The P1170 code in a 2003 Land Rover Range Rover indicates a problem with the fuel trim system, specifically related to the bank one oxygen sensor. This code suggests that the engine control module (ECM) has detected an issue with the air-fuel mixture, leading to an imbalance that could affect performance and emissions. It’s advisable to inspect the oxygen sensors, fuel injectors, and air intake system to diagnose and resolve the underlying issue.
