I'm glad to hear that you were able to solve the issue with your Vauxhall Mokka displaying the P0171 trouble code, which indicates a system too lean condition on bank 1 of the engine. Clearing the code and performing a few ignition cycles (switching on and off) can sometimes resolve a temporary problem or a minor issue. However, if the code reoccurs, it's essential to diagnose and address the root cause of the lean condition to prevent any potential long-term issues with your vehicle's performance and fuel economy.
If the P0171 code comes back, you may want to consider the following steps:
Check for vacuum leaks: Inspect the vacuum hoses, intake manifold gaskets, and other components in the intake system for any cracks or loose connections that could allow excess air to enter the system.
Mass Airflow Sensor (MAF) Cleaning: A dirty or faulty MAF sensor can sometimes cause a lean condition. Try cleaning the MAF sensor with specific MAF cleaner spray, following the manufacturer's instructions. If cleaning doesn't work, consider replacing the MAF sensor.
Check for exhaust leaks: Examine the exhaust system for any leaks that could result in false readings of oxygen levels in the exhaust gases.
Inspect the fuel delivery system: Check the fuel pressure and ensure that the fuel injectors are functioning correctly. A weak fuel pump or clogged injectors can lead to a lean condition.
Oxygen sensor replacement: The oxygen sensor on bank 1 might be faulty. Replacing it may resolve the issue if it's not providing accurate readings.
Throttle body and idle air control valve (IAC) cleaning: Carbon buildup in these components can disrupt airflow, leading to a lean condition. Cleaning them may help.
Consider a professional diagnosis: If you're unable to identify the problem or if the code keeps returning, it's advisable to take your vehicle to a qualified mechanic who can perform a comprehensive diagnosis using specialized tools and equipment.
It's essential to address the root cause of the problem to ensure your vehicle runs optimally and doesn't experience long-term damage. Always make safety a priority, and consult with a professional if you're unsure about any aspect of the repair process

I have just p0171 code is the same or it has to write bank 1

[@sanumotorswithcharlie]

The P0171 code is a generic OBD-II trouble code that indicates a lean air/fuel mixture condition on bank 1 of the engine. When you see this code, it typically means that there is too much air and not enough fuel in the mixture being delivered to the engine cylinders on bank 1.
Bank 1 refers to the side of the engine where cylinder 1 is located. In most vehicles with inline engines or V6/V8 engines, bank 1 is usually on the same side as cylinder 1, and bank 2 is on the opposite side. However, it's essential to check your specific vehicle's service manual or consult a mechanic to confirm the location of bank 1 in your particular vehicle.
So, in most cases, when you see the P0171 code, it is implicitly referring to bank 1. However, it's always a good practice to verify the specific details for your vehicle to ensure accurate diagnosis and repair.
