Located
on or inside your vehicle's transmission
, the turbine speed sensor measures the RPM of the turbine shaft. Once the PCM or TCM detects an irregularity in the turbine speed input, it will trigger the illumination of the Check Engine Light.
What does a turbine speed sensor do?
A turbine speed sensor, also termed an input speed sensor, is
used for measuring the performance of the turbine by evaluating transmission performance and other components of the turbine
. It also detects the rotation speed of the turbine, which shows the input revolution of the transaxle.
What are the symptoms of a bad turbine 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 turbine speed sensor?
To replace the speed sensor, you are going to pay, on average,
between $330 and $380
. The labor should only cost you between $80 and $100, while parts will run you about $265.
Is the speed sensor located?
Identification. The vehicle speed sensor, or VSS, is located
near the transmission's output shaft
. The specific placement of the sensor allows the sensor to detect, and report, to the engine's computer through attachment cabling, the rotation and speed of the shaft.
Can you drive with a broken speed sensor?
That is why in general,
it is unsafe to drive a vehicle with a broken wheel speed sensor
. If the wheel speed sensor becomes damaged or wears out, initially you probably won't notice much difference in the way your car performs if your ABS light comes on unless you are driving on slippery pavement.
Can I drive my car with a faulty 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.
What makes a speed sensor go bad?
As soon as the wheel turns, the cover is knocked off by the tone wheel teeth. It is common for dirt to accumulate on the sensor which inhibits its ability to generate a signal. … Although sensors can go bad, the most common problem is
faulty wiring or corroded electrical connections
.
How long does it take to replace a transmission speed sensor?
Most experienced technicians can replace the transmission speed sensor within
2-3 hours
. Depending on the severity of the damage it can take a bit longer.
Can 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.
How do I know if my wheel speed sensor is bad?
- ABS Light is illuminated on the dashboard. …
- ABS does not work properly. …
- Traction Control Light is active.
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.
Which speed sensor controls the speedometer?
The output speed sensor
measures how fast a vehicle moves and sends that information to other vehicle systems. The transmission control unit uses the speed to determine when to change gears, adjust the torque converter and display the vehicle's speed in the speedometer.
What can make a speedometer stop working?
The most common causes of a speedometer that stopped working include are a
faulty speed sensor
, a broken gear on the speedometer, damaged wiring, or a faulty engine control unit.
Will a bad speed sensor stop a car from shifting?
Without a valid speed signal from these sensors, the
PCM will not be able to correctly control the shifting of gears
within the transmission. … It's also common that a problem with these sensors can impact the shift timing, extending the interval between transmission shifts.
