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

id0140f1806200

  Note

  • Perform the following test only when directed.

## Resistance Inspection

1. Remove the IAT sensor No.2. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)])

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

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

  • If not as specified, replace the IAT sensor No.2.
  • If IAT sensor N0.2 is okay, perform the "Circuit Open/Short Inspection".

Specification

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

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)])

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

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

### Open circuit

  • IAT sensor No.2 terminal A and PCM terminal 79
  • IAT sensor No.2 terminal B and PCM terminal 74

### Short circuit

  • IAT sensor No.2 terminal A and power supply
  • IAT sensor No.2 terminal A and body ground
  • IAT sensor No.2 terminal B and power supply
