I can get one at Autozone for $90 without a wiring harness. The one with the wiring harness is like $180. Can you use the old wiring harness on the old one and save $100. If you can how hard is it to put the old harness onto the new 02 sensor. Or should I get one from honda for like $250? Also what does wideband mean? Will I need an OBD1 or OBD2? Im suppossed to get an upstream OE 02 sensor?

 

you should be able to find them for no more than $70 most places

 

are these realitively easy to install, and arent there front and rear o2 sensors? which one pertains to a fuel related issue? thanks

 

If its a 90-95 it should be an OBDI (only 1 o2 sensor) and a 96 and up should be OBDII....that has 2 o2 sensors. I am not 100% on the years but OBDI's have only 1 o2 sensor and OBDII's have 2 o2's

 

Nick H - where are the places that have them for 70 bucks? I'm at 300,000 miles and it's the original sensor still getting around 27 MPG but who knows maybe it could be better with a new sensor, p.s. it's a 93 EX 5-speed.

Thanks!

 

you're right man! 96 and up are OBDII with two o2 sensors, thanks for the help. are these easy to change myself if its on the headers?

 

just to let you know I had a O2 sensor go bad on me. I tried to replace mine with an autozone sensor but it still threw a code. So I had to replace it with a OE Honda sensor.

 

The one in the manifold is easiest, especially if you remove the amnifold for more leverage. The one in the cat is a PITA

 

i bought a bosch o2 sensor from autozone for like 60 bucks... i've had no problems with it

 

bosch o2 sensor hasnt had any problems or thrown any codes?

 

Did u guys buy the one with or without the wiring harness there is like a 100$ difference. What is the one with the wiring harness better quality. Can you use the originally o2 sensor harness? I need one bad its also seeming to make my car run a little different. But I have not checked to see if is throwing any codes. Im just positive it needs replacing.
