This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a sensor that helps the car's turbo or supercharger know how much extra power it's giving. It's like a broken thermometer that can't tell how hot it is.
The P25F2 code indicates an issue with the circuit of the Boost Sensor C, which is responsible for monitoring the boost pressure from the turbocharger or supercharger.
The Turbocharger/Supercharger Boost Sensor C is part of the engine's forced induction system, which increases the engine's efficiency and power output by forcing extra air into the combustion chamber. The sensor monitors the boost pressure and sends this data to the engine control module (ECM). If the ECM detects a problem with the sensor's circuit, such as an open or short circuit, it triggers the P25F2 code.
• Check Engine Light is on
• Reduced engine performance
• Poor acceleration
• Faulty Boost Sensor C
• Wiring issues in the sensor circuit
• Faulty ECM
Turbocharger: A device that increases an engine's efficiency and power output by forcing extra air into the combustion chamber.
Supercharger: A device similar to a turbocharger, but driven by the engine's crankshaft to increase air intake pressure.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the Boost Sensor C for proper operation.
• Replace the faulty Boost Sensor C.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram 1500
• Regularly inspect and maintain the turbocharger system.
• Ensure all sensors are clean and functioning.
• Perform regular diagnostic checks.
Sensor Issue
• Avoid heavy acceleration until the issue is resolved.
• Get a professional diagnosis to prevent further damage.
Check your vehicle's warranty to see if sensor issues are covered.
This code has been associated with turbocharger systems in modern vehicles, particularly those with complex forced induction setups.
Moderate – It should be addressed soon to avoid potential engine performance issues.
Driving with this code may lead to reduced engine performance and efficiency. It is advisable to address the issue to ensure safety and compliance with emissions regulations.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The Boost Sensor C is typically located near the turbocharger or supercharger, often on the intake manifold.
Q: Can I drive with a P25F2 code?
A: It's possible, but not recommended as it may lead to reduced performance and potential engine damage.
Q: How do I reset the P25F2 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is resolved, it should not return.
