I wanted to know the estimate (labor + parts) to replace a knock sensor for a Subaru Legacy 2000 (2.5L) car.
How long does a job like this last?
The sensor cost is about $150 at auto parts stores and $103 at the dealer and about an hour labor in the book.
This is a pretty common issue with many Subarus. It is often an intermittent problem the sensor. Sensor will test OK in the shop and fail while driving.
the part cost are $75 autozone, you can reemplaze by yourself. Then you can reset the computer whit a friend scam.
