Try loosening the exhaust flange bolts. Take it for a drive and see how it runs. If it runs better then prob your CAT. Also you might have just knocked off a wire/vacuum line last time you were under the hood causing your code 23 |

23 is the Intake Air Temperature sensor mounted on the back of the air cleaner. 13 is the Oxygen sensor Might be a bad ground causing both codes. |

Just because the ECU is sending a code for the oxygen sensor, doesn't necessarily mean that the sensor it bad. I've seen instances where the computer throws a code for a sensor and the sensor is still good. A code can mean that the computer is getting a reading from a sensor that is outside normal parameters. That can be secondary to another problem. My Subaru did that a while back. It was sending a code for something else and it ended up being the knock sensor. I replaced the sensor, and the other codes went away. Check all your vacuum lines and wires and make sure everything is plugged in properly. |
