METER AND GAUGES — Thermal Transmitter Check / Oil Pressure Switch / Speedometer Cable Removal and Installation / Speed Sensor Signal Check
EL-91prose procedureUnverifiedOil pressure switch condition table is slightly garbled in source — 'Engine start' should have resistance ∞ (switch open under pressure) and 'Engine stop' should be ~0 (switch closed at low/no pressure). Captured as best-read; ohm-symbol marks are partially illegible.
Thermal Transmitter Check
NOTE
Check the resistance between the terminals of the thermal transmitter and body ground with the transmitter in situation.
• For a more accurate test, remove thermal transmitter and immerse in a vessel of water.
• Heat water, and test transmitter resistance at suitable temperatures to determine if transmitter resistance is changing correctly in accordance with temperature variation.

CAUTION
• Apply sealant to screw threads when refitting.
• Maximum installation torque — 14.51 N·m (1.48 kg·f.m).
Oil Pressure Switch
NOTE
Check the continuity between the terminals of oil pressure switch and body ground.
Engine start
Oil pressure kPa (bar, kg/cm², psi)More than 4.9 - 24.5 (0.049 - 0.245, 0.7 - 3.6)
Resistance value∞
Engine stop
Oil pressure kPa (bar, kg/cm², psi)Less than 4.9 - 24.5 (0.049 - 0.245, 0.05 - 0.25, 0.7 - 3.6)
Resistance value~0
CAUTION
• Apply sealant to screw threads when refitting.
• Maximum installation torque — 12.26 - 17.16 N·m (125 - 175 kg.cm).
Speedometer Cable Removal and Installation
NOTE
After disconnecting speedometer cable end from transaxle, push speedometer cable so that combination meter is pushed into passenger compartment. Disconnect speedometer cable end from combination meter as shown in the figure at left.
Speed Sensor Signal Check
NOTE
• A speed sensor is built into the speedometer.
- 1Turn speedometer slowly using a small screwdriver.
UEL077 - 2Check continuity of speed sensor circuit.
- Continuity exists two times for each turn ... O.K.
