Question about 2001 Dodge Neon
I have codes coming up P137 , P139, P140, P141 all are from Bank 1 Sensor 2...
Where is the sensor located ?
I had the car checked before and was told the Cat. converter was clogged...I had it replaced... the check engine light comes off and on every several days...
That is the O2 sensor right behind the cat. converter. When the cat is clogged it can shoot contaminates in the O2 sensor so sometime just cleaning the sensor will make it work again, if not it will need to be replaced. Mark - ABKS
