Is the inspection result normal? YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK INTAKE AIR TEMPERATURE SENSOR 2 SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between turbocharger boost sensor harness connector and ECM harness connector.
4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace error-detected parts.
3.CHECK INTAKE AIR TEMPERATURE SENSOR 2
Check intake air temperature sensor 2. Refer to EC-187, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> Replace turbocharger boost sensor (with intake air temperature sensor 2). Refer to EM-28, "Exploded View".
4.CHECK INTAKE AIR TEMPERATURE SENSOR 2 POWER SUPPLY CIRCUIT-II
Check the voltage between turbocharger boost sensor harness connector terminal and ground.
Is the inspection result normal? YES >> GO TO 5.
NO >> GO TO 7.
5.CHECK INTAKE AIR TEMPERATURE SENSOR 2 GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between turbocharger boost sensor harness connector and ECM harness connector.
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK ECM GROUND CIRCUIT
Check the continuity between ECM harness connector and ground.
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> Repair or replace error-detected parts.
7.CHECK SENSOR POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connectors and each sensor harness connectors 3. Check harness connector for short to power and short to ground, between the following terminals.
*1: CVT models
*2: RHD with M/T models
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
Component Inspection
1.CHECK INTAKE AIR TEMPERATURE SENSOR 2
1. Turn ignition switch OFF.
2. Disconnect turbocharger boost sensor harness connector.
3. Check resistance between turbocharger boost sensor terminals as follows.
Is the inspection result normal? YES >> INSPECTION END NO >> Replace turbocharger boost sensor (with intake air temperature sensor 2). Refer to EM-28, "Exploded View".
