CHASSIS ELECTRICAL – Combination Meters54-30
ENGINE COOLANT TEMPERATURE GAUGE UNIT
CHECK
1. Bleed the engine coolant.
2. Remove the engine coolant temperature gauge unit.
3. Immerse the unit in 70C water to measure the resistance.
Standard value: 104 ±13.5 Ω
4. After checking, apply the specified adhesive around the
thread of engine coolant temperature gauge unit. Then,
tighten the unit to the specified torque.
Specified sealant:
3M Adhesive Nut Locking No. 4171 or equivalent
5. Add engine coolant.

VEHICLE SPEED SENSOR CHECK
1. Connect a 3 – 10 kΩ resistance as shown in the illustration.
2. Turn the shaft of the vehicle speed sensor one turn and
check that voltage changes are caused when measured
between terminals 2 and 3 using a circuit tester. (1 turn
= 4 pulses)
