Can anyone tell me where the O2 Sensor is Located on the 2000 SL2 DOHC? I need to replace it. Are there any special tools that I need?

Thanks in advance.

Stick

 

There are 2. One is in the exhaust manifold the other is down stream in the exhaust pipe, I believe after the cat. Boxend wrench should do fine, but they do make a special socket for them. Why do you need to repace it?

 

Trying to eliminate codes. I wonder which one is making the code?

What codes are being set ?
This might help do you have a scnner that can watch the O2 sensor voltage?

 

Thank you for the link and tip. I most likely will replace both of them if they are readily accessible. No scanner available.

 

Repacing them won't hudt anything, but why would you replace the sensors?
What pointed you in that direction?

 

Wow! Napa says $94 for the rear sensor and $67 for the front one. The auto shop who did the scan told me the 02 sensor code.

 

that's about the right price, most times it is the front one. It is a crap shoot with out the scanner.

 

post the code or play roulette with your hard earned dollars...your choice
