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

BME014018842W02

  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
