Code No. P0110 Intake air temperature sensor system
Range of Check
D Two seconds have passed since the ignition switch is turned ON or the
engine starting process is completed.
Set Conditions
D The sensor output voltage is 4.6 V or more for four seconds (equivalent to
- 45_C of intake air temperature)
or
D The sensor output voltage is 0.2 V or more for four seconds (equivalent to
125_C of intake air temperature)
MUT-II Data list
13 Intake air temperature sensor
OK: Roughly the same as ambi-
ent temperature.
NG
Check the intake air temperature
sensor itself.
(Refer to P.13A-90*.)
OK
Check the following connector:
B-12
OK
Measure at air flow sensor connector
B-12.
D Disconnect the connector and
measure at the harness side.
(1) Resistance between terminal 5
and earth
OK: 2 W or less
(2) Voltage between terminal 6 and
earth
(Ignition switch: ON)
OK: 4.8 - 5.2 V

Repair
(1) NG
Check the following connector:
C-40 <M/T>, C-176 <A/T>
Check the harness between the air
flow sensor and the engine-ECU
<M/T> or engine-A/T-ECU <A/T>.
Check the trouble symptoms.
(2) NG
Measure at engine-ECU connector
C-40 <M/T> or engine-A/T-ECU
connector C-176 <A/T>.
D Measure the voltage at the
engine-ECU terminal <M/T> or
engine-A/T-ECU terminal <A/T>.
D Disconnect connector B-12.
D Ignition switch: ON
D Voltage between terminal 62
<M/T>, 64 <A/T> and earth
OK: 4.8 - 5.2 V
Check the following connector:
C-40 <M/T>, C-176 <A/T>
Check the harness between the air
flow sensor and the engine-ECU
<M/T> or engine-A/T-ECU <A/T>.
Check the trouble symptoms.
Troubleshooting
Probable cause
D Malfunction of intake air temperature sensor
D Open or short circuit in intake air temperature
sensor or loose connector contact
D Malfunction of engine-ECU <M/T>
D Malfunction of engine-A/T-ECU <A/T>
