I cannot get my car to pass the California smog inspection.

What is your question?

The computer is having trouble recognising sensors and as a result the engine light will not turn off all the time and when it does turn off, the computer still does not recognise this(the sensors). The ABS module/brake light will not go off. The odometer will not work either, which affects engine idle. I have been all over the place in our area trying to get help with this problem so my car can pass the annual smog inspection,I have spent a lot of $ but have gotten no solution to the problem. Time is running out. If anyone reading this has any answers, please let me know. Thank you
