TPS Set Procedure Menu

The TPS Set Procedure Menu must be accessed to perform the following procedures:

• Idle Voltage Setting Adjustment

• Base and Idle Voltage Adjustments - TPS Replacement

• Throttle Body Synchronization-Full Adjustment Procedure

To access the TPS Set Procedure Menu, click on the Special Tests (Red Tool Box) button.

Select Menu Option 3 - TPS Set Procedure

The next screen will display the current idle voltage setting. The text will match the voltage specification required by the
vehicle.

If the voltage is within specification, the dialogue box will indicate the current TPS setting is within specifications, and
the CONTINUE button will be RED.

If the voltage is outside specification, the dialogue box will indicate the current TPS setting is outside specifications, and
the CONTINUE button will be GREEN.

If the technician clicks on the RED CONTINUE button on the TPS Setting screen, the following screen will be displayed.
This screen prompts the user to verify they want to make an adjustment to the TPS knowing the idle voltage setting is
within specification.

Clicking NO will end the procedure and return the user to the Special Tests Menu. Clicking YES will display the TPS
Initialization Procedure screen.

This is the TPS Initialization Procedure screen. A detailed description of each procedure is outlined below.

IDLE SETTING

Access the Idle Setting procedure to set the idle speed voltage. Digital Wrench will guide the technician through the
process for setting the TPS idle voltage. This procedure should only be performed if the TPS idle voltage setting is
incorrect, or when minor adjustments to the engine idle speed are desired.

Minor adjustments to the engine idle speed may be desired if the engine idle is too low or too high due to extreme external
environmental factors such as altitude. In addition to environmental factors, normal throttle body component wear and
tear may cause changes in idle speed over the life of the vehicle. The idle speed screw can be adjusted to compensate
for these changes.

IMPORTANT: Never set the TPS idle voltage below or above the specified voltage range. Setting the idle voltage
at the low end of the range will result in a lower idle speed. Setting the idle voltage at the upper end of the scale
will result in a higher idle speed.




Always check engine idle speed when the engine is at operating temperature and the idle speed has stabilized.

Engine idle speed with the engine at operating temperature is 1700 +/- 200 RPM.

NOTE: Test vehicle after performing the idle setting procedure to verify proper vehicle operation.

BASE AND IDLE SETTING

Access the Base and Idle Setting procedure when repairing a loose TPS sensor, or when replacing the sensor with a
new part.

NOTE: New throttle body service parts include the TPS sensor and are set at the time of manufacture. Do not
perform the Base and Idle Setting procedure.

Digital Wrench will guide the technician through the process of establishing the TPS baseline voltage and TPS idle
voltage settings.

NOTE: Test vehicle after performing repairing/replacing TPS sensor and after completing base and idle
setting procedure to verify proper vehicle operation.

FULL PROCEDURE (Synchronization)

Access the Full Procedure (Sync) procedure only when it is known the throttle body plate synchronization screw has been
tampered with and the throttle plates are out of synchronization.

Digital Wrench will guide the technician through the process of establishing the correct synchronization between the MAG
and PTO throttle plates, setting the TPS baseline voltage, and setting the TPS idle voltage.

IMPORTANT: If the technician cannot confirm the throttle plate synchronization is set correctly, throttle body
replacement is required.

NOTE: Test vehicle after performing the full procedure (synchronization) procedure to verify proper vehicle
operation.

CAUTION

The throttle position sensor (TPS) is set at the time of throttle body manufacture. TPS adjustments should only be

made if the TPS was loosened, repositioned, or replaced.

Any adjustments made to the idle air gap screw, TPS sensor, or throttle synchronization screw should only be

performed when directed to so by the Digital Wrench Diagnostic Software.

CAUTION

Severe engine damage may occur if the throttle plate synchronization is tampered with or set incorrectly. Read and

understand the instructions outlined in Digital Wrench when performing this procedure.
