Which O2 sensor do i want?

[theSOB]

I see they are different for Dx, Lx, and Ex. is this because of the position of the sensor on the header or the ecu or what? i have an ebay header and the sensor is at the base of only 2 of the cylinder downpipes rather than at the base of where all 4 come together like my cast iron header for my f22a1 engine. would this cause a problem? also, if i switch to the f22a6 ecu should i get the Ex O2 sensor? thanks!

also: the Ex sensor is cheaper than the Dx and Lx

First, be sure you get a Denso or NGK/NTK o2 sensor. DO NOT GET BOSCH, or any cheapie brand.

The only difference should be the mounting location. The LX/DX had it mounted in one place, and the EX has it mounted in another. The wire length will vary. If your cheap header moved the sensor location from the F22A1 location to the F22A6 location, then get the F22A6 sensor. You do not need a different ECU.

thanks deev!

you say you found an EX o2 sensor for cheaper? where? there all more expensive from what i've found. I just spliced mine to make it work. But the sensor itself didnt look to good, so Im on the lookout for some good prices.

autozone has them at a cheaper price. not sure y

[93.4dr.22A1]

right on man, thanks! The one place I forgot to check.

[93.4dr.22A1]

that o2 sensor is not the correct one. it says its 13.9 inches long. Thats about how long of a wire I spliced in to make my A1 o2 sensor work.

weird. i wouldn't think autozone to be wrong

[93.4dr.22A1]

IDK, dont have an Ex to look at, but maybe the plug that comes off the wiring harness for the the o2 sensor is in a different place. Mine is underneath the spot where the top radiator hose mounts to the motor, I know theres a word for it, but having a brain fart atm.

NEVER trust Autozone to be right. They'll sell you a $60 sensor that won't work correctly in your car. Buy your sensor from Honda if you don't know exactly what you need to buy. HONDA won't be wrong. Autozone is most likely wrong than not. You don't need to know cars to work there...

DO NOT GET BOSCH

what's wrong with them? I bought one almost one year ago for...100$ - I don't think it was cheap! (Number 0 258 005 710)!! The price of NGK was about 150$

[deevergote]

NGK will run about $150. Bosch around here is often $65 or so.

Bosch sensors aren't wired correctly, and will give improper readings. They will foul quickly as well. There are ways to fix them, but you have to do some soldering.

The sensor wire for the ex is located behind the block, spliced in near the oil sensor and the tps cable

I bought a denso o2 sensor for my EX today that cost mean a little more than $53 including tax. I found the company on ebay buit they are local so i went and picked it up on my lunch today....its really a denso. Their ebay seller name is onlinewholesaleparts and i think if u add dot com you get their website(ill check when i get in my car). Only use Denso, ngk or ntk o2 sensors, some get lucky with bosch but dont risk it. Buying from this seller with get u a denso for cheaper than a bosch.
