This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a sensor that checks the air pressure going into the turbocharger or supercharger. It's like if a balloon pump wasn't working right and couldn't tell how much air was going into the balloon.
The P2375 code is triggered when the engine control module (ECM) detects a problem with the readings from the turbocharger/supercharger inlet pressure sensor, specifically the 'B' circuit. This could mean the sensor is not working properly or the readings are outside the expected range.
The turbocharger/supercharger inlet pressure sensor measures the pressure of the air entering the turbocharger or supercharger. The ECM uses this data to adjust the air-fuel mixture and boost pressure. If the sensor's output is not within the expected range, the ECM will set the P2375 code.
• Check Engine Light is on
• Reduced engine performance
• Poor acceleration
• Faulty turbocharger/supercharger inlet pressure sensor
• 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 that increases the pressure or density of air supplied to an internal combustion engine.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the sensor with a multimeter to ensure it is functioning correctly.
• Replace the faulty pressure sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect and maintain the turbocharger system.
• Ensure all sensors are clean and free from debris.
• Check wiring and connectors for wear and tear.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Regular maintenance can prevent such issues.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
P2375 is a relatively uncommon code, typically associated with vehicles that have turbocharged or supercharged engines.
Moderate – While the vehicle may still be drivable, performance issues can worsen over time.
Ignoring this code can lead to increased emissions and potential damage to the engine or turbocharger/supercharger system.
• Engine running at operating temperature
• Varying throttle conditions to test sensor response
The turbocharger/supercharger inlet pressure sensor is typically located near the turbocharger or supercharger, often mounted on the intake manifold or piping.
Q: Can I drive with a P2375 code?
A: It's possible to drive with this code, but it's not recommended as it can lead to reduced performance and increased emissions.
Q: How can I prevent this code from appearing?
A: Regular maintenance and inspections of the turbocharger system and sensors can help prevent this code.
