if the sensor is not working anymore, the A/T computer module will interpret the absence of a reading that the engine is still cold -- consequently, it will prevent the transmission from going into overdrive.
btw, that part cost me P500.-- at goodgear. HTH and hope that this post did not arrive too late.
