is this upstream sensor or downsensoe for 2003 Escort?

Richard, You have to do some research about the sensors that your car is using, in my case (Mazda Tribute 04) uses one upstream and one down with the same Bosh Sensor model.

Single sensor. Put mine in about 2-3 years ago and no issues since. Took approx 1 hr for me and a friend to change in the driveway. Mine were rusted pretty severely. Biggest issue was getting the wiring disconnected without breaking the connectors.

That's exactly the sensor I ordered on Amazon and replaced the downstream oxygen sensor located under the body of my 2005 Honda Civic. It comes with connector so you do not need care about rewiring to old one

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 have a 2001 taco and both of my sensors are on the passenger side. 1 is between the engine block and the first catty converter. the 2nd (sensor 2) is between the 2 catty converters.

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.

If you have the V6, both upstream sensor should be the same. Your diagnostic code should tell you if your problem is bank 1 or 2. I only needed to replace the bank 1 sensor and that solved the issue. Check out this web page for more info, (maybe more than you need, or want). http://www.autoshop101.com/forms/h37.pdf

Hello, Sir;For the UPSTREAM CNG Engine the oxygen sensor part number 13117For the UPSTREAM GAS Engine the oxygen sensor part number 15716For the DOWNSTREAM GAS Engine the oxygen sensor part number 15717 or 15718.Thanks. Hope this information are helpful. Thanks

Upstream sensors are located before your catalytic converter and downstream are located after the converter. Using the diagrams in the repair help section on autozone.com can help a lot.

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 suppose it depends on the vehicle, but in my 1998 Jeep Wrangler TJ, this is the upstream sensor. The downstream sensor is different, and its part number is Bosch 13138, though if you're buying for a Jeep I would recommend you stay away from from the Bosch and go with NTK/NGK. I've been much happier since I switched.

I'm not Sure but there are 4 sensors maybe it isn't in the place where the effected sensor is double check the installation/wiring good luck !!!!!!!!!!!!

Nope- if you drive a 2005 rsx 2.5L try the 234-4354 for downstream or 234-9064 for upstream

The upstream sensor threads into the pipe coming from the engine, closer to the front of the car, and the downstream sensor threads into the catalytic converter, more toward the rear of the vehicle. They are not interchangeable.

This sensor works the upstream sensors closest to the manifold in the V6 models. I believe the downstream sensor requires removing the drivers seat as the plug, floorboard seal and pigtail are different. Google the replacement of the sensor and there are several videos on line.

If it is the 2.0 liter engine the part number for the upstream is Denso #36531PNDA11 if it is the 1.7 liter it will be #36531PLE003

This is downstream. part number 234-4162 is Upstream. The sensor should be universal to CARB requirements.
