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

For Cold Areas

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, -9.2- -11.2 inHg} is applied to port A of the fuel warmer.

• If as specified, inspect the following and carry out the "Circuit Open/Short Inspection".

• If not as specified, replace the fuel warmer.

Specification

Ambient temperature (°C {°F})	Resistance (ohms)
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 (harness-side) and GND

- Fuel warmer terminal B (harness-side) and power supply

Short circuit

• If there is continuity, the circuit is shorted. Repair or replace the harness.

- Fuel warmer terminal B (harness-side) and GND
