Plymouth Speed Sensor

What are Speed Sensors and where are they Located?

Your vehicle’s transmission speed sensor(s) are crucial components to all modern vehicles. These sensors are mounted on the transmission or transaxle. Your vehicle’s control unit (ECU, TCU, or PCM) uses information from these sensors in conjunction with other sensor information to precisely control functions such as automatic transmission shift points, engine ignition timing and air / fuel ratio, as well as other functions.

Output Vs. Input Speed Sensors

A vehicle speed sensor (VSS), also known as an output speed sensor (OSS), is what tells your vehicle’s control unit how fast the vehicle is going. Your vehicle’s speedometer and odometer rely on the information from this sensor. Some vehicles also have a transmission input speed sensor (ISS), also known as a turbine shaft speed sensor (TSS), which is used to tell the control unit the rotational speed of the input shaft or torque converter. By using information from both sensors, the control unit can make the necessary adjustments to allow the vehicle to run efficiently and shift smoothly.

Speed Sensor Failure

Symptoms of a failed or failing speed sensor can vary depending on the year and model of the vehicle, but the most common would be an inoperative speedometer, improper shifting, and / or check engine light. Common OBD-II Trouble Codes related to transmission speed sensors include:

P0500 - Vehicle Speed Sensor Malfunction
P0501 - Vehicle Speed Sensor Range / Performance
P0502 - Vehicle Speed Sensor “A” Low Input
P0503 - Vehicle Speed Sensor Circuit Intermittent
P0700 - Transmission Control System Malfunction
P0705 - Transmission Range Circuit Malfunction
P0715 - Input / Turbine Speed Sensor Circuit Malfunction
P0716 - Input / Turbine Speed Sensor Circuit Range / Performance
P0717 - Input / Turbine Speed Sensor Circuit No Signal
P0718 - Input / Turbine Speed Sensor Circuit Intermittent
P0720 - Output Speed Sensor Circuit Malfunction
P0721 - Output Speed Sensor Circuit Range / Performance
P0722 - Output Speed Sensor Circuit No Signal
P0723 - Output Speed Sensor Circuit Intermittent
