Is there more than 1 O2 sensor for a Jeep ZJ (Grand Cherokee '93-'98) V8? Is this the Downstream or Upstream of the Catalytic Convertor sensor unit? Or are both the same? Thanks for the info everyone! Definitely should have specified it's a '94 5.2L...

No, there is only the one O2 sensor. It is down stream from the headers just under the right hand back passenger seat just before the Catalytic converter. This sensor is a perfect fit with the connector. there is no modifying required. has worked great for me for the last 4yrs. So I cant complain. Hoped this helped.

Dear Mickey, I'm pretty sure you already got your answer, but for anyone else who does not know who many oxygen sensors your vehicle uses, I found the only reliable way is to inspect your exhaust manifolds top and bottom. They are screwed directly into the manifold itself. Four cylinder vehicles probably have one(1), six cylinder vehicles probably have two(2), I think eight cylinder vehicles can have two(2) or four(4). If you cannot perform this inspection then you won't want to do the job yourself. When working under a car, always support it with jack stands. Don't trust a jack by itself.

Each vehicle is different in the amount of O2 sensors they have. Could be 1-4 or even more.If you know you only have two, the upstream is before the converter and the downstream is after it.You need to know which is bad before you replace it. Most parts stores can scan you vehicle and tell which one is suspect.

This is one of the sensors down stream of the catalytic converter, and yes there are two, one for each exhaust pipe before the muffler. Both downstream sensors are the same.

On my 2000 Toyota Tundra V8, it was the upstream sensor. If the Sequoia has a 4.7L V8, it is probably the same.

I believe it is up stream . the catalytic converter was towards the rear as i replaced the sensor.

there are a total of 4 oxygen sensors on that vehicle, 2 before the catalytic converter for fuel trim and 2 after that monitor catalyst efficiency. Although I believe the front and rear are different.

If your rig calls for a 13477, this IS a 13477. Also, the fitment guide says a 13477 2004 BMW 330xi (an X3). No problem. The pertinent question is whether you are after a pre or post cat sensor. Yes, the sensors before the cat are usually referred to as 'air fuel' sensors, not O2 sensors, but it's not unusual for folks to call all four sensors by the same name. The upstream (first IN line) sensors do sense oxygen, but are of a different construction/type than the downstream O2 sensors. IF you are after a 13477, this is it.

On my car it's on/near the rear exhaust manifold within the engine bay. The 2nd sensor is on the catalytic converter. I bought a new sensor just to be safe when I had this part installed.

upstream is the number 1 sensor it is a air fuel ratio sensor the. down stream number 2 sensor is an o2 sensor #1 is closer to engine these are different and can not be interchanged

I'm not sure if this is for the downstream o2 sensor. Maybe someone else can chime in on that. It's bank 1 sensor 1 near the firewall and you can also use this on the manifold towards the front bumper. They are the same. Yes. This one comes with the wire and plug. Once you are able to break them loose installation is easy.

I can't answer that for you. I put Freedom Performance radius pipes on mine and it has the O2 sensor. I also put a throttle screw adjust on so I could make adjustments without taking off the tank. Go to one of the Raider forums and ask there. Good luck.

No. The oxygen sensor ports are not in this catalytic converter. You either need to use the factory ports or weld on new ones.

I'm not sure how many you would need. The best thing to do is just look. I would assume 3 (one for each downpipe/head pipe and one for behind the catalytic converter). It appears that this part is listed for all of them. Raul, you are thinking of a full-size truck/SUV with a V8. In these, yes, there are 4, but this is because there are two catalytic converters. On the S-series with the V6, there is only one catalytic converter therefore only 3 sensors are needed.

Our Suzuki's V6 has one on each bank of cylinders. It also has at least one other downstream, somewhere. I'm not yet sure exactly how our exhaust system is routed. I know we have two header pipes and two tailpipes, but whether or not there are one or two additional sensors in between (or catalytic converters, for that matter) is a question I'll have to answer when I find the time and energy to get these grumpy old bones beneath the thing. In any case, I'd check elsewhere for information on a particular car model, as this sensor is made to be used on an assortment of vehicles. Kind of like those Takata airbags that are leading to so many recalls, for Honda and many others. Best wishes. Our Suzuki's V6 has one on each bank of cylinders.

According to the Autozone website (I usually check their site, then, buy from Amazon. Autozone wants $56 for this oxygen sensor), this is the upstream (before the catalytic converter) sensor for your Ranger but you would need a different one for the downstream sensor (after the catalytic converter). The downstream sensor is Bosch 15717 but they haave other with varying lengths of wire.
