BOOST AIR TEMPERATURE SENSOR INSPECTION [L3 Turbo]

id0140b6802100

## Resistance Inspection

  Note

  • Perform the following inspection only when directed.

1. Disconnect MAP/boost air temperature sensor.

2. Measure the resistance between the MAP/boost air temperature sensor terminals A and B using a tester.

  • If not as specified, replace the MAP/boost air temperature sensor. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo].)
  • If the MAP/boost air temperature sensor is normal, but PID are out of specification, perform the "Circuit Open/Short Inspection".

Specification

Ambient temperature (°C {°F}) | Resistance (kilohm)
--- | ---
-20 {-4} | 14.04-17.33
20 {68} | 2.31-2.72
60 {140} | 0.572-0.655

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)

2. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)

### Open circuit

  • If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
  - MAP/boost air temperature sensor terminal A and PCM terminal 2H
  - MAP/boost air temperature sensor terminal B and PCM terminal 1S
  - MAP/boost air temperature sensor terminal C and PCM terminal 2K

### Short circuit

  • If there is continuity, there is a short circuit. Repair or replace the wiring harness.
  - MAP/boost air temperature sensor terminal A and power supply
  - MAP/boost air temperature sensor terminal B and power supply
  - MAP/boost air temperature sensor terminal B and body ground
  - MAP/boost air temperature sensor terminal C and body ground
