Engine Coolant Temperature Gage Inaccurate or Inoperative Domestic
Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Was the Instrument Cluster System Check performed? | -- | Go to Step 2 | |
2 |
Are the engine coolant temperature and the indicated coolant temperature within the specified value of each other? | 17°C (30°F) | Go to Step 3 | Go to Step 4 |
3 | The temperature gauge functions properly. Inspect the engine cooling system for operating conditions, as needed. Does the temperature gauge operate properly? | -- | Go to Step 4 | |
4 |
Does the temperature gauge indicate the specified values after each adjustment of the tester? | 37.8°C (100°F) 126.7°C (260°F) | Go to Step 5 | Go to Step 6 |
5 | Replace the engine coolant temperature gauge sensor. Is the engine coolant temperature gauge operative? | -- | Go to Step 6 | |
6 | With the tester at 49.5 ohms, does the temperature gauge indicate a temperature significantly below the specified value? | 126.7°C (260°F) | Go to Step 8 | Go to Step 7 |
7 | Replace the instrument cluster. Refer to Instrument Cluster Replacement . Is the engine coolant temperature gauge operative? | -- | Go to Step 8 | |
8 |
Is continuity present? | -- | Go to Step 9 | Go to Step 10 |
9 | Repair the high resistance in CKT 35 (DK GRN) between the instrument cluster and the engine coolant temperature gauge sensor. Is the engine coolant temperature gauge operative? | -- | -- | |
10 | Replace the instrument cluster. Refer to Instrument Cluster Replacement . Is the engine coolant temperature gauge operative? | -- | -- |
