I have an 06 wrangler X, with only 2 sensors which one is sensor 1 bank 1? Is it the one on towards the front or the one in the back on the exhaust manifold?

Any help would be great? I just got the jeep and I didn't have time to get a manual yet.

Thanks everyone and Merry Christmas.

bank 1 is cylinder 1,2,3.... bank 2 is cylinder 4,5,6

I believe you should have 4 sensors 1 before each cat and one after each cat (both cats are on the downpipe)

There are 2 types of TJ's. "Cali" versions have 4 sensors, the rest have just 2. The cats you are describing are pre-cats, the actual cat is under your skid plate before the muffler.

i always use the mechanics view. example is the left side of the engine is left looking at the front of the engine from the bumper ....so bank 1 sensor 1 is the left side of the engine looking at the engine from the bumper and the first sensor you can see from the exhaust manifold down.

I get that, but from that view the sensor would be on the right. At least that's where they are on the 2 4.0's I've dealt with.

No. Always as sitting in the driver seat. Left is driver side, right is passenger side. Just ask this mechanic, or look in any service manual.

No competent mechanic would agree with that.

Bank #1 is the bank that contains the #1 cylinder. Makes no difference which side of the engine it's on.

Yep left side is the drivers side, and has always been so. I deal with that every day, folks come into the shop and I have to question them as to what side they need parts for. Their right is almost always the "other" right.

I thought it was the front sensor and that is the one I changed. Now it is still throughing a p0132 code. For $25 dollars I will be changing the other one.

I have an I6 not the california model. SO I only have 2 O2 Sensors.

Thanks everyone.

I just got to where I use the "pass or driver" side wording. If i start saying left and right most my customers would have the exh coming out above the headlight.

You will be wasting $25 and you won't solve your problem.

You might want to check the wiring associated with the #1 sensor.
