Detailed Description

Standard Ignition TH339 is a throttle position sensor used to report throttle movement to the vehicle control system. On 1995-2002 Mazda Millenia applications, this sensor helps the engine computer interpret throttle opening for fuel delivery, idle control, and drivability functions.
