Gauge Inaccurate
Functionality and accuracy of coolant temperature gauge can be tested by using scan tool which provides direct control of gauge through selectable temperature points. If gauge pointer falls within designated area for all of its test points, then gauge is okay. Check gauge circuits. If gauge pointer does not fall within designated area for all its test points, replace gauge. See COOLANT TEMPERATURE GAUGE TEST POINTS .

|---|---|
| 0 | "C" |
| 2 | 1/2 |
