2002 Hyundai Elantra that says my on board computer is not ready to be tested. Emission results are: readiness- fail, monitor comprehensive- not ready, monitor EVAP not ready,monitor O2 not ready.


Did you recently clear the trouble codes or disconnect the battery? Once all codes are cleared, the computer will not display systems 'ready' until they go through an evaluation cycle. Some of the systems require a certain number of drive cycles before they will display 'ready'. A drive cycle is usually starting the engine from a cold start (based on coolant temperature) and driving until certain conditions are met. I don't know what the requirements are for your car, but my 2003 pickup truck requires more than 10 drive cycles before it will make the O2 sensors and evaporative emissions 'ready'. Most states only require that a certain number of systems are showing 'ready' to pass emissions certification.

Fix a system monitors" not ready" reading during emmissions test


Hi Paul@ FIREFOX,
The most common cause is the engine is not upto working temp.failing this you will need to use an O.B.D 2 meter to pin point fault this will flag up a fault code it works out alot cheaper than changing parts to cure the fault hope this helps....

My hyundai sata fe 2005. was driving and sudenly lost all gears. no warning. foward and reverse. puleed to side of road. shut off checked for leaks none. turned back on drove fine for a few hundred feet....


Some vehicles are made with built in safety features to either not allow the vehicle to start or move if something serious is wrong. Don't know about the exhaust emission but could be in computer software to disable in case of excess emission. Could just be a bad O2 sensor. Need to fix the emission code problem, reboot the computer and try again.

Tune-up?

You realize tune-ups ended 25 years ago

They only install spark plugs,there hasn't been
any tuning in decades,that is what the cars computer
sort of does.
