I'm working on my wifes grandparents intrepid and pulled some codes out of it. I was wondering if anyone knows what the meaning of the codes are. The code are a 51 and a 55. I don't have any where to get my hands on a dodge service manual otherwise I'd look them up myself. Thanks for any help you can give me. I don't think it will matter but the intrepid is a 1995 with the 3.5L engine.

 

In case you missed it, there is a "sticky" on the top of the Tech/General Engine Furum page that list Forum Rules. There is also a link to a message from one of the site Administrators. One point of the link is that post content should be related to ThirdGen 'F' bodies only.

Besides, a Dodge repair manual may be may be written in Japanese, German, Thai, Korean, Sumatra, Pakistani, or whoever they happened to get their vehicle parts from at any given time. I hope you're fluent. It seems only fitting that their coprorate logo is a sheep.


Incidentally:

51 - Oxygen Feedback System Being Latched Lean (Stays Lean More Than 2 Minutes);

55 - Indicates End of Diagnostic Mode

Sounds like it's time to throw away the car and get one with a good oxygen sensor, or replace the oxygen sensor - your choice.
