3. SENSOR RESISTANCE CHARACTERISTICS TABLE
• The tolerance of sensor resistance is ±5%.
• Be sure to measure the sensor resistance after keeping the sensor more than 3 minutes at a measuring temperature.
(It needs delay due to sensor speed.)
• Measure the resistances of SENSORs with a digital tester after disconnecting CON 3 of MAIN PCB ASSY.
