dfalk Posted December 29, 2008 Share Posted December 29, 2008 So my check engine light has been coming on for a day, goes off for a day, and so on for the past week or so. I pulled the codes and I got a P0691 - Cooling Fan 1 Control Circuit Low P0131 - Front O2 Sensor Low Voltage I have no idea what these mean. Any ideas on what I should be looking for? Also I notcied my MPG has dropped form 24 to 16. It has been very cold outside, like -10 degrees, and I start my car for like 10 min before leaving. So I dunno if the cold would drop it that much or if the CEL has something to do with it. Its an '05 2.5i. Thanks Derek Link to comment Share on other sites More sharing options...
Bdubs Posted December 29, 2008 Share Posted December 29, 2008 P0131- Your 02 sensor has probably gone bad, or possibly the wires have melted or been disconnected giving you a fault. Either way, your best bet would be to buy a new one. P0691- Check your relays and your fuses, chances are one is no good. Link to comment Share on other sites More sharing options...
