Coolant and Air Charge Temp Ford Coolant and Air Charge Temperature This is a temperature to resistance chart for Ford coolant and air charge temperature sensors. 1. Measure the resistance of a Ford coolant temperature sensor or air charge 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.
