Codes P0130 and P0133

[badcompany87]

Hey Nation
I had posted earlier today about my CEL coming on, well I got the codes read and I came back with two: P0130 and P0133. From what I understand it's the O2 sensor at the exhaust manifold right? If anyone else has had these codes, how did you fix it? Could it be something else besides a bad sensor, like a bad connection? How could I check the connection? I might end up replacing it, has anyone replaced there's and if so I'd appreciate some pointers . Thanks again nation.

yes, both those codes refer to the manifold o2 sensor. You can check the connector first, clear the code and retest. Basically P0130 is if the sensor remains .40V or more or .55V or less. P0133 has to do with response time for the sensor voltage output to change from rich to lean or lean to rich is more than 1 second. Both when engine is warm.

Either way sounds like the sensor isn't working at all.

Hey thanks for your help man, I have a new sensor on the way.
