T INSTRUMENT CLUSTER 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- \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

PLASTIC BODY PARTS - REPAIRING URETHANE FASCIA - REPAIRABLE RANGE FOR URETHANE FASCIA Urethane fascia which has been damaged greater than shown below should be replaced with a new one. Though such fascia may be repaired, a quality problem will occur. In addition, this repair is not considered reasonable in terms of workload. Allowable Repairs 1. Fascia with a hole less than 30mm (1.18 in) in diameter. .-- 2. Fascia with a crack less than 150mm (5.90 in) in length. 3. Fascia with a crack less than 150mm (5.90 in) in length that is less than half of the width of the fascia. Gartner Banana

PLASTIC BODY PARTS REPAIRING POLYPROPYLENE FASCIA d REPAIRABLE RANGE FOR POLYPROPYLENE FASCIA The three examples of damage shown below are considered repairable. Although a bumper which has been damaged greater than this could also be repaired, it should be replaced with a new one. Any larger repair would detract from the looks and quality of the bumper. In addition, such repair is not considered reasonable in terms of workload. Allowable Repairs 1. A fascia with a hole less than 30mm (1.18 in) in diameter. 2. A fascia with a crack less than 150mm (5.90 in) in length. 3. A fascia with a crack less than 150mm (5.90 in) in length that is less than half of the width of the bumper. Gartner Banana
