쐌 Before performing the following procedure, confirm that
battery voltage is more than 11V at idle.
With CONSULT-II
1) Install vacuum gauge between EGRC-BPT valve and EGR
valve as shown in the illustration.
2) Start engine and warm it up to normal operating temperature.
3) Stop engine and wait at least 5 seconds.

“EGR SYSTEM” in “DTC WORK SUPPORT” mode with CON-
SULT-II.
5) Start engine and let it idle.
6) Touch “START”.
7) Check the output voltage of “THRTL POS SEN” (at closed
throttle position) and note it.

THRTL POS SEN (X-(X+0.88) V
X = Voltage value measured at step 7
NOTE:
쐌 The bar chart on CONSULT-II screen indicates the status
of this test. However, the test may be finished before the
bar chart becomes full scale.
쐌 If the bar chart indication does not continue to progress,
