Code P0453 2017 Chevrolet Silverado Description
The P0453 diagnostic trouble code (DTC) on a 2017 Chevrolet Silverado indicates a potential issue with the Fuel Tank Pressure Sensor Circuit registering a high voltage. The fuel tank pressure sensor measures the pressure inside the fuel tank and sends this information to the vehicle's engine control module (ECM). A high voltage reading from the sensor can indicate a problem with the sensor itself or issues with the wiring or connectors in the circuit.
Common Causes of P0453 2017 Chevrolet Silverado
- Faulty fuel tank pressure sensor
- Damaged or corroded wiring in the sensor circuit
- Loose or poor connections at the sensor or ECM
- Fuel tank pressure sensor circuit short to power
- ECM malfunction
Symptoms of P0453 2017 Chevrolet Silverado
- Check engine light illuminated on the dashboard
- Decreased fuel efficiency
- Rough idling or stalling
- Failed emissions test
- Difficulty starting the vehicle
How to Fix P0453 2017 Chevrolet Silverado
- Begin by diagnosing the issue using a scan tool to confirm the P0453 code and pinpoint the source of the problem.
- Inspect the fuel tank pressure sensor, wiring, and connectors for any signs of damage or corrosion. Replace any faulty components.
- Clear the DTC and reset the ECM to see if the code returns after repairs have been made.
- Perform a road test to ensure that the repair has resolved the issue and that the symptoms associated with the P0453 code have been eliminated.
- If the code persists, further diagnostics may be required to identify any underlying issues with the fuel tank pressure sensor circuit.

Frequently Asked Questions about P0453 2017 Chevrolet Silverado Code
1. What does OBDII code P0453 mean on a 2017 Chevrolet Silverado?
P0453 indicates that the fuel tank pressure sensor is reporting a voltage signal higher than the expected range, suggesting an issue in the EVAP (Evaporative Emission Control) system.
2. What are the common symptoms of code P0453 in a 2017 Chevrolet Silverado?
Symptoms may include an illuminated check engine light, difficulty refueling due to pressure buildup, increased fuel odor, and potentially reduced fuel efficiency.
3. What causes the P0453 code on a 2017 Chevrolet Silverado?
Common causes include a faulty fuel tank pressure sensor, damaged wiring or connectors in the sensor circuit, or a malfunctioning EVAP system component.
4. Can a loose gas cap trigger the P0453 code?
A loose or damaged gas cap is unlikely to trigger P0453 directly but could contribute to EVAP system issues. It’s still good practice to check the gas cap when diagnosing EVAP-related codes.
5. How do I diagnose the P0453 code on my 2017 Chevrolet Silverado?
Start by inspecting the fuel tank pressure sensor and its wiring for damage. Use a multimeter to test the sensor's voltage output and compare it to manufacturer specifications.
6. How do I fix the P0453 code on a 2017 Chevrolet Silverado?
Repairs may involve replacing a faulty fuel tank pressure sensor, repairing damaged wiring or connectors, or addressing leaks or blockages in the EVAP system.
7. Is it safe to drive my 2017 Chevrolet Silverado with the P0453 code?
While the truck may still be drivable, ignoring this code can lead to worsening EVAP system issues, higher emissions, or difficulty passing emissions tests.
8. How much does it cost to fix the P0453 code on a 2017 Chevrolet Silverado?
Repair costs can vary but typically range from $150 to $400, depending on whether the issue is a faulty sensor, wiring repair, or another EVAP-related problem.
9. Can a bad fuel tank pressure sensor cause other problems?
Yes, a bad sensor can lead to inaccurate fuel vapor pressure readings, potentially affecting the EVAP system's operation and triggering additional diagnostic trouble codes.
10. Will clearing the code P0453 fix the problem on my 2017 Chevrolet Silverado?
Clearing the code will turn off the check engine light temporarily but won’t resolve the underlying issue. The code will likely return until the root cause is addressed.
