P2097 Land Rover Code - Post Catalyst Fuel Trim System Too Rich Bank 1

Quick Answer

This fault code is stored in the Engine Control Module (ECM) when the ECM is no longer capable of controlling the air-fuel ratio. Common causes include Faulty Catalytic Converter, Exhaust leak near O2 sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What it means: P2097 Land Rover indicates Post Catalyst Fuel Trim System Too Rich Bank 1.
Common causes: Common causes include Faulty Catalytic Converter, Exhaust leak near O2 sensor.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2097 Land Rover Description

This fault code is stored in the Engine Control Module (ECM) when the ECM is no longer capable of controlling the air-fuel ratio. For correct operation of the Catalytic Converter, the ECM is required to keep the air-fuel ratio (AFR) at approximately lambda 1, this equates to an AFR of 14.7:1 by mass. This is achieved by trimming the fuel mixture to the required amount to cater for slight anomalies during normal operating conditions. However, when a fault causes the fuel trim to exceed a predetermined level the malfunction indicator light is illuminated, and a limited operating strategy is employed. The pre-catalyst exhaust gas oxygen sensor is the primary component used for calculating the fuel trim once the system enters closed-loop control. The fuel trim data can be displayed as a percentage, either positive or negative.
Under this condition, the fuel trim data will display a negative value. The ECM will decrease the injection duration to counteract the excessively rich mixture. This fault can be stored due to a faulty coolant temperature sensor, excessively high fuel pressure, or a faulty fuel injector.
The fuel trim is monitored under various loads and conditions. If a load or condition is included in the fault code this can be an advantage during diagnosis. Normally a code set during idle or light load is relating to an air leak. And a code set during high, or part load can be a fueling issue or an erroneous sensor signal.
