    Description

    Banzai Racing TPS Tester
    Tester allows for easy adjustments of the Throttle Position Sensor on '84 - '91 RX-7s
    The Throttle Position Sensor (TPS) is part of the Fuel and Emission Control System. It has two major functions:
    To notify the ECU of the position of the throttle body. This allows the ECU to make adjustments to the air/fuel mix at different throttle positions.
    To cut the fuel off when you snap the throttle shut from being wide-open; this prevents backfiring.
    Most common signs of a TPS that needs adjustment is a rough idle or a hesitation problem during acceleration. Bad backfiring could also be caused by the TPS, but this can also be due to installation of an aftermarket free-flowing exhaust.
