I have a 97 with the auto and a 4.0 with that said my check engine is on and so I went to vato-zone to get it run and the guy said it was the the first o2 sensor and it was the transmission range sensor voltage??? Does anyone know what this could meen? I can fix the o2 sensor no problem but how can I fix the transmission range sensor voltage problem? I have just recently had the transmission not go into 4th on the freeway and I wonder if this is related to the range sensor thing. Any ideas?
Oh ya and can I erase codes my self without a scan tool?
