≤ -40 °F |
Go to Step 2 |
Intermittent Issue (Refer to Intermittent Diagnostics) |
|
2 |
- Disconnect the trans Oil Temp sensor connector and the sub harness connector - With a DVOM check for continuity between the trans fluid temp signal pin 1 & cavity "L" |
|
Go to Step 3 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
