Locate the transmission speed sensors, they'll be near the front and rear of the transmission housing .
What are the symptoms of a bad transmission speed sensor?
- Cruise Control Fails. The main function of the speed sensors is to monitor the output and input shaft speed. ...
- Improper Or Harsh Shifting. ...
- The Check Engine Light Indicates.
Is there a speed sensor on the transmission?
The transmission speed sensor is a small device that's located at the back or the front of the transmission . The transmission speed sensor consists of two sensors known as the input shaft speed sensor and the output shaft speed sensor.
Which speed sensor controls the transmission?
Typically, two sensors communicate the transmission data to the vehicle's powertrain control module. The first sensor, referred to as the input sensor , monitors the speed of the transmission's input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
How long does it take to replace a transmission speed sensor?
How long does it take to replace a transmission sensor? It can take a bit longer depending on the level of damage. Some professional technicians complete the entire replacement task in two or three hours .
What makes a transmission speed sensor go bad?
Over time, the transmission speed sensor can go bad due to wiring issues or just outright failing due to it constantly being used every time you are driving your vehicle. If the sensor is magnetic, it can go bad from iron sticking to the tip of the sensor, which will cause an inaccurate reading.
How much does it cost to replace a transmission speed sensor?
VSS Replacement
The DIY cost for replacing a speed sensor is the cost of the sensor. 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 .
What does the speed sensor do for the transmission?
Transmission speed sensors are used to calculate the actual gear ratio of the transmission while in use . There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle's powertrain control module.
Can you drive with a bad speed sensor?
Can you drive with a bad speed sensor? In general, it is unsafe to drive a vehicle with a broken wheel speed sensor . The car's computer will not be able to determine the speed that your vehicle is traveling, so it might apply the brakes at a faster rate than necessary or increase the engine power.
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.
Can a faulty ABS sensor cause transmission problems?
Occasionally, these sensors can fail or become faulty working intermittently sending inaccurate signals to the ECU. In your case it may be possible that the transmission is receiving a faulty signal from the ABS system.
Can a sensor cause transmission problems?
The Vehicle Speed Sensor measures a vehicle's speed. If it malfunctions or fails to work, then the automatic transmission may not operate as it should . This sensor may also cause the automatic transmission to go into failsafe mode – giving the appearance that the issue is more severe than it really is.
Will a bad throttle position sensor cause transmission problems?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems .
Is it hard to replace a speed sensor?
The vehicle speed sensor is one of the easiest parts on your car to change yourself. ... If you notice that the speedometer does not work any longer, replace the vehicle speed sensor as it is the most likely cause.
Can a speed sensor be cleaned?
The various components of the speed sensors can gather dirt from the road and from the dust that is generated by constant sharp braking. Speed sensors need to be cleaned on a regular basis to avoid damaging the anti-lock braking system.
