I need to replace the passenger side upstream o2 sensor.

does anyone know the part numbers for this replacement? I found Bosch 15717 and 15718 as well as Motorcraft DY1093.

for an 02 5.4L

Thanks

sorry, haven't gotten on in a while. I've searched some more and can't find anything.

 

That is difficult to believe...

Look up Motorcraft number at www.forparts.com then go buy it.

 

Rock Auto says the fronts are DY835. $47.89. Bosch is 15664 and cost more.

You are looking at rear sensors.

 

thanks for the link, but it runs me into the same problem i've been having. every time i search for something it just floods with information. universal fit, direct fit, alternate fit. what does it all mean?

i know to get bosch or motorcraft, but, of all these parts listed, which can i or cannot use?

 

15664 Oxygen Sensor - OE Type - Exact Fit - Upstream Sensor Two required; 4 Wire; Heated; Check / Replace Interval: 100,000 Miles V8-cc 5.4L FI EngDesg GAS.

glc has the number above.

If your Manifold and Y pipe is OEM, stick with "Exact fit". That's the easiest route. I would replace with the same, either Bosch or Motorcraft; whichever you have currently, -and replace both upstream at the same time for best results. No need to worry about Alternate, Universal, etc, -unless you have a custom set up that relocated bung locations further downstream.

Yea, - "Exact Fit" - Upstream.

 

thank you. i have a completely after market exhaust but the driver side o2 still fit in the new location.

reason i only asked about the passenger side is because i had longtube headers sitting around for a year or two. finally got around to installing them and turns out they didn't fit. had to get the exhaust done so i got shorty headers and everything else had been cut out or replaced already. i had already cut the sensor wires for a TEMPORARY extension installation but that stayed under there longer than i wanted.

again, thanks for the help.
