This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with a sensor that checks the air pressure going into a turbo or supercharger. It's like when you have a balloon and you're trying to see how full it is, but your gauge isn't working right.
The P2374 code is triggered when the engine control module (ECM) detects a malfunction in the circuit of the inlet pressure sensor for the turbocharger or supercharger.
The inlet pressure sensor B is responsible for measuring the pressure of the air entering the turbocharger or supercharger. This information is crucial for the ECM to adjust the air-fuel mixture and boost pressure appropriately. A fault in this sensor's circuit can lead to improper engine performance and efficiency.
• Check Engine Light illuminated
• Reduced engine performance
• Possible poor fuel economy
• Faulty inlet pressure sensor B
• Wiring issues such as shorts or open circuits
• Poor electrical connection to the sensor
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 air entering the engine, similar to a turbocharger but driven by the engine itself.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the inlet pressure sensor B for proper operation.
• Replace the faulty inlet pressure sensor B.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect and maintain the turbocharger system.
• Ensure all sensors and wiring are in good condition.
• Follow manufacturer service intervals.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have a professional diagnose the issue if you're unsure.
• Regular maintenance can prevent such issues.
Check with your vehicle manufacturer as sensor issues may be covered under powertrain warranty.
This code has been commonly associated with vehicles that have turbocharged engines and is often due to sensor wear or wiring issues.
Moderate – It's important to address this issue to avoid potential engine performance problems.
Driving with a malfunctioning sensor can lead to reduced engine performance and increased emissions.
• Engine running
• Turbocharger or supercharger engaged
The inlet pressure sensor B is typically located near the turbocharger or supercharger, often on the intake manifold.
Q: Can I drive with a P2374 code?
A: It's possible, but not recommended as it can affect engine performance and efficiency.
Q: How do I reset the Check Engine Light after fixing the issue?
A: Use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes.
