Fuel Systems Throttle Position Sensor (TPS) Overview CAUTION
The throttle position sensor (TPS) is set at the time of throttle body manufactureTPS adjustments should only be made if the TPS was loosened, repositioned, or replacedAny adjustments made to the TPS sensor or throttle synchronization screw will require performing the Digital Wrench Full Procedure (TPS Replacement) guided diagnosticThe throttle position sensor (TPS) is set at the factory based on throttle body idle air gap flow specificationTPS adjustments should only be performed when replacing the TPSNOTE: Follow these guidelines whenever working with the TPS: Use Digital Wrench when checking the TPS voltageDigital Wrench is the only tool that will readdisplay the actual TPS voltage the engine management system uses to determine throttle plate angle Disconnect the throttle cable from the throttle leverIf the throttle body idle air gap TPS voltage changes after removing the throttle cable from the throttle lever, the throttle cable is too tight and must be readjusted by turning the inline adjuster clockwise Verify the throttle cable is not pulling on the throttle plate camTurn the throttle cable inline adjuster clockwise to loosen the cableIf the cable continues to pull on the throttle plate cam, readjust the throttle cable threaded barrel on the throttle body All engine management sensorsswitches must be connected to obtain accurate TPS voltage readingsAfter removing the air box, reconnect the air temppressure sensor and lay the airbox inside the engine compartment Use fully charged 12V battery to power the engine management system
