For a Ford F-150 ecoboost, the oxygen sensor closest to the engine on the driver's side exhaust, before the catalytic converter, needs to be located. If there are issues with the catalytic converter, it can lead to various problems. One noticeable sign is seeing black smoke from under the hood, indicating a problem. This is not a fire hazard, but it's important to turn off the car right away. You may also feel the engine being sluggish and unresponsive when accelerating, resulting in lower speeds. Additionally, there may be a sulfur or rotten egg smell coming from under the vehicle. Repairing a catalytic converter can cost between $950 and $2500, which is a costly but necessary fix.
In the Ford F-150 EcoBoost, the location of the bank 2 sensor 1 is underneath the vehicle on the driver's side of the exhaust system before the converter.
