You just met the love-child of legal & accounting. Dumb fuck juice +litigation gives us clutch start. Bean counters refuse to let engineering install a neutral position sensor inside the gearbox.

That one sensor would allow us to have a neutral start AND remote start on manuals so we don't boil in summer. But nooo, that's too expensive, so we get 2 clutch sensors which probably cost the same.

Bottom clutch sensor is for crank enable. Top is for gear position. When the pedal is fully released, gauge cluster guesses your gear based on wheel speed & engine rpm.

 

There is a neutral position switch in the manual transmissions, at least in my 2021 VA. It's part of the cruise control system. The cruise control system won't engage when in neutral and will disengage if you power shift without using the clutch. The switch gear position is also for cruise control.

 

Nope, I have the same one & I went through the shop manual and parts diagram multiple times. There's no position switch inside gearbox other than reverse for the camera.

Cruise control disengages because it compares engine rpm to wheel speed and realizes something is off. Also if you powershift without clutch, you won't have a gearbox eventually.

I had to look up the term "powershift" and of course someone has an analysis on youtube.

Off topic, but interesting and now i have learned something new.

 

If you stall at a light (which, of course, none of us do), would you take the time to shift to neutral, start, then into first, or simply push the clutch in, start, and go?

 

I'm pretty sure the parts diagram and shop manual are confusing wrx & STi gearboxes. The parts diagram shows those sensors on the front end. I found some pictures of the wrx trans:

There are no electrics anywhere other than the one reverse sensor. The STi gearbox has more wiring so it's possible that it has neutral sensor.

Ideally it would be an either/or situation. Press clutch or put in neutral to start. Easy enough to do.

 

Stalled twice since i bought this one. Once at a light , once at a drive thru. Check neutral,start engine -first gear dump clutch and burnout to regain manhood.

 

I saw the same parts diagram. I haven't been under my car yet, so I can't confirm.

So double redundancy. Wonder if the clutch switches are regular No/Nc 12v digital inputs or low voltage low current inputs that will cause trouble if you mess with them.

 

Here is one of silver_scooby's pictures with the locations of the neutral and reverse switches shown (based on Subaru's parts diagram).

From the wiring diagrams, the clutch cruise control switch provides 12V to the ECU when closed, while the neutral switch provides a ground. The clutch start switch provides 12V to the starter relay when closed.

 

So i could pull the start enable switches connector and jumper the contacts to close the circuit. This will put it in a start enable state always (without having to depress the pedal all the way to the floor).

Is the neutral switch part of the starter circuit or strategy?

Also does the engine ECU disable the starter when the engine is running?

 

Interesting I'll have to look again. Last time I checked I saw the reverse switch in the position you've shown it. No neutral switch. Ideally a neutral switch should allow for remote start on manuals with the oem parts.

That location is also right at the back next to center diff, not sure how you could possible get a neutral position reading there.

 

Any remote start would still have to get around the clutch switch in the starter circuit.

 

This YouTube video might give you an idea of how the neutral switch gets its input. Look at around the 12:20 time stamp.

 

Do you have access to the wiring diagrams for a 2024 TR? Trying to learn how this integrates with the new eyesight system.
