I have a 1995 Nissan 240sx that has the check engine light on. I have gotten the error checked and it come up with Error 33 (Front O2 Sensor). I have had it reset after I changed the sensor. Now, the light is back on and still gives me Error 33. I have been getting it reseted many times hoping it wont come back. I have had this issue going on for almost a month. What could it be and what can I do to fix this issue? Thanks in advance.
