Check engine light - knock sensor - now gone??


Recommended Posts

Gasoline is reformulated all the time, espescially before winter. Iv'e seen this code thrown by a random tank of gas. Seems like once the ECU *relearns* for the new formulation it may stay gone.

 

Of course it may be that the sensor is bad. It's super easy to replace.

True, true, buckaroo. One plug dangling off a ground post. Mega-simple.

I replaced this on my 95 Legacy a couple months ago and it was super easy. I bought my sensor from O'Reiley's and it was $30 cheaper than either Autozone or Advance, if you r interested in non-factory replacement.

The part for mine was something like $95 at Autozone. I snagged one at our salvage yard (where they pull it for you) for $37. They even guaranteed it.

 

Come to think of it, I have an extra lying around somewhere that had the wrong plug shape on the end. If you end up needing the sensor, let me know. If the plug fits yours, I'll hook you up for way cheaper then the 'zone or NAPA!
