When I do the 3 time key turn thing.. I get these 2 codes. One is power loss (I'm paraphrasing) like when you disconnect the battery. But My clock, etc have no memory loss. The second code, 21 is for a bad O2 sensor which I change about 6 months ago.
Is it bad wiring maybe? What should I check for?
Posted a while ago but rec'd no response. Please help.
thanks in advance for any info which can help,
I would pull the battery cable off for 15 minutes or so to reset the codes and see what happens.
