• Calculate the voltage difference between TP sensor output
voltage at idle and TP sensor output voltage with the STV full
opened.
Example: TP sensor output voltage with the STV fully open
Minus TP sensor output voltage at idle is 0.08 V
STV fully open
Idle
! TP sensor output voltage variation: 0.064 – 0.096 V
• If the voltage variation is out of specification, turn in or out the
fast idle adjust screw 2 to adjust the voltage to specification.
#
The fast idle screw is factory-adjusted at the time of
delivery and therefore avoid removing or turning it
unless otherwise necessary.
• Cool down the engine to ambient air temperature and start the
engine to check the fast idle rpm comes within the specified
rpm.
! Standard
Fast idle rpm: 1 500 – 2 100 rpm/Cold engine
Idle rpm : 1 100 ± 100
• If it is not at the specified rpm, the cause may possibly be
short-circuit in water temperature sensor or w ring harness or
STVA.
