Subaru EZ30 Cam hall sensor strange behavior
Posted: Sun Mar 12, 2023 8:07 pm
Hi all. Today while trying to get camshaft timing I found a very strange behavior of the camshaft sensor.
The fact is that at idle, the signal form from the sensor is formed from a falling form, and after an increase in engine speed, the signal form changes (is inverted) and changes to a signal rise. Can anyone come across this and how Rusefi will look for VVTi synchronization in this case?
This sensor is from Mitsubishi, its part number is J005T23781 Subaru part number is 22056AA101
Here is the waveform from the manual, the wiring diagram and pinout
