor is responsible for monitoring the pressure inside the fuel tank and sending this information to the engine control module (ECM). When the voltage detected by the sensor is higher than expected, it triggers the P0453 code.
Common Causes of P0453 2017 GMC Sierra
- Faulty fuel tank pressure sensor
- Damaged wiring or connectors in the sensor circuit
- ECM malfunction
- Evaporative emissions system leak
- Fuel cap not sealing properly
Symptoms of P0453 2017 GMC Sierra
- Check engine light illuminated
- Decreased fuel efficiency
- Rough idling or stalling
- Strong fuel odor near the vehicle
- Difficulty starting the engine
How to Fix P0453 2017 GMC Sierra
- Use an OBD-II scanner to confirm the P0453 code and diagnose the issue.
- Inspect the fuel tank pressure sensor, wiring, and connectors for any damage or corrosion.
- Test the sensor's voltage output and compare it to specifications to determine if it is faulty.
- Replace the fuel tank pressure sensor if it is found to be defective.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0453 2017 GMC Sierra
The typical repair costs for addressing a P0453 code on a 2017 GMC Sierra can range from $150 to $400, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that diagnosis time and labor rates at auto repair shops can vary, so it's advisable to check local rates for a more accurate estimate. Additionally, factors such as location, vehicle make and model, and engine type can influence repair costs.

Frequently Asked Questions about P0453 2017 GMC Sierra Code
1. What does code P0453 mean on a 2017 GMC Sierra?
Code P0453 indicates that the Fuel Tank Pressure Sensor Circuit is reading a voltage higher than expected, which can affect the vehicle's evaporative emissions system.
2. What are the common symptoms of P0453 on a 2017 GMC Sierra?
Symptoms may include an illuminated Check Engine Light, poor fuel efficiency, difficulty refueling, or a noticeable fuel odor around the vehicle.
3. What causes the P0453 code to appear on a 2017 GMC Sierra?
Common causes include a faulty fuel tank pressure sensor, damaged wiring or connectors in the sensor circuit, or a problem with the EVAP system, such as a clogged vent line.
4. Can I drive my 2017 GMC Sierra with a P0453 code?
While the vehicle may remain drivable, it’s recommended to address the issue promptly as it can affect emissions and fuel economy, and may lead to other problems if left unresolved.
5. How do I troubleshoot a P0453 code on a 2017 GMC Sierra?
Start by checking the fuel tank pressure sensor and its wiring for damage or loose connections. Use a multimeter to test the sensor's output voltage and verify it is within the expected range.
6. How do I fix the P0453 code on a 2017 GMC Sierra?
Repairs might include replacing the fuel tank pressure sensor, repairing or replacing damaged wiring, or addressing issues in the EVAP system, such as clearing blockages in vent lines.
7. How much does it cost to fix a P0453 code on a 2017 GMC Sierra?
The cost can vary but typically ranges from $150 to $400, depending on whether you replace the fuel tank pressure sensor or repair wiring issues.
8. Can a loose gas cap cause a P0453 code on a 2017 GMC Sierra?
A loose gas cap is unlikely to cause a P0453 code, as this code specifically relates to high voltage in the fuel tank pressure sensor circuit, not a general EVAP system leak.
9. Does clearing the P0453 code fix the issue on a 2017 GMC Sierra?
Clearing the code will turn off the Check Engine Light temporarily, but it won’t resolve the underlying problem. The code will likely return if the issue isn’t properly diagnosed and repaired.
10. Can a failing ECM cause a P0453 code on a 2017 GMC Sierra?
While rare, a failing Engine Control Module (ECM) could potentially cause incorrect voltage readings in the fuel tank pressure sensor circuit. However, this is usually considered only after other potential causes are ruled out.
