What to do if your wheel speed sensor is not working?
Then they called in the services of a mobile electrician who tested the wiring and suggested it must be the control module. Luckily the garage didn’t replace the control module but they did remove it from the car and sent it for bench testing by a specialist (quite a significant job) but it came back “no fault found”.
Can a tire pressure sensor measure wheel speed?
Yes, a pressure sensor that doesn’t actually measure pressure… Indirect TPMS instead uses your car’s ABS system, tapping into the wheel-speed sensor to see if one tire is rotating faster than the others. Underinflated tires have smaller circumferences, which in turn means they have to rotate faster than a properly inflated tire.
Why does my tire pressure sensor keep failing?
If this still doesn’t do the trick and the light is constantly on, it could be a sign that you have a faulty tire pressure sensor. It’s not uncommon for the sensor itself to fail. Why Do Tire Pressure Sensors Fail?
What was the first wheel speed sensor fault?
The first was a Volkswagen Passat – The car came to us with a bit of history as another garage had looked at the car first and read a fault code which said “wheel speed sensor LHF incoherent”. They had tried fitting a wheel speed sensor but the fault was still present.
What happens when the wheel speed sensor does not work?
ABS does not work properly The anti-lock braking system is designed to apply smooth application of brake fluid to engage the brake calipers and pads to slow your car without locking up the tires. The wheel speed sensor is responsible for relaying the wheel speed to the ECU so that it can tell the ABS system how much pressure to safely apply.

What happens when the tire pressure sensor fails?
Sometimes it happens that the tire pressure control module and the tire pressure sensors lose communication with each other. If this happens, it can sometimes work to reprogram the sensors. To reprogram the sensors, you need a TPMS reset tool. 3. You changed wheels
