• The resistance of SENSOR has ±5% common difference.
• Measure the resistance of SENSOR after leaving it over 3 minutes in measuring temperature.
This postponing is necessary because of perceiving speed.
• Measure the F-SENSOR, SUPER FROST SENSOR, R1, R2-SENSOR after disconnect CON5 of PWB ASSY, MAIN.
