replace oxygen sensor for 1999 Camry LE V4

[jliu66]

Hi, My friends,

I have a 1999 Camry LE V4. I could not pass the inspection because of enigne light is on. I asked one guy in garage to ckeck out and code reader says it is oxygen senor problem. I forgot to copy down the code ID.

I heard that there are two (2) oxygen senor for LE V4. How can I figure out which one is bad? How can I locate the oxygen senor nearby the engine? I check the location of oxygen senor for my car using the picture posted here for 1996 Camry. But it looks like the location is different. Is it possible for sprak plug to cause the engine ligh on or something else or it is just because of oxygen senors?

Can anyone help please? Thanks in advance.

You have an inline four cylinder (I4 not V4), in order to find out which sensor is bad you need to get it scanned again. Try a place like auto zone they should do it for free.
