I would like to tap into the engine speed raw signal from the crank/engine speed sensor (with oscilloscope). Where is a good place to access the signal?
IIRC, the sensor (driver side bell housing) pig tail goes into a connector. Does anyone have a pin out of the connector?
At the ECU, what pin carries the signal?
pin 82 - G28 engine speed sensor (gr = grey)
(pin 86 - G163 camshaft position sensor 2)
(pin 87 - G40 camshaft position sensor 1)
pin 90 - G28 engine speed sensor (bl = blue)
With above 2 pins (if they are correct) assigned to engine speed sensor: which carries what signal? which should I tap with osci (assume osci ground to driver side engine bay ground)?
