Oxygen sensors

[Max]

Rear view of engine showing the UPPER two sensors. The one boxed is Bank 2, Sensor 1. Next to it on the left is Bank 1, Sensor 1. Now, directly below and after the cat convertor (but not pictured) are the 2nd set of sensors. Bank 1 & 2 number 2 sensors.



These next two pics are of the wire lead CLIPS that you have to disengage from the wiring harness. As you can see in the 2nd pic, it was easier to destroy the engagement part of the OLD sensor plug, than to try and remove it conventionally. The area is REAL tight to get to. I used a super small screw driver to break the bond. I went in from below the car to access it. On the clip pic...don't worry about those little SIDE retaining clips. They hold the end of the plug TOGETHER, but not to the mating harness plug half.




The must have tools...22mm sensor socket and flex head ratchet.



Disengaging the CLIPS was the hardest part. Hope this helps.

I still contend that not ALL of your sensors are faulty, BUT...Zuki recommends sensor replacement at 100,000 miles in support of your changing them out.

I'm still enjoying terrific engine performance and 25/26 MPG jaunts!

Here's a pic of my first and only bad sensor at 205,000 miles!

Thank you so much, I could not find better information anywhere on the web. This is perfect. I will get the codes read again just for good measure. I too found it hard to believe all were faulty.

Cool! And you're welcome. Glad to help.

Keep us posted.

I thought we were talking about a Verona?
The previous pics are excellent but for the GV/XL V6 engine not the straight inline 6 used on the Verona.

But to clarify the positions. Bank 1 is sensors are BEFORE the catalytic converter. Bank 2 is after the converters. So, Bank1 Sensor 1 is top sensor closest to the drive belts. B1S2 is closest to belts but downstream after the converter. Bank2 is of course the driver side sensors.

Again, this may be covered under warranty!

as follows. Once you retrieve them from the code scanner you can pinpoint the faulty sensor right down to the bank and sensor #.

Hmmm....Don. Have I confused the issue? Techfella said that he's running a 2.5! Is that not the V-6 H25 engine? If not, I appologize for inserting the info. Again, I'm a GV guy.

Edit: It appears to be a V-6! No? OH! the in'line is a 2.5 as well!

I also concur on the location of the sensors per both our posts.

While waiting for the new sensors to arrive I went and got that second opinion. You were right, only one is testing bad. Sensor 1, bank 1. Also getting a error code P1443 EVAPORATIVE EMMISION SYSTEM CONTOL VALVE. I would think these these are somehow related problems. Any chance these things are covered under that fabulous warrantee they advertize? The car has 65K, bought in Aug. 04


PS: I bought the tools recommended.

FYI: I do have the inline 6 - 2.5L engine in the Verona

Isn't your warranty period 36,000 miles or 3 years? If so, and you are not covered by an optional extended warranty, you're SOL unless there is an (unlikely) recall that covers repairs.

My guess is that the two code probs/components are not related. But that is an educated (gut) feel.
