An oxygen sensor monitor incomplete means your vehicle’s computer cannot determine if everything in the emission control system is functioning well. So, the OBD inspection will be incomplete. If you have a defective unit or the heater circuit is not good enough, it may keep you from getting your monitor ready. The oxygen sensor monitor is a self-ch...
Here are a few reasons your Chrysler, Ford, or GM’s O2 sensor monitor will indicate not ready: 1.

How can I keep my oxygen sensor ready?
First, reset the car’s computer. Then drive your car, covering a distance of 50 to 100 miles. Your monitor needs driving to check the sensors and determine any potential problems.
Will my engine operate in the absence of oxygen sensors?
Your Power Control Module will be unable to determine the fuel to supply the engine if your 02 sensors are not working. But, of course, your engine will operate.
How will I figure out if my drive cycle is complete?
Do not start the engine for at least eight hours. Drive at a steady highway speed for 15 minutes. For twenty minutes, drive with 30 seconds of idle time in between.
