I have 01 forester that gave me a code for a bad Knock Sensor. So I spent about $75 and replaced the so called Knock Sensor. I cleared the code and drove the car, and all of the sudden my check engine light comes on again. This time I am getting a P0402 reading which is the catalyst. Is there any option other than spending almost $400 to change the catalyst? thanks
