are you serious or do you consider us to be fools - you assume that the toyota nomeclature for crank sensor is universal? - the NE sensor in a toyota is a variable reluctance sensor - not every manufacturer uses that.
btw - how do you determine that the NE+ is for positioning? For understanding what I mean in plain saadi saadi terms.
Have you ever wondered why in some toyota applications the G- pin is shared between both the NE and G+ sensors? - ITS A reference signal - not a positioning signal. The ECU needs a set signal to reference against.
The positioning is detected by the cam phaser signal - In old toyota with group fire injectors and distributor like 4EFE etc. there was no G signal and the distributor just fired the ignitor on every crank signal phase as the 4 pole reluctor went past it. The injectors were paired so it did not matter what piston was where as long as the crank/cam belt was correct - it could not backfire.
Man - Till now I have seen some really blunt childish mistakes on your side.
1 - you assume the post cat o2 sensor has role in fuel trim
2 - you think that fuel trim can be more than 100%
3 - you think that the crank sensor can be phased out of time with no ill effects
4 - you think a 2 wire crank sensor has one wire for speed and one for phase.
5 - you think that lean mix is good for the cat.
What are you on about?
VCheng please - update the original first post of yours with these 5 findings.
