P2000 NOx Trap Efficiency Below Threshold (Bank
This code usually indicates a faulty oxygen sensor(s). However, in some instances it can also be used for a faulty catalytic converter as well, since the O2 sensors are located on the exhaust system along with the cat. converter(s). You should check your O2 sensors before replacing the catalytic converter. Here is a guide on checking these sensors.
All engines run on a optimum fuel to air mixture called "stokiometric" which means chemically balanced. This balanced fuel to air ratio is 14.7 to 1, 14.7 parts air to 1 part fuel. The oxygen sensor is created using the active chemical such as zirconium, electrochemical (also known as Galvanic), infrared, ultrasonic and very recently laser. When a lean mixture code is detected by you or a technician the first tendency is to replace the oxygen sensor. The best way to check the operation of the sensor is to run a simple test. No matter if your engines oxygen sensor has one wire or four there is only one sensing wire that feedbacks information to the PCM. To find this wire you will need a car repair manual. If a trouble code is present that pertains to a oxygen heater sensor failure, replace the sensor to repair the problem. A oxygen sensor must be warm before it will operate properly.
Warning: If a malfunction exists with related components such as an engine misfire or engine vacuum leak do not perform this test. The oxygen sensor to designed to operate within a particular range, if this range is exceeded the sensor will give the appearance that it has failed.

P0171 - System Too Lean (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
A code P0171 may mean that one or more of the following has happened:
P0174 is identical to P0171, except it indicates the problem exists on Bank 2 as well.

A green LED indicates system faults
Steady On: System OK
Steady OFF: Board control fault or no power applied
1 Flash: Ignition failure (control in one-hour lockout)
2 Flashes: Pressure switch fault, fails open (switch is
3 Flashes: Limit switch open (main or auxiliary)
4 Flashes: Pressure switch fault, fails closed (switch is
A yellow LED indicates flame status
Steady on: Normal flame is sensed
Flashes: As flame weakens, frequency of LED flashes
