This is a temperature to resistance chart for GM coolant and air temperature sensors.
1. Measure the resistance of a GM coolant or air temperature sensor and compare with chart.
2. Measured resistance should be at the resistance value on the chart based on the temperature of the sensor, plus or minus 50 ohms.
| Temperature - Degrees Fahrenheit | Resistance - Ohms |
| 210 | 185 |
| 160 | 450 |
| 100 | 1,600 |
| 70 | 3,400 |
| 40 | 7,500 |
| 20 | 13,500 |
