¥ 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 4 of MAIN PWB ASSY.
