My CEL came on for the first time two days ago, I pulled the code and got 0707 and 0304, Rear o2 sensor and knock sensor. Are these known to go out at the same time or is it just a fluke?

I'm already in the process of purchasing a knock sensor, my other question is, how long is it ok to drive without having them replaced? I'm taking a road trip to Austin later tonight and am a tad nervous about it.

Thanks

 

Have you tried to clean the sensors and re-set the ECU?

Just a thought.

 

Yes, I have tried reseting the ECU. I will go ahead and try to clean the sensors and see if that helps.

 

I meant: Clean sensors first, then re-set ECU.
