6. Intake manifold air temperarure sensor (see Table 1-8)
Table 1-8
Diagnostic Trouble Code (DTC) Trouble Location or Type
P0112 Intake air temperature circuit input low
P0113 Intake air temperature circuit input high
S/N Operation Test Results Actions
1 Ignition switch in position ON. Next step
Yes Next step
2
Disconnect the intake manifold absolute
pressure/intake air temperature sensor from the
harness. Measure the voltage between pin (1) and pin
(2) with a multimeter. Is the voltage about 5V?
No As per S/N 4
Yes Replace ECU
3
Measure the resistance between pin (1) and pin (2)
with a multimeter. Does the resistance match with its
temperature? (refer to relevant part of the manual)
No Replace sensor
Yes Repair or replace harness
4
Connect an adapter between the ECU and the
harness. Check for open or short circuit between pin
J1-21, J1-04, J1-27 of the ECU and the pin (1), (3), (2)
of the sensor with a multimeter.
No Replace ECU
7. Coolant temperature sensor
(see Table 1-9)
Table 1-9
Diagnostic Trouble Code (DTC) Trouble Location or Type
P0116 Engine coolant temperature circuit range/performance
P0117 Engine coolant temperature circuit input low
P0118 Engine coolant temperature circuit input high
P0119 Engine coolant temperature circuit breaks at interval
S/N Operation Test Results Actions
1 Ignition switch in position ON. Next step
Yes Next step
2
Disconnect the coolant temperature sensor from the
harness. Measure the voltage between pin (1) (+) and
pin (3) (-) with a multimeter. Is the voltage about 5V?
No As per S/N 4
Yes Replace ECU
3
Measure the resistance between pin (1) and pin (3)
with a multimeter. Does the resistance match with its
temperature? (refer to relevant part of the manual)
No Replace sensor
Yes Repair or replace harness
4
Connect an adapter between the ECU and the
harness. Check for open or short circuit between pin
J1-05, J1-43 of the ECU and the pin (1), (3) of the
sensor with a multimeter.
No ECU Replace ECU
