Default Check Engine Knock Senors Changed?

Hello Everyone,

I received a code that both my knock sensors are being rejected. I need my car to pass smog next week. I had my knock sensors changed 3 times in the past month and the wiring harness. What else could be the problem that would make these code keep popping up?

It's highly unusual for both knock sensors to fail simultaneously, although this could indicate a timing problem, and not necessarily knock sensor problem.

When the original problem started, did you get only 1 knock sensr code, and decided to change both of them at the sme time, or did literally both knock sensor codes appear together the first time?

Also, are you using after market knock sensors, or original Toyota/Lexus knock sensors?

What were the original knock Senors on the car when the problem first started. Original or aftermarket?

Phil
