“21” (P0110-H/L) IAT SENSOR CIRCUIT MALFUNCTION
NOTE:
IAT sensor is incorporated in the IAP sensor/TP sensor.
INSPECTION
Step 1 (When indicating 21:)
1) Turn the ignition switch OFF.
2) Remove the right leg shield. (
#
5-6)
3) Check the IAT sensor coupler
1
for loose or poor contacts.
If OK, then measure the IAT sensor voltage at the wire side
coupler.
4) Disconnect the IAT sensor coupler and turn the ignition switch
ON.
5) Measure the voltage between Dg wire
A
and ground.
6) Also, measure the voltage between Dg wire
A
and Br/B wire
B
.
