FUEL TEMPERATURE SENSOR INSPECTION [MZR-CD (RF Turbo)]

BME014018843W01

  Note

  • Perform the following test only when directed.

## Resistance Inspection

1. Disconnect the negative battery cable.

2. Remove the supply pump. (See SUPPLY PUMP REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

3. Measure the resistance between the fuel temperature sensor terminals using an ohmmeter.

  • If not as specified, repair the supply pump. (See SUPPLY PUMP INSPECTION [MZR-CD (RF Turbo)].)

Specification

Ambient temperature (°C {°F}) | Resistance (kilohm)
--- | ---
20 {68} | 2.0-3.0

## 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 harness.

### Open circuit

  • Signal circuit
  - Fuel temperature sensor terminal A and PCM terminal 35
  • GND circuit
  - Fuel temperature sensor terminal B and PCM terminal 91

### Short circuit

  • Signal circuit
  - Fuel temperature sensor terminal A and PCM terminal 35 to power circuit
  - Fuel temperature sensor terminal A and PCM terminal 35 to GND
