Next, they check if the code is present on both sides or if only one side of the engine is running rich. So I popped the hood and fired up the engine. As propane is introduced, the mechanic should see a reaction from the O2 sensor indicating a richer air fuel mixture has been introduced. P2197 can cause serious internal engine damage. The door locks lock and unlock to confirm the new code is programmed. If your F150 is a 2010 model and has the 4.
The list of automotive Makes at the right edge of the screen. Technicians will check for ground, short to power, open circuits, etc. How to Fix The most common repair for this code is simply replacing the O2 sensor or repairing the vacuum leak. Expedition Engine Compartment Popping the hood on the Expedition and this is what you see. However it's not as bad as it looks.
Most any scanner would also do the job. The existing code does not need to be erased to program a new code. While not car-threatening, it's good to take care of this right away to improve gas mileage. You could hear this one with the engine running. Continue driving and see if the check engine light turns off. Common mistakes when diagnosing the P2197 code The most common mistake with most O2 sensor codes is to change the O2 sensor as soon as an O2 code is present.
But other components can create conditions to set this code. The outer surface of the sensor element is exposed to exhaust gas. These systems have many points where gaskets and seals are used to create a sealed system. The most common is a vacuum leak in the intake manifold on bank 2, in the case of this code. I tend not to want to use my phone for that stuff, but they are cool and very inexpensive. If there are no obvious signs of a vacuum leak, the mechanic should suspect a faulty O2 sensor. Unlike the cheaper Haynes and Chilton manuals that cover multiple year models, leaving the exact information you need to fix your car, these professional manuals cover your exact year, make, model.
Need help with a P2197 code? It detects the amount of oxygen in the exhaust gas compared to the outside air.
