I have an 2006 honda accord v6 couple model. It has 165k miles and lately I’ve noticed I’m getting terrible gas mileage. The car passed a smog check in southern California.
I’m considering on changing the 02 sensors. Does any knowledge if it’s okay or if there are any issues with using non dealer 02 sensors like Bosch? Is there a particular sensor that I need to change? This vehicle has 3 sensor and I’m not sure if I need to change all 3 or if I can just one in particular.
I also had the timing belt changed but the car starts and runs fine so I didn’t think it’s something to do with the timing.
Anyone the exact specs of when to change 02 sensor?
