Great, thanks for the image, it is the only one I have come across that has the actuator in the same spot as my car. most others use a camry image along the front right wheel fender. Bear with me as I feel we are making progress. Please read below.
This is a Bosch ABS system. Not Nippondenso.
All the following measuements were taken with sensor harness disconnected and off the feed wire to sensor.
Ok, I have checked the other rear wheel which has not been giving me an open sensor code. With the harness sensor disconnected and no running engine, and no key in ignition I get 290 millivolts. With engine running and harness still disconnected from sensor I get 4.8volts. With key in ignition and accesories on, engine off, I get the same 4.8 volts. This is the sensor that is not giving me an error code. Are you sure no voltage should be present with wheels not rotating? If so, why do I not get a code for this sensor as well as the other? Nor do I get an ABS ECU error code? wouldn't I get an error code for the abs control module if it were blown?
On the side giving me the open sensor error code I get 11.4 volts, not millivolts, with engine off and no key in ignition and sensor disconnected. With engine running I get 13.4volts and with acceroriies on, no engine running, I get 11.6volts.
