c. Connect the pocket tester (Ω × 1 k) to the
sub-throttle position sensor as shown.
• Tester positive lead →
Green/yellow "3"
• Tester negative lead →
Black/blue "2"
d. While slowly turning the sub-throttle posi-
tion sensor shaft, check that the sub-throt-
tle position sensor resistance is within the
specified range.
The resistance does not change or it
changes abruptly → Replace the sub-throt-
tle position sensor.
TIP
Check mainly that the resistance changes
gradually when turning the sub-throttle position
sensor shaft, since the readings (from closed
to wide-open sub-throttle) may differ slightly
from those specified.
Sub-throttle
resistance
0–7 kΩ

3. Install:
• Sub-throttle position sensor
TIP
When installing the throttle position sensor,
adjust its angle properly. Refer to "CHECKING
THE SUB-THROTTLE POSITION SENSOR"
on page 8-115.

a. Remove the air induction system solenoid
coupler from the air induction system sole-
noid.
b. Connect the pocket tester (Ω × 1) to the air
induction system solenoid terminal as
shown.

CHECKING THE ATMOSPHERIC PRES-
SURE SENSOR
1. Check:
• Atmospheric pressure sensor output volt-
age
Out of specification → Replace.
Atmospheric pressure sensor
output voltage
3.594–3.684 V at 101.32 kPa,
25 °C (77 °F)

a. Connect the test harness S-pressure sen-
sor 5S7 (3P) "1" to the atmospheric pres-
sure sensor and wire harness as shown.
