This is for a Haltech Platinum Sport 2000, using PnP harness on a JDM 2JZ-GTE in a JDM JZA80.
Preface: Early 2JZ-GTE engines mostly used Aisan position sensors, while later 2JZ-GTE engines exclusively used Denso position sensors. They are very similar, however not 100% identical. I have the different resistance measurements from the TSRM. Toyota only sells Denso replacements.
Problem: 2JZ-GTE was running pretty well, not too many problems, running well until it melted a piston (not really relevant to the issue at hand). When we pulled the engine out, we decided that we should make sure there are no other problems, so I ordered 6 new coils, new cam position sensors and a new crank position sensor. Now the ECU is seeing erratic RPM signal and I believe is losing track of the cam, causing the engine to die under load.
I have changed the crank position sensor back to the original one that had no problems and it hasn't changed anything at all, so I feel the problem must lie with the Denso cam position sensor, however I do not have the old Aisan one lying around to swap out and test.
Ideally I would really like to scope the sensor outputs to see what the sensor is ACTUALLY doing, but I don't have a scope at my immediate disposal.
What you can do to help: Anyone ever scoped a Denso JZ cam position sensor or crank position sensor? Have any results? Voltages at various RPM appreciated.
Not sure if anyone will have this information, but if you do, I'd love to see it!
