Hell, I have a 98 Corolla 159,000 miles...In Nov 2019 I did have my Check Engine Light, I changed the Front O2 Sensor (had to disconnect battery), Light went away, bought the car for emissions testing 2 weeks later, but received an ODB Readiness Fail (garage said computer wasn't ready), I went in the middle of December, received the same reading....Today Jan 13th 2020 I have driven the car more then 500 miles since November, No CEL, and yet today I received the SAME>..ODB READINESS FAIL...Some "readiness monitors on Emissions stated Not read etc....what gives? How can I fix this? thanks
