My 95 E320 has a manufacture date of 01/95 is it ODBII? Where is the connector? The reason I ask, is that yesterday after the drop in temperature, my check engine light is on. Here in Texas they plug into the ODBII connector if you have one to check the faults for vehicle emissions testing. I have to have my car tested this month... I have access to an ODBII reader, and would like to check it myself, and fix if possible. Car has about 85K on it, and I think it may be the O2 Sensor, but want to be sure.
