I have a 1995 SC3, and the CEL came on last night. After I sobered up, I pulled the code, and it is throwing a 21. From what I have searched, there are 3 O2 sensors (two in the front, and one in the rear). Can anyone tell me exactly how to get to the front two?

I am also a Supra owner, and have access to the TRSM (toyota repair service manual) online...has anyone ever posted one for our cars online?

Thanks for the help.

open your hood and look at the exhaust manifold they are right there.

The 3ed 02 sensor is only on California cars. So dont look too hard, you prob only have the 2.

Not to troll your thread, but I hope your car threw the code and you parked it for the night before you got drunk.
