This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading the speed from one of the sensors that tells it how fast the car is going.
The P2160 code indicates that the vehicle's computer has detected a low voltage signal from the Vehicle Speed Sensor B, which is responsible for measuring the speed of the vehicle.
The Vehicle Speed Sensor B is part of the vehicle's speed monitoring system. It sends a signal to the Engine Control Module (ECM) to help determine the vehicle's speed. A 'Circuit Low' condition means the sensor is sending a signal that is below the expected voltage range, which could be due to a wiring issue, a faulty sensor, or a problem with the ECM itself.
• Inaccurate speedometer readings
• Transmission shifting issues
• Illuminated Check Engine Light
• Faulty Vehicle Speed Sensor B
• Wiring issues or poor connections in the sensor circuit
• Faulty Engine Control Module (ECM)
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the Vehicle Speed Sensor B for proper operation.
• Replace the Vehicle Speed Sensor B if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain vehicle sensors.
• Ensure wiring and connectors are clean and secure.
• Perform regular vehicle diagnostics.
Sensor Issue
• Do not ignore the Check Engine Light.
• Get the vehicle diagnosed by a professional if unsure.
• Avoid driving at high speeds until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on sensors and related components.
The P2160 code has been reported in various models over the years, often linked to sensor or wiring issues.
Moderate – While the vehicle may still be drivable, it can lead to inaccurate speed readings and affect transmission performance.
Driving with a malfunctioning speed sensor can lead to safety issues and may violate traffic laws.
• Vehicle at operating temperature
• Vehicle in motion to test speed sensor
The Vehicle Speed Sensor B is typically located on the transmission or differential.
Q: What happens if I ignore the P2160 code?
A: Ignoring the code can lead to inaccurate speed readings and potential transmission issues.
Q: Can I drive my car with a P2160 code?
A: While you may be able to drive, it is not recommended as it can affect vehicle performance and safety.
