Surely not.

Had multiple misfire CELs in February 2006 at 56400 miles. New Neutral Position Switch cured that one.

Now at 78000 miles, getting similar symptoms . Misfire on cylinders 1, 3 and 4 all at the same time, as if I wouldn't notice slightly rough running

Can the NPS last as lttle as 20k miles?

 

yes the end wears down, easy fix is available though that doesn't require replacing the switch.

 

Does it involve a pair of wirecutters?

As long as it doesn't involve buying a new car would you care to share with me? PM accepted.

 

looks like Zen's pulling your leg.

 

Sorry when it comes to technical matters i don't pull anyone's leg.

The problem can usually be fixed by changing a part that costs pennies. But it will cost you a few quid to find out, significantly less than the cost of a new switch however.

My car had this problem. It was causing my car to DET, when the switch was vibrating on/off around 5K revs. Not sure if the ECU would report that as a misfire?

Poor design if a simple switch like that can cause an engine to DET.

Looks like Subaru built the switch tip out of plastic, to earn dealers a few quid later down the line

What's this Neutral Position switch do?

 

I was told that it tells the ECU the gearbox is in neutral. This allows it to NOT activate the AVCS if IN neutral....

P.S. Don't know why.... except you don't need power in neutral maybe ?

 

Yes, the AVCS is switched off when the car's in neutral. So if your driving hard hard and the AVCS switches off unexpectedly, that must be what caused my DET.

You can put a thinner washer between the gearbox and the switch to cure it for a while longer.
