| Post subject: | Reoccurring Check Engine Light |
I have a 2004 Jeep Liberty Renegade with ~97,000 on the odometer. About a month ago, a few days after I had my clutch bearings replaced, my check engine light came on for the 2,2 O2 sensor; so basically an error with the passenger side O2 sensor after the catalytic converter. I replaced the sensor and after around 50 miles the check engine light turned on again. I then replaced the plugs and got another new O2 sensor and again, after about 100 miles, it’s back on again for the same error code. I have heard talk about this being caused from a failing fuel pump, which is failing to pump enough fuel to the engine. However, this seems counter intuitive, if this was the issue I would assume that both banks would read an error. So, before paying a mechanic to rip apart my rig and repair/replace things that I have already done myself; does anyone have any ideas that might resolve this issue? |

Is it only the MIL (check engine light) or do you have other, assorted indicators illuminating or making noises? |

It's just the standard orange illuminated engine icon, nothing else. |

Bad converter ? |

Yeah, I think the catalytic converter might be an option, drove around with the light on the first time for about two weeks before I had the time to replace the O2 sensor, so my procrastination may have caused me to cook my cat. Also over the weekend, I went to start it and it sputtered and died. Had to wait 5 min before it would fire up... I've never had an issue with it starting before. But I guess when it rains it pours... I’ve never had any problems with the vehicle since I bought it besides the regular upkeep, but this year alone my water pump, power steering pump and clutch and clutch bearings crapped out on me. |
