This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a sensor in the car that checks the temperature of the turbocharger. It's like a thermometer that isn't working right.
The P2B92 code indicates that the Engine Control Module (ECM) has detected a problem with the temperature sensor circuit of the turbocharger or supercharger labeled 'B'. The sensor is not sending the expected range of signals.
The temperature sensor in question monitors the temperature of the turbocharger or supercharger to ensure it operates within the optimal range. If the sensor sends signals that are out of the expected range, the ECM triggers the P2B92 code. This could be due to a faulty sensor, wiring issues, or problems with the turbocharger itself.
• Check Engine Light is on
• Reduced engine performance
• Possible overheating
• Decreased fuel efficiency
• Faulty temperature sensor
• Wiring issues in the sensor circuit
• Malfunctioning turbocharger/supercharger
• Poor electrical connections
Turbocharger: A device that increases an engine's efficiency and power output by forcing extra air into the combustion chamber.
Supercharger: A device that increases the pressure of the air entering the engine to increase power output.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors of the temperature sensor.
• Test the sensor's resistance and voltage output.
• Check the turbocharger/supercharger for any physical damage.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Service or replace the turbocharger/supercharger if necessary.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Volkswagen Golf GTI
• Regularly inspect and maintain the turbocharger system.
• Ensure all sensors and wiring are in good condition.
• Perform routine engine diagnostics.
Sensor Issue
• Avoid heavy acceleration until the issue is fixed.
• Get the vehicle inspected by a professional mechanic.
• Monitor engine performance for any unusual behavior.
Check with the vehicle manufacturer for warranty coverage on engine sensors and turbocharger components.
This code has been reported in vehicles with turbocharged engines, particularly in models with higher mileage where sensor wear is more common.
Moderate – While the vehicle may still operate, reduced performance and potential overheating can lead to further damage.
Driving with a malfunctioning turbocharger can lead to engine damage and decreased safety. Address this issue promptly.
• Engine at operating temperature
• Vehicle stationary and idling
The temperature sensor is typically located near the turbocharger or supercharger, often on the intake or exhaust side.
Q: Can I drive with a P2B92 code?
A: It's not recommended to drive for long periods with this code, as it can lead to engine performance issues or damage.
Q: How do I reset the P2B92 code?
A: After fixing the issue, you can use an OBD-II scanner to clear the code. If the problem persists, the code will reappear.
