P148F 2022 Chevrolet Silverado Code - EVAP Purge Pump Voltage Sensor High Voltage
Quick Answer
The P148F diagnostic trouble code (DTC) for the 2022 Chevrolet Silverado indicates a problem with the EVAP (Evaporative Emission Control) purge pump voltage sensor reading high voltage. Common causes include Faulty Purge Pump Voltage Sensor: The sensor responsible for measuring the voltage of the purge pump may be malfunctioning, leading to erroneous readings, Wiring Issues: Corroded, damaged, or loose wiring connections between the sensor and the engine control module (ECM) can cause high voltage readings, Purge Pump Failure: A failing or faulty purge pump can also trigger the P148F code as it may not be functioning properly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P148F 2022 Chevrolet Silverado Description
The P148F diagnostic trouble code (DTC) for the 2022 Chevrolet Silverado indicates a problem with the EVAP (Evaporative Emission Control) purge pump voltage sensor reading high voltage. The EVAP system is responsible for capturing and storing fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. The purge pump is a crucial component of this system, as it controls the flow of vapors into the engine for combustion.
Common Causes of P148F 2022 Chevrolet Silverado
- Faulty Purge Pump Voltage Sensor: The sensor responsible for measuring the voltage of the purge pump may be malfunctioning, leading to erroneous readings.
- Wiring Issues: Corroded, damaged, or loose wiring connections between the sensor and the engine control module (ECM) can cause high voltage readings.
- Purge Pump Failure: A failing or faulty purge pump can also trigger the P148F code as it may not be functioning properly.
- ECM Malfunction: In some cases, a malfunctioning ECM may be sending incorrect signals to the purge pump voltage sensor, causing it to read high voltage.
Symptoms of P148F 2022 Chevrolet Silverado
- Check Engine Light: The most obvious symptom of the P148F code is the illumination of the check engine light on the dashboard.
- Decreased Fuel Efficiency: A malfunctioning EVAP system can lead to poor fuel economy as fuel vapors may not be efficiently recycled back into the engine.
- Rough Idle: A high voltage reading from the purge pump sensor can cause irregular engine idle or stalling.
- Strong Fuel Odor: If fuel vapors are not properly captured and recycled, you may notice a strong smell of gasoline around the vehicle.
How to Fix P148F 2022 Chevrolet Silverado
- Diagnose the Issue: Use an OBD-II scanner to retrieve the specific DTC and pinpoint the source of the problem.
- Inspect Wiring: Check the wiring harness connecting the purge pump voltage sensor to the ECM for any signs of damage or corrosion. Repair or replace as necessary.
- Test Purge Pump: Test the purge pump to ensure it is functioning properly. Replace if it is found to be faulty.
- Replace Purge Pump Voltage Sensor: If the sensor is determined to be the cause of the high voltage reading, replace it with a new one.
- Clear Codes and Test Drive: Clear the DTC from the ECM memory, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P148F 2022 Chevrolet Silverado
The cost of repairing a P148F code on a 2022 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, replacing a purge pump voltage sensor can cost between $50 to $150, while a new purge pump itself can range from $100 to $300. The labor costs for this repair can add an additional $100 to $200, bringing the total repair cost to approximately $250 to $500. However, it is important to note that these estimates are rough averages, and actual costs can vary based on the location, dealership or independent shop rates, and any additional parts that may need replacement. It is recommended to consult with a certified mechanic or dealership for a more accurate cost estimate.
