INTAKE AIR TEMPERATURE (IAT) SENSOR NO.2 INSPECTION [MZR-CD (RF Turbo)]

Note

• Perform the following test only when directed.

Resistance Inspection

1. Place the IAT sensor No.2 in water with a thermometer, and heat the water gradually.

2. Measure the resistance between the IAT sensor No.2 terminals using an ohmmeter.

• If not as specified, replace the IAT sensor No.2.

Specification

Water temperature (°C {°F})	Resistance (kilohm)
20 {68}	2.21-2.69
80 {176}	0.29-0.35

Circuit Open/Short Inspection

1. Inspect for open/short circuit in the following wiring harnesses.

• If there is open/short circuit, repair or replace wiring harnesses.

Open circuit

• Signal circuit

- IAT sensor No.2 terminal A and PCM terminal 8

• GND circuit

- IAT sensor No.2 terminal B and PCM terminal 91

Short circuit

• Signal circuit

- IAT sensor No.2 terminal A and PCM terminal 8 to power circuit

- IAT sensor No.2 terminal A and PCM terminal 8 to GND
