Those types of codes seem to trip easily. If nothing is malfunctioning, I ignore them just like the Check transmission mystery beeps. No idea how long they take to clear themselves

Fair enough but what about the inertia switch anybody ever had an issue with that before and it's staying in an open loop fuelling map?
