I have an 02 toyota four runner and I got a OBD rejection notice when i went to try to get it inspected , this is in the state of virgina ,The OBD form shows "not ready" in these areas
I hooked a ODBII reader to it and got p0125 closed loop fuel control insufficiant coolant temp
P1135 manufacturer conrolled fuel and air metering
it has a check engine light and the ECT light is lit up
it also will not upshift when it is cold in the morning
my first thought is to replace the O2 sensor , even if it is not the issue after 88000 it would not hurt to have replaced
what do you think ?
