Throttle Position Sensor Calibration

Before driving your vehicle, you must calibrate your Throttle Position Sensor as it is installed on your vehicle. Use this screen to initiate the calibration process and review the results.

The leftmost number shows the smallest voltage recorded during the calibration process. It corresponds to the 0% throttle position.

The rightmost number shows the largest voltage recorded during the calibration process and corresponds to the 100% throttle position.

The two voltages represent the minimum and maximum positions of the throttle position sensor.

The middle number is the current voltage from the TPS, and should move between the other two numbers as the throttle is moved.

If the measured throttle position sensor voltage exceeds either the minimum or maximum voltage, a TPS low or TPS high fault will be recorded in the system.

Before COMPUSHIFT II is properly calibrated, you will see "0.00" as the left-hand and right-hand numbers on the screen. In this situation, the system records both TPS low and TPS high faults until calibration.

During the calibration process, the left and right numbers are updated as the TPS is moved, defining the range of motion for the sensor which will result in the 0% and 100% readings.

Button	Function
	Press the "Select" button to begin the calibration process.

During the calibration process, you will see "Calibrating" at the top of the screen.

Once properly calibrated, you will see a low value for the left-hand number on the screen and a higher value for the right-hand number (no longer zeros).
