2005 Town & Country 6 cyl. Automatic FWD 44,600mi. Engine Codes

I have an engine light on so I cycled the key on and off three times to get the codes P 2097 -and P 0138. Could you tell me what each one of these are implying? Thanks so much for your time.

P0138 is a faulty Oxygen Sensor. There are two--the Upstream Sensor mounted on the Exhaust Manifold and the Downstream Sensor mounted on the Cat Converter. Unfortunately, P0138 doesn't tell you which one is bad.

I can't find any record of a P2097 code.

Here is a link with the code descriptions:

P0138 is a high voltage output on bank 1 sensor 2 (bank 1 is the same side as #1 clyinder, sensor 2 is after convertor) I would check for a rich fuel/air mixture causing the cat to overload.

P2097 is cataylitic convertor related.

Hope this helps

P0138HO2S 12 Circuit condition (Heated Oxygen Sensor Bank 1 Sensor 2)
– The powertrain control module uses the oxygen sensor to calculate the air/fuel ratio in the exhaust.



P2097ChryslerDownstream Fuel Trim System 1 Rich or Lean
– The ECM has detected a fault with the downstream O2 sensor
Bank one is the bank with cylinder #1 on it.

Not much new here. P0138 flags the downstream HO2 sensor. That's aft of the converter as stated. Just a couple of websites for future reference: http://www.obd-codes.com/p0138
