This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a signal from a sensor that measures pressure in the turbocharger system, and the signal is higher than it should be. Imagine if you were blowing up a balloon and the pressure inside was too high; that's similar to what's happening here.
The P2D24 code indicates that the voltage signal from the turbocharger interstage pressure sensor is higher than the expected range set by the vehicle's manufacturer.
The turbocharger interstage pressure sensor monitors the pressure between stages of the turbocharger. If the sensor's output voltage is higher than the manufacturer's specified limit, the engine control module (ECM) will trigger the P2D24 code. This could be due to a faulty sensor, wiring issues, or an actual increase in pressure.
• Check Engine Light illumination
• Reduced engine performance
• Possible engine hesitation or stalling
• Faulty turbocharger interstage pressure sensor
• Wiring issues such as short circuits or open circuits
• Actual high pressure in the turbocharger system
Turbocharger: A device that increases an engine's efficiency and power output by forcing extra air into the combustion chamber.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Use an OBD-II scanner to confirm the code.
• Inspect the turbocharger interstage pressure sensor and its wiring for damage.
• Measure the voltage output of the sensor and compare it to specifications.
• Replace the turbocharger interstage pressure sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Inspect the turbocharger system for actual high pressure issues.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regularly inspect and maintain turbocharger components.
• Ensure all sensors and wiring are in good condition.
• Perform routine vehicle diagnostics.
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Schedule a diagnostic check with a professional mechanic.
Check with your vehicle manufacturer to see if the sensor is covered under warranty.
This code has been reported in vehicles with turbocharger systems, particularly in models that have high-performance engines.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Ignoring this code could lead to reduced engine performance and increased emissions, which may not comply with emissions regulations.
• Engine running
• Turbocharger system active
The turbocharger interstage pressure sensor is typically located near the turbocharger assembly, often between the compressor and turbine stages.
Q: Can I drive with a P2D24 code?
A: It's not recommended to drive for extended periods with this code, as it may lead to reduced performance or further damage.
Q: How can I reset the P2D24 code?
A: After fixing the issue, you can reset the code using an OBD-II scanner.
