FUEL WARMER INSPECTION [MZR-CD (RF Turbo)]

id0114f1089300

## Cold District Specification

1. Remove the fuel warmer. (See FUEL FILTER COMPONENT DISASSEMBLY/ASSEMBLY [MZR-CD (RF Turbo)].)

2. Verify that the resistance between terminal A and the fuel warmer body is within the specification when vacuum of -31.3- -38.0 kPa {-235- -285 mmHg, -9.3- -11.2 inHg} is applied to port A of the fuel warmer.

  • If as specified, carry out the "Circuit Open/Short Inspection".
  • If not as specified, replace the fuel warmer.

Specification

Ambient temperature (°C {°F}) | Resistance (ohm)
--- | ---
20 {68} | 0.5-1.5

## 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

  • If there is no continuity, the circuit is open. Repair or replace the harness.
  - Fuel warmer terminal A and body ground
  - Fuel warmer terminal B and power supply

### Short circuit

  • If there is continuity, the circuit is shorted. Repair or replace the harness.
  - Fuel warmer terminal B and body ground
