Temperature Gauge
WARNING: This page is about a different car, the 1996 Mazda Millenia and 1995 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
After changing checker resistance value, allow 2 minutes for needle to stabilize. Allowable limit of needle deflection is twice width of needle.
- Disconnect temperature gauge sending unit connector. Connect Red wire lead of Checker (49-0839-285) to temperature gauge sending unit connector terminal. Connect checker Black wire lead to ground.
- Turn ignition on. Set checker to specified resistance value. See TEMPERATURE GAUGE RESISTANCE . If temperature gauge needle rests at specified position for each resistance value setting, replace temperature gauge sending unit. If temperature gauge needle does not rest at specified position for each resistance value setting, check wiring between temperature gauge sending unit and instrument cluster. If wiring is okay, replace temperature gauge.
