Bank 1 sensor 1 in a 2011 Ford F-150 is the oxygen sensor located upstream (before the catalytic converter) on the passenger side. Bank 1 refers to the side with cylinder #1. If this oxygen sensor malfunctions, it can disrupt the fuel delivery and combustion systems, affecting the air-fuel ratio. This can lead to decreased gas mileage due to either a rich or lean fuel mixture. Driving with a faulty O2 sensor is possible, but it is advisable to replace it promptly to avoid increased fuel expenses and potential damage to the catalytic converter.
In the 2011 Ford F-150, the sensor for bank 1 can be found on the right side of the truck, specifically on the passenger side.
Programs that have low viewership and poor financial performance are referred to as "lean and bank 1".
