P2000
NOx Adsorber Efficiency Below Threshold Bank 1
DTC P2000, sometimes indicated as P200000 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing nox adsorber efficiency below threshold bank 1.
The NOx adsorber efficiency below threshold bank 1 fault is caused when the NOx adsorber is not able to remove enough NOx from the exhaust to meet emissions standards. This fault can be caused by a number of factors, including a clogged filter, a faulty sensor, or a defective adsorber.
There are a few things that can be done to try and fix the fault. First, the clogged filter should be cleaned or replaced. If the sensor is faulty, it should be replaced. If the adsorber is defective, it should be replaced.

2007 DODGE RAM 2500 with 591.0 miles
Within two weeks of purchasing the 2007 Dodge Ram 2500 slt reg w/ turbo, (delivery date of 07/12/07) the check engine light came on. The dealership we purchased from said not to worry about it unless it came on permanently. On 07/27/07, took truck in for left speaker issue & check engine, they just cleared the codes for the check engine light. Took back 08/27/07, engine code P254A, cleaned sensor. Called dealer 09/15/07, "check engine' light back on for longer than 3 days, they said not to worry about it as long as the light was not flashing or staying on. Called them 09/27/07, took truck back 10/03/07, check engine light codes P2262, they performed carbon clearing procedure. Took truck back on 10/08/07, they did not make note of check engine code on work order, but they wrote turbo assy. Failure, replaced and cleared code. On 11/30/07, check engine light on again, performed emissions recall and sensor and reprogram ecm. During 12/07 thru 01/08, check engine light still remained on most of the time, but was extremely busy working plowing snow and could not take back until 02/01/08, engine code P1451. They did "flash ecm as per tsb. By this time thoroughly upset with truck, manufacturer, etc. Engine light remained on again 03/08 through 06/08. On 07/03/08 took back again, engine code P2262 and P2000. They performed computer update. Again light on almost from onset of last visit. On 08/19/08, engine light, code P2000, they performed flash update to engine control. Picked up truck on 08/19/08, and check engine light came on 08/21/08. They could not get truck in until today 08/25/08. Truck still there tonight as the code came up that stated they needed to once again clean and they could not get it done today. (note: they did not tell me over the phone what code came up, just that they had to clean the turbo. We, my dad and i and my mom have lost considerable money in lost work time in having to take truck for repair, let alone the inconvenience of it all!
