Note. This procedure applies to analog meters only (not digital).
1. The test procedure described in this paragraph applies to the coolant temperature indicator, fuel level indicator in the tank, and oil pressure indicator. The voltmeter installed on the dashboard cannot be checked by the following method.
2. If the indicator needle does not move from the zero position, first check the fuse is good If the fuse is good, find the sensor of the corresponding indicator and check it is good (the location of the fuel level sensor is described in chapter 4, the location of the coolant temperature sensor is described in chapter 3, and the location of the oil pressure sensor is described in chapter 2B). Disconnect the wiring connector from the sensor and connect the connector terminal to the vehicle ground with a wire. If there are multiple terminals in the connector, find the correct terminal according to the wiring diagram (see end of chapter 12).
3. Briefly turn on the ignition. If the indicator arrow moves to the maximum mark. this indicates the health of the indicator and wiring and indicates a possible malfunction of the sensor.
Note. At the end of the check, turn off the ignition immediately, as this check may cause the indicator to malfunction.
4. If the indicator needle remains stationary, this indicates a possible malfunction of the indicator or wiring. Remove the dashboard and check for contact between the sensor and indicator terminal. In addition, make sure that power is supplied to the dashboard and that the dashboard ground wire has good ground contact. Refer to the appropriate wiring diagram if necessary (see end of this chapter). If the wiring and the sensor are OK, then the indicator may be faulty.
