5-3. Sensor resistance characteristics table
u
The tolerance of the sensor resistance is ±3%.
u
Measure the resistance value of the 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 a higher margin of error.
u
For left and right sensor, measure both sensor ends of the connector after separating the connectors of CON2 and 3 of
PWB (PCB) assembly and main part. For the outside sensor, measure end of 2 and 5 of CON5.
