Canuck Tech :

This typically refers to the sensor itself within the throttle body assembly. If the connections are clean, did the mechanic check for proper pin tension at the connector? If the connection is loose, this code may set. Also, I have seen it where the throttle body needs to be replaced, because the sensor is not often available separate from the throttle body assembly
