Help! My 99 Elantra will not pass inpsection because: O2 sensor heater circuit bank 1 Sensor 2 O2 sensor circuit low Voltage bank 1 sensor 2 Vehicle speed sensor "a" range/performance.
What does this mean? My mechanic replaced the O2 sensor 2 and repaired an exhaust leak that I had, but the same codes are coming up and now he says I have to take it to a dealer. I do not trust the dealer and have been trying to find the possible cost of the speed sensor, but it seems no one sells them.
Can anyone help?
