Neither the tire pressure light nor the broken speedometer/odometer will cause your vehicle to fail the smog inspection. Your KIA can pass the smog check with these lights on. The only light to make sure is not illuminated is the check engine light or MIL malfunction indicator lamp; which is of concern in this case. Since you recently replaced sensors as you've mentioned, the check engine light has turned off more than likely because you disconnected the battery; resetting the computer and clearing the trouble codes.It was the right move, but you now need to drive your KIA through a drive cycle in order for the computer to re-learn/complete the readiness flags (also known as Emission Monitors).
Driving for 200-300 miles over the course of a few days and in both city and highway traffic will accomplish this. In a few days you'll find out if the repairs you made fixed the problem(s) and ensure the check engine light does not turn back on. Your KIA will then be ready for the smog test, and if your planning on
