I am getting the oxygen sensor not ready code on my Seville. Does anyone know what I should look for? Is the O2 sensor bad or something else setting it off? The car seems to run fine. Thanks for any help!

Re: 1989 Seville code E13 Oxygen sensor not ready
It wont be ready if the engine temperature is not to normal ( 195 to 210 F) Verify that thru diagnostics. 80 to 90 degrees C is the same. Should get there is 5 min. running. Or if the sensor is unplugged!!! it would not be ready. Or, if the sensor is a 2 wire sensor, its possibly not being heated.
Check out the suggestions of Carnut. The sensor may well be faulty and in need of replacement. The manufacturer recommends they be replaced every 30,000 miles. If the O2 sensor is faulty it's costing you money at the gas-pump.
