$660 to replace O2 sensor 2006 civic hybrid?

Remove the wheel and the brake caliper/bracket assembly. Remove the center bolt from the hub assembly and pull the hub assembly off. Install in reverse order making sure the hub nut is torqued properly

Crankshaft position sensor. It indicates your timing is off.
Have you recently done some work on your engine or more specifically the distributor?

have you pulled any plugs after running? See if you are running lean or rich. Could be o2 sensor

change o2 sensor

I know of no reason to not use a aftermarket battery....but, to be on the safe side, go to your local auto parts store and see if they have a listing for the battery on your car.

Good luck!

a standard car battery is a standard car battery. Just go to your local auto parts store and they will get you the compatible battery with your vehicle.
Thanks,

Sometimes can be prematurely dirty air filter, sets off the air flow sensor, which sets off the o2 sensor. So might try new air filter first and erase codes and then see, before you spend more bucks than you need; then if codes return, do the flow mix sensor.

I would reccomend taking this vehicle to the dealer it is a very precise machine not to mention the potential of serious injury from the high voltage used in this car .

remove the rearseat back and unscrew the small plate in the center. then remove the plastic guard and flick to the off postion. it looks like a house breaker. then put plastic guard back to prevent acciedental switching.
