u Allowance of sensor resistance is 3%.
u Measure resistance value of sensor after leaving it for more than 3 minutes (delay is required due to sensing speed).
u Always use a digital tester! Analog testers have too great a margin of error.
u Measure resistance after separating PWB (PCB) assembly, the CON6 on the main part since the upper compartment
sensor and the middle compartment sensor have no connector. Measure resistance at both ends of No.6, 7 of the CON5
for the RT-sensor. However, measure resistance at both ends of the sensor after separating barrier assembly between
the middle compartment and the lower compartment for the lower compartment sensor.
