This summary uses the existing diagnostic information shown in full below.
Your car's computer is having trouble with a part that tells it how fast the car is going.
The vehicle's control module is not properly processing the Vehicle Speed Sensor (VSS) output signal.
The P0608 code indicates that the Powertrain Control Module (PCM) has detected a malfunction in the Vehicle Speed Sensor (VSS) output circuit. This could be due to a failure in the sensor itself, wiring issues, or a problem with the PCM.
• Erratic speedometer readings
• Transmission shifting problems
• Check Engine Light illuminated
• Faulty Vehicle Speed Sensor (VSS)
• Damaged or corroded wiring or connectors
• Faulty Powertrain Control Module (PCM)
PCM: Powertrain Control Module
VSS: Vehicle Speed Sensor
• Use an OBD-II scanner to confirm the P0608 code.
• Inspect the VSS and its wiring for damage or corrosion.
• Test the VSS output signal with a multimeter.
• Replace the faulty Vehicle Speed Sensor (VSS).
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the Powertrain Control Module (PCM) if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regularly inspect and maintain vehicle wiring.
• Ensure connectors are clean and free from corrosion.
• Perform routine diagnostic checks with an OBD-II scanner.
Sensor Issue
• Avoid driving at high speeds until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
Check with your vehicle manufacturer for warranty coverage on the PCM or VSS.
The P0608 code has been associated with various models experiencing VSS issues, particularly in older vehicles.
Moderate – It is advisable to address this issue soon to prevent further drivability problems.
Ignoring this code can lead to unsafe driving conditions due to incorrect speed readings.
• Vehicle must be in motion.
• Engine at normal operating temperature.
The Vehicle Speed Sensor is typically located on the transmission or transaxle.
Q: Can I drive my car with a P0608 code?
A: It's not recommended, as it can cause inaccurate speed readings and affect vehicle performance.
Q: How do I reset the P0608 code?
A: After repairs, use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes.
