T INSTRUMENT CLUSTER INSTRUMENT CLUSTER STRUCTURAL VIEW 1. Speedometer 2. Tachometer 3. Water temperature gauge 4. Fuel gauge 5. Oil pressure gauge 6. Warning and indicator lights 7. Trip meter 8. Odometer DESCRIPTION Speedometer Two scales are shown on the speedometer face. The main scale for U.S. specification vehicles is MPH (0-140 MPH); the main scale for Canada specification vehicles is kmlh (0-220 kmlh). The odometer indication is the same as the main scale. Tachometer The tachometer has a RED STRIPED ZONE (6,500-7,000 rpm) that indicates momentary allowable engine speed. The engine should not be operated in the RED ZONE (7,000-8,000 rpm). Fuel Gauge 2 The fuel gauge continues to indicate the amount of fuel remaining in the fuel tank after the ignition switch has been turned OFF. Gartner Banana

T INSTRUMENT CLUSTER Symptom: Oil pressure gauge does not operate. 05UOTX-468 Preparation SST I 49 0839 285 For inspection of Checker, fuel gauges and thermometer Step 1 1. Disconnect the connector from the oil pressure sensor. 2. Connect the red lead of the SST to the A (YIR) terminal wire and the black lead to ground. 3. Turn the ignition switch ON. 4. Set the SST to the resistance values shown in the figure. To get an accurate reading, wait 2 minutes after setting each value. 5. Verify that the gauge indicates the correct values. The al- lowable indication error is twice the width of the needle. I Incorrect I GO to step 2 Gauge display Correct Step 2 1. Remove the instrument cluster. (Refer to page T-29.) 2. Apply battery positive voltage to terminal 2K and ground to terminal 2J. 3. Connect the red lead of the SST to terminal 26 and the black lead to ground. Action Replace oil pressure sensor 4. Set the SST to the resistance values shown in the figure. To get an accurate reading, wait 2 minutes after setting each value. 5. Verify that the gauge indicates the correct values. The al- lowable indication error is twice the width of the needle.

Verify that the gauge indicates the correct values. The al- \J lowable indication error is twice the width of the needle. 6. If not as specified, replace the oil pressure gauge. PRINTED CIRCUIT lnspection 1. Remove the instrument cluster. (Refer to page T-29.) 2. Check the printed circuit for damage or oxidization. 3. If necessary, replace the printed circuit. VEHICLE SPEED SENSOR lnspection 1. Remove the instrument cluster. 2. Connect an ohmmeter between terminals 2D and 2F. 3. Verify that the ohmmeter needle pulsates while rotating the speedometer cable shaft. ~ Pulsation: Ushaft rotation 4. If the correct number of pulsations fail to occur during each shaft rotation, replace the vehicle speed sensor. (Refer to page T-29.) WATER TEMPERATURE SENDER UNlT lnspection 1. Remove the sensor. 2. Place the sensor and a thermometer in water. 3. Heat the water gradually, and measure the resistance of the sensor with an ohmmeter. 4. If the resistance is not as specified, replace the sensor. Resistance: 190-260Q at 50°C (1 22°F) FUEL GAUGE SENDER UNlT (IN FUEL TANK) lnspection 1. Remove the fuel tank gauge sender unit. (Refer to section F.) 2. Disconnect the fuel gauge sender unit connector. 3. Check resistance between terminals A and B while slow- ly moving the unit arm from point F to point E. 4. If not correct, replace the fuel gauge sender unit. 2 Gartner Banana
