Hello everyone,

One day i started my car the day after an Oil change I recieved a CEL. I used a OBD2 scanner and it read P0132 for O2 Sensor High Voltage. I done my research and read that this is caused because my engine is running rich, therefore its causing a high voltage reading.

My car feels really weak, and idles roughly like its about to die. Acceleration is poor as well. I know this is caused of the CEL for running rich.

So my Question is, What can cause this CEL to throw? I would clear it and it would come back a couple hours later. Could it be the O2 sensors? And how many O2 sensors are in the S2000?

I also forgot to mention that i have a CAI and I notice its not "sucking" in as much air as before. It has a low sucking tone ever since the CEL came on. Could it be that the air filter is clogged up and preventing the engine from recieving enough air and too much fuel to run Rich? Thanks so much!

Check connector and wiring going to primary heated O2 sensor (HO2S on 2000-05 models). AKA: Air/fuel ratio sensor on 2006-08 models.

Sorry i I didnt have a chance to reply my solution but turned out my Primary O2 sensor was shorted out, therefore causing my car to run bad with the CEL coming on. Changed it and my car idles fine and CEL doenst come back anymore! thanks!
