Problem Job: ABS sensor remains lit after sensor replacement

Standard practice of clearing the code by re-setting the ECU does not always remedy the problem, says Cambiare

Problem Job: ABS sensor remains lit after sensor replacement
Cambiare investigates ABS sensor warning light issues.

When driving the vehicle, the driver may notice a loss of wheel traction and the ABS warning light will appear.

The symptoms suggest that the ABS sensor is at fault and the part is replaced.

However, Cambiare say the warning light may remain active because the ABS sensor won’t generate a reading until the vehicle is travelling between 2-5mph.

In a statement, Cambiare said: “To ensure the new sensor is registered, the wheel will need to be spun by hand.

“By spinning the wheel, the sensor generates a current which will be picked up by the ECU.

“This will ensure that the sensor is registered, removing the warning light from the dashboard.”
