Yes, a clogged IAC (Idle Air Control) valve can potentially cause a bad O2 sensor code on a 2003 Chevrolet Venture. If the IAC valve is not functioning properly, it can lead to irregular air-fuel mixtures, which may result in incorrect readings from the O2 sensor. This can trigger a check engine light and set a code related to the O2 sensor. However, it is essential to diagnose the vehicle thoroughly, as there could be multiple factors contributing to the issue.

There are several things that can cause a rich condition. To eliminate the guesswork it would be cheaper to have a shop diagnosis the problem. The map sensor and the fuel pressure regulator are 2 things that can be the cause.
There is a low level sensor in the side of the oil pan. It is either stuck or defective.
Transmitions are complicated systems which have many parts. It could be broken, the filter cloged or low on fluid.
