What is the function of vehicle speed sensor?

A wheel speed sensor (WSS) or vehicle speed sensor (VSS) is a type of tachometer. It is a sender device used for reading the speed of a vehicle’s wheel rotation. It usually consists of a toothed ring and pickup.

What is code P0502 mean?

What does the P0502 code mean? The code means that the Engine Control Module (ECM) has identified a difference in speed reading between the vehicle speed sensor (VSS) and the wheel speed sensors.

What is code P2161?

Code P2161 is an indication that the ECM detects one of the two speed sensors needed to shift the transmission and transfer case properly is not working as needed and may cause transmission shifting problems.

What causes a P0503 code?

What the P0503 code means. The P0503 code indicates that the Engine Control Module (ECM) has detected an inconsistent signal voltage from the vehicle speed sensor.

What is code P0720?

The P0720 is an OBD code related to the workings and overall condition of the output speed sensor circuit. The Powertrain Control Module (PCM) in this particular circuit works by gathering a signal from the output speed sensor to assess and input the right shift strategy to the car’s transmission.

What are the symptoms of a failing speed sensor?

  • Transmission problems.
  • Erratic speedometer readings.
  • Inability to engage cruise control.
  • Lack of torque converter clutch application.
  • Check Engine Light is triggered.
  • An internal electrical fault in the speed sensor.
  • Damage on the sensor itself.
  • Poor vehicle maintenance.

How much does it cost to replace a speed sensor?

The average cost for vehicle speed sensor replacement is between $280 and $325. Labor costs are estimated between $117 and $148 while parts are priced between $163 and $177. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

Where is engine speed sensor located?

The sensor is located on the car’s transmission and this is why it is sometimes called the transmission speed sensor. It sends information to your speedometer and your engine’s computer to tell the transmission when to shift.

How do you fix a speed sensor?

What is the code for a bad speed sensor?

A P0500 code is a diagnostic trouble code (DTC) titled “Vehicle Speed Sensor (VSS) Malfunction.” This code is triggered when the vehicle’s Powertrain Control Module (PCM) or Engine Control Module (ECM) detects inaccurate speed readings or lack of a signal from the Vehicle Speed Sensor (VSS).

What does P0722 code mean?

P0722 code definition A P0722 code is stored when the PCM gets an incorrect or irrational input signal from the transmission’s output speed sensor. With an incorrect, intermittent, or inaccurate signal, the transmission has no accurate information about speed, and it cannot create an appropriate shifting strategy.

What is P0562 system voltage low?

A P0562 code relates to voltage supply drops that can occur in your vehicle. Specifically, the code is activated when the Power Control Module (PCM) detects an irregular drop in the voltage supply. For example, around 13.5 to 15 volts should be supplied to the battery when the engine is on.

Where is the speed sensor on a Mini Cooper?

The speed sensor is on the right side of the transmission. Look for a small plug-type component coming out from the side. The speed sensor is about 3 inches in length and has an electrical connector coming straight off of it.

Can a speed sensor be cleaned?

With the sensor free, take your rag and wipe the sensor until it’s clean. I prefer not to use any chemicals on the sensor to avoid potential problems. If, however, the sensor is really grungy, use a mild soapy solution and rinse well. The ABS sensors are precision instruments in a crude environment.

How do I fix error code P0720?

  1. Replacement of the output speed sensor.
  2. Replacement of the input speed sensor.
  3. Replacement of the wires or connectors.
  4. Drain and refill of the transmission fluid.
  5. Replacement of the PCM.

How do you test a transmission speed sensor?

Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor’s wire coupling. Using the multimeter’s voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.

Will a bad speed sensor throw a code?

Since the transmission speed sensors monitor the input and output shaft speed, it also plays a part in monitoring the cruise control. When the sensors fail to deliver accurate data to the onboard computer on your car, truck, or SUV, the powertrain control module (PCM) will send an error code to the vehicle’s ECU.

How long do speed sensors last?

There’s no hard-and-fast rule to help you predict how long your wheel speed sensor is going to last. Unlike a brake light switch or brake caliper that can last as long as your vehicle, you can expect your transmission speed sensor to last between 30,000 and 50,000 miles.

How many speed sensors does a car have?

Modern vehicles have four wheel speed sensors—one for each wheel of your car.

Is a speed sensor easy to replace?

Fortunately, it is easy to replace a wheel speed sensor and takes you about an hour at maximum. You can also remove the ABS wheel speed sensors separately keeping other parts integrated into the wheel bearing hub assembly.

How long does it take to change speed sensors?

Remove the old speed sensor. Replace it with a new one. The connector is in a plastic box hanging on the wheel well. 20 minutes.

Are speed sensors expensive?

Depending on the vehicle year, make and model, a speed sensor can cost as little as $7.92 or as much as $100. For most vehicles, the cost for a speed sensor is between $25 and $45. Follow these procedures for replacing a faulty vehicle speed sensor (VSS).

Will speed sensor affect transmission?

A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car’s powertrain module. The ISS sensor monitors the input shaft’s speed. If these sensors get misaligned, the operation of the transmission system will be affected.
