Temperature Gauge

  1. Check for blown fuse No. 23 (Integra) or No. 13 (Legend) in dash fuse block. Turn ignition off. Disconnect Yellow/Green wire from sending unit. Sending unit is threaded into cylinder head. Using a jumper wire, ground sending unit wire.
  2. Turn ignition on. Gauge needle should start moving toward "H" mark on gauge. Turn ignition off within 2 seconds or before gauge needle reaches "H" mark. Failure to turn ignition off before needle reaches "H" mark may result in damage to temperature gauge.
  3. If temperature gauge needle does not move, check for open circuit in Yellow and Yellow/Green wires. Replace temperature gauge if fuse and wiring are okay. If gauge is okay, check temperature sending unit.
