Similarly, it is asked, what happens when a speed sensor goes bad?
When there are symptoms of a bad transmission speed sensor, the powertrain control module cannot control the shifting of gears within the transmission properly. This may cause transmission revs higher before shifting gear or leading late transmission overdrive and inability to go into that top gear.
Secondly, what is the work of speed sensor? The output shaft speed sensor detects the speed of the drive wheels and sends this information back to the engine control unit. Together these two shafts allow the wheels to rotate at a speed that is manageable while the engine continues to run at a speed that makes it perform efficiently.
Beside this, what are the symptoms of a bad speed sensor?
Here are the symptoms of a bad or failing transmission speed sensor
- Harsh or improper 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.
- Cruise control does not work.
- Check Engine Light comes on.
Can I drive my car with a bad 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.
