Troubleshooting the Land Rover Discovery P2195 Error Code
Encountering an error code in your vehicle can be worrying. The P2195 error code on a Land Rover Discovery indicates a specific issue that needs attention. This guide will help you understand what P2195 means and how you can address it, whether through DIY methods or professional help.
What is the P2195 Error Code?
The P2195 error code is an OBD-II (On-Board Diagnostics) code that signifies "O2 Sensor Signal Stuck Lean (Bank 1 Sensor 1)." This means that the oxygen sensor in bank 1 is detecting too much oxygen in the exhaust before the catalytic converter.
Causes of P2195 in Land Rover Discovery
Several issues can trigger the P2195 code in your Land Rover Discovery:
- Faulty oxygen sensor: The sensor itself may be defective.
- Vacuum leaks: Any leaks in the vacuum system can lead to excess air entering the engine.
- Fuel injector issues: Clogged or malfunctioning injectors can disrupt the fuel-air ratio.
- Exhaust leaks: Leaks in the exhaust system can also cause incorrect readings.

Step-by-Step Guide
- Scan the System: Use an OBD-II scanner to confirm the P2195 code. Note any other codes that may appear.
- Inspect the Oxygen Sensor: Check the condition of the oxygen sensor in bank 1 sensor 1. Look for signs of damage or contamination.
- Check for Vacuum Leaks: Inspect all vacuum hoses and connections for signs of wear or leaks. You can use a smoke machine or listen for a hissing sound.
- Examine the Fuel Injectors: Ensure that the fuel injectors are functioning properly. Listen for irregularities in operation or use a multimeter to check for proper resistance.
- Look for Exhaust Leaks: Check the exhaust system for any signs of leaks, especially near the manifold and before the catalytic converter.
