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 tells it how fast the car is going. It's like when your bike's speedometer isn't working right.
The vehicle's control module has detected an error with the speed sensor that is critical for monitoring safety functions.
The P325C code indicates that the control module responsible for monitoring safety-related functions has detected an error with the speed sensor input. This could affect systems that rely on accurate speed readings, such as ABS or traction control.
• Check Engine Light illuminated
• Erratic speedometer readings
• Inoperative ABS or traction control
• Faulty speed sensor
• Damaged wiring or connectors
• Malfunctioning control module
OBD-II: On-Board Diagnostics, a system for vehicle self-diagnosis and reporting.
ABS: Anti-lock Braking System, prevents wheels from locking up during braking.
• Use an OBD-II scanner to confirm the code.
• Inspect the speed sensor and related wiring for damage.
• Test the speed sensor for proper operation.
• Replace the faulty speed sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Regularly inspect and maintain vehicle sensors.
• Avoid harsh driving conditions that can damage sensors.
• Keep the vehicle's electrical system in good condition.
Sensor Issue
• Have the vehicle inspected by a professional.
• Avoid driving at high speeds until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on sensors and control modules.
This code has been associated with issues in vehicles with electronic stability control systems.
Moderate – Addressing this issue promptly can prevent further complications.
Driving with a malfunctioning speed sensor can affect safety systems and may be illegal in some regions.
• Vehicle at operating temperature
• On a flat surface
The speed sensor is typically located on the transmission or wheel hub assembly.
Q: Can I drive with a P325C code?
A: It's not recommended as it can affect safety systems like ABS.
Q: How do I reset the P325C code?
A: Fix the underlying issue and use an OBD-II scanner to clear the code.
