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 en
gine 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
a
t 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 settin
g procedure to verify proper vehicle operation.
