Code P2160 Cadillac Description
The P2160 diagnostic trouble code (DTC) for Cadillac vehicles indicates a problem with the Vehicle Speed Sensor 2 Circuit, specifically a low voltage issue. The Vehicle Speed Sensor (VSS) is a crucial component in a vehicle's drivetrain system, responsible for monitoring the speed of the vehicle and sending this data to the engine control module (ECM) for various functions such as fuel injection timing, transmission shifting, and ABS operation.
Common Causes of P2160 Cadillac
- Faulty Vehicle Speed Sensor
- Damaged wiring or connectors in the VSS circuit
- Malfunctioning ECM
- Corrosion or contamination in the VSS connection
- Electrical issues such as a blown fuse or short circuit
Symptoms of P2160 Cadillac
- Erratic shifting in automatic transmissions
- Inaccurate speedometer readings
