6. Intake manifold air temperarure sensor (see Table 1-8) Table 1-8 7. Coolant temperature sensor (see Table 1-9) Table 1-9 41 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 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? Yes Next step No As per S/N 4 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) Yes Replace ECU No Replace sensor 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. Yes Repair or replace harness No Replace ECU 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 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? Yes Next step No As per S/N 4 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) Yes Replace ECU No Replace sensor 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. Yes Repair or replace harness No ECU Replace ECU
