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.

The code will tell you which oxygen sensor is causing the light. If the light is still on you can take the car to Autozone and they will read the code for you for free. Mark down the code and report back here.

Your car has 2 O2 sensors. One is on the exhaust system on the front of the engine. The second O2 sensor is underneath the car, just behind the converter.

Incidently, you have an I4 (inline) engine, not a V4.
