Coolant Temperature sensor

Last update 07-04-2024
This is a +5V, 2-wire sensor. If your engine coolant temperature sensor has failed, you may notice one of several symptoms: your temperature gauge doesn’t move, your engine overheats without warning, your radiator fans don’t switch on, or they don’t switch off.
The coolant temperature sensor uses a 2-pin connector
| PIN | Function | Wire colors |
|---|---|---|
| 1 | Ground | Brown w/ Black stripe |
| 2 | +5V signal data | light gray w/ red stripe |
PIN from top left to bottom right
