8-3 RESISTANCE SPECIFICATION OF SENSOR
• The resistance of the SENSOR has a ±5% tolerance.
• Measure the resistance of the SENSOR after leaving it for over 3 minutes in the measuring temperature.
This delay is necessary due to sensor response speed.
• Measure the F-SENSOR, SUPER FROST SENSOR, R1, R2-SENSOR after disconnect CON5 of PWB ASSY, MAIN.
