Gauge Cluster – Civic ’92-95

This gauge cluster post applies to all Honda Civic and Del Sol models between 1992-1995.

The Honda Civic gauge cluster contains a speedometer, tachometer (if equipped), fuel gauge, coolant temperature gauge, and warning light displays. Cross-coil type gauges, in which 2 intersecting coils are wound around a permanent magnet, are used. An electronic speedometer is used.

FUEL GAUGE TEST

FYI: In Step 3), turn ignition off before fuel gauge pointer reaches “F” mark. Failure to turn ignition off before pointer reaches “F” mark may damage fuel gauge.

1. Turn ignition switch to OFF position. Check fuse No. 15 (10-amp) in dash fuse box. Remove fuel gauge sending unit access cover in luggage compartment. Disconnect 3-pin connector from sending unit.
2. Connect voltmeter positive lead to Yellow/White wire and negative lead to Black/White wire. Turn ignition on. Voltage should be 5-8 volts. If voltage is incorrect, check for open circuit in Yellow, Yellow/White, Black and Black/White wires. Check for poor ground connection.
3. Turn ignition off. Install jumper wire between Yellow/White wire and Black/White wire. Turn ignition on. Ensure fuel gauge pointer starts to move toward “F” mark on gauge. If fuel gauge pointer does not move, replace fuel gauge. If fuel gauge is okay, check fuel gauge sending unit.

FUEL GAUGE SENDING UNIT TEST

1. Ensure ignition switch is in OFF position. Remove fuel gauge sending unit access cover in luggage compartment. Disconnect connector from fuel gauge sending unit.
2. Remove fuel gauge sending unit. Use an ohmmeter to measure resistance between fuel gauge sending unit terminals with sending unit float held at empty (down), half-full (middle) and full (up) positions and compare readings. If resistance values are incorrect, replace fuel gauge sending unit.

FUEL GAUGE SENDING UNIT RESISTANCE – FLOAT POSITION

• Empty 105-110 Ohms
• Half-Full 25.5-39.5 Ohms
• Full 2-5 Ohms

TEMPERATURE GAUGE TEST

FYI: In Step 1), turn ignition off before gauge pointer reaches “H” mark. Failure to turn ignition off before pointer reaches “H” mark may damage gauge.

1. Ensure ignition switch is in OFF position. Disconnect and ground Yellow/Green wire on coolant temperature gauge sender. Turn ignition switch to ON position. Ensure gauge pointer starts to move toward “H” mark.
2. If gauge pointer does not move, check fuse No. 15 (10-amp) in dash fuse box. Check Yellow or Yellow/Green wire for an open circuit. If fuse and wiring are okay, replace temperature gauge. If gauge is okay, test temperature gauge sending unit.

TEMPERATURE GAUGE SENDING UNIT TEST

1. Disconnect Yellow/Green wire from temperature gauge sending unit. Use an ohmmeter to measure resistance of temperature gauge sending unit with engine cold. Start engine and allow coolant temperature to rise.
2. Measure temperature gauge sending unit resistance as coolant temperature rises. If resistance values differ from specifications, replace temperature gauge sending unit.

TEMPERATURE GAUGE SENDING UNIT RESISTANCE

• Honda Civic
  • 133°F (56°C) 142 Ohms
  • 185-212°F (85-100°C) 49-32 Ohms
• Honda Civic Del Sol
  • 133°F (56°C) 137 Ohms
  • 185-212°F (85-100°C) 46-30.4 Ohms

OIL PRESSURE SWITCH TEST

Disconnect Yellow/Red wire from oil pressure switch. Use an ohmmeter to check continuity of oil pressure switch. With engine off, continuity should exist between oil pressure switch terminal and ground. With engine running, continuity should not exist. If switch fails to operate as described, check engine oil level and oil pump pressure. If oil level and oil pump pressure are okay, replace pressure switch.

HAZARD WARNING SWITCH TEST – CIVIC

Carefully pry hazard warning switch from dash. Disconnect hazard warning switch 10-pin connector. With hazard switch in specified position, use an ohmmeter to check continuity between switch terminals. See figure. If continuity is not as specified, replace hazard warning switch.

HAZARD WARNING SWITCH TEST – DEL SOL

Carefully pry hazard warning switch and rear window defogger switch from dash together. Disconnect switch connectors. With hazard switch in specified position, use an ohmmeter to check continuity between switch terminals. See figure. If continuity is not as specified, replace hazard warning switch.

SPEED SENSOR INPUT TEST

1. Check 10-amp fuse No. 24 in dash fuse box. Disconnect 3-pin connector from speed sensor, located on right side of engine.
2. Use an ohmmeter to check continuity between Black wire and ground. If continuity exists, go to next step. If continuity does not exist, check Black wire for an open circuit. Also check for poor ground.
3. Turn ignition switch to ON position. Use a voltmeter to check voltage between Yellow/Blue and ground. If battery voltage is present, go to next step. If battery voltage is not present, check Yellow/Blue wire for an open circuit.
4. With ignition on, check voltage between Yellow/White wire and ground. If voltage is about 5 volts, go to next step. If voltage is not as specified, check Yellow/White wire for an open circuit.
5. If continuity and voltage checks are okay, but speedometer/odometer/trip meter does not operate properly, replace speed sensor.

INSTRUMENT CLUSTER REMOVAL AND INSTALLATION

Honda Civic:

1. Carefully pry hazard warning switch from instrument panel. Remove 3 trim panel mounting screws. Carefully pull trim panel from dashboard. Disconnect 4-pin connector and remove trim panel.
2. Remove screws and partially pull out instrument panel. Disconnect wiring harness connectors from instrument panel. See figure. To install, reverse removal procedure.

Del Sol:

1. Carefully pry hazard warning and rear window defogger switches from instrument panel. Remove 2 panel visor mounting screws. Carefully pull panel visor from dashboard.
2. Remove screws and partially pull out instrument panel. Disconnect wiring harness connectors from instrument panel. See figure. To install, reverse removal procedure.
