Hey folks! I own a 2010 Dodge Ram 1500 - 4.7litre 4x4 and have had very little problems with it up to now. Recently my check engine light has been coming on, when I pulled the code it read - P-2097 - catalyst fuel trim - system too rich bank 1. Any ideas of where I go now?

 

Check the wiring to the sensor first, make sure the connection is clean and tight. Clear the code. If it comes back, replace the sensor. Do you use Bosch sensors... NTK or Denso.

 

Thanks for the tip! I will check the wiring today. May be the problem as I just replaced the exhaust manifold the other day and had the oxygen sensor disconnected.

 

That should have been: "Do NOT use Bosch Sensors......" Darn keyboard.
