INSTRUMENTATION 5.3 Testing the Fuel Gauge 1 Remove the dash panel to access the fuel gauge. (fig. C2462) 2 With the ignition switch off, connect an ohmmeter between the “S” terminal and the “I” terminal. (fig. C307) 3 An ohmmeter reading of 150 to 250 ohms is normal. A higher or lower reading means the gauge is faulty and needs to be replaced. C307 NOTE: If the fuel gauge test results were good and the gauge still fails to function do the following test: 1 With the ignition switch off, connect an ohmmeter between the “S” terminal and the other end to ground. 2 An ohmmeter reading of 50 to 500 ohms is normal. A higher or lower reading means the wire going to the “S” terminal is faulty. NOTE:
If the test is good, check the fuel sending unit in the fuel tank for failure. 5 C308 5-9
