My cavalier is showing an diagnostic error code of P0133 which tells me one of my oxygen sensors is bad, but not which one is actually bad. How can I tell without actually replacing one or both?[/quote:83f1d29c0f]


Hello,

Here is the exact code def....

P0133 Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 1)

Which since your vehicle is a 4 cylinder you only have 1 bank. Sensor 1 would indicate the sensor located in the Exhaust Manifold. Sensor 2 would be the next one back.

So you would replace the sensor in the exhaust manifold.

Hope this helped.
