Check engine light is on!!!
Hey all! I have a 90 4x4 3VZ-E. I replaced my o2 sensor & fuel filter about 2 months ago & about a month after, my Check engine light came on. It doesn't come on unless I'm actually driving it not just at an idle. All the auto parts places don't have the right connectors for the diagnostics computers & the dealer wants $80 for a diagnostic fee!
Any suggestions?????

Try jumping the diagnostic terminals yourself with a paperclip. Then put the ignition to the "on" position but do not start it up. Look at the check engine light and see if it now is flashing a code. If it is, you can look that code up and see what your problem is. Hope this helps!
