Land Rover OBD-II Trouble Codes ------------------------------------------------The diagnostic trouble codes (DTCs) P2A00, P2A01, P2A03, and P2A04 are related to issues with the oxygen (O2) sensors and potential exhaust system problems. Here's a breakdown of each code: 1. **P2A00 - O2 Sensor Circuit Range/Performance Bank 1, Sensor 1:** - This code indicates a range or performance issue with the oxygen sensor (Sensor 1) in Bank 1, which is usually the pre-catalytic converter sensor. 2. **P2A01 - O2 Sensor Circuit Range/Performance Bank 1, Sensor 2:** - P2A01 points to a range or performance issue with the oxygen sensor (Sensor 2) in Bank 1, typically the post-catalytic converter sensor. 3. **P2A03 - O2 Sensor Circuit Range/Performance Bank 2, Sensor 1:** - This code indicates a range or performance issue with the oxygen sensor (Sensor 1) in Bank 2, typically the pre-catalytic converter sensor. 4. **P2A04 - O2 Sensor Circuit Range/Performance Bank 2, Sensor 2:** - P2A
