This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble understanding how far the gas pedal is pressed because the sensor that measures it isn't working right.
The throttle valve potentiometer measures the position of the throttle valve. This code indicates a problem with the signal from the second throttle valve potentiometer, suggesting it is out of range or not performing as expected.
The P1592 code is triggered when the Engine Control Module (ECM) detects an issue with the throttle valve potentiometer 2 circuit. This potentiometer is responsible for providing voltage signals that represent the position of the throttle valve. If the signals are inconsistent or outside the expected range, the ECM will set this code.
• Check Engine Light is on
• Poor engine performance
• Hesitation or stalling during acceleration
• Faulty throttle valve potentiometer
• Wiring issues such as open or short circuits
• Bad connections in the throttle body harness
Throttle Valve: A component that controls the amount of air entering the engine.
Potentiometer: A sensor that measures the position or angle of a component.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the throttle valve potentiometer for proper voltage and resistance.
• Replace the throttle valve potentiometer if faulty.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Screwdrivers

Moderate
• Volkswagen Passat
• Audi A4
• Skoda Octavia
• Regularly inspect and clean throttle body connections.
• Ensure wiring is free from damage and corrosion.
• Perform routine vehicle maintenance.
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
• Do not ignore the Check Engine Light.
Check with the vehicle manufacturer for warranty coverage on throttle components.
This code has been associated with throttle position sensor issues in vehicles with electronic throttle control systems since the late 1990s.
Moderate – While the vehicle may still be drivable, performance issues can worsen if not addressed.
Driving with a malfunctioning throttle system can lead to unexpected acceleration or stalling, posing a safety risk.
• Engine running
• Throttle pedal pressed
The throttle valve potentiometer is located on the throttle body, typically near the intake manifold.
Q: Can I drive with a P1592 code?
A: It's possible, but not recommended as it can lead to poor performance and potential safety risks.
Q: How do I reset the P1592 code?
A: After repairs, the code can be cleared with an OBD-II scanner. However, ensure the issue is resolved to prevent it from returning.
