Asked by Jul 28, 2015 at 06:52 AM about the 2008 Dodge Avenger SXT

Question type: Maintenance & Repair

For almost a year now I've been
dealing with the check engine light
on my 2008 Dodge avenger. It keeps
getting the same code which is an
O2 sensor, this has been replaced
three times. The Code gets cleared I
drive out of the shop   And the check
engine light  comes back on, I've
been dealing with the check engine
light on my 2008 Dodge avenger. It
keeps getting the same code which
is an O2 sensor, this has been
replaced three times.  Now my car is
up for inspection and will not pass
because of the check engine light,
what can I do is there any recalls on
this?

Obviously the O2 sensor is not the problem. What is the code number?

Bob is right some vehicles have up to four 02 sensors.

Go back to whoever has checked it and tell them they haven't fixed it yet and they need to rescan it and check for another sensor or 3. Good Luck and I hope they find it for you this time. :)

The diagnostic should read between .45 volts (less than a half volt) when engine is running. . If it's too low the Catalytic converter may not be functioning properly. Be aware when the CEL light comes on your car runs " rich" resulting in lost performance and bad gas mileage

The code is always the same it's the rear bank 2 sensor, which is the one that's been replaced 3 times. All of the sensors have been checked, even the new one is not running that great, just replaced yesterday. I'm being told it may be a wiring problem & that I need to have a dealer look at it. My inspection is up this Friday

The rear bank2 sensor only tells the ecu about catalyst efficiency. I wonder if it is a wiring problem or if the bank 2 is running lean for some reason.

Turns out had to replace the computer, not a cheap fix
