My 1997 Dodge Ram just threw a #43 code, does anyone know what that could be?

You either have a lose connection or a bad 02 sensor. If your 02 sensors are original and have over 70 thousand miles on them, then there all bad and need to be replaced.

Yup, new O2 sensor. It's not a huge deal to get it replaced immediately as it won't severely effect the truck, but it'd be something to do sooner than later.
