How Do You Replace The Bank 2 Sensor 1 O2 Sensor On A 2001 Ford Ranger?
The bank 1 sensor on your 2001 Ford Ranger gathers information about the vehicle’s emissions. This information is then sent to the Ranger’s computer, called an electronic control unit, or ECU. The ECU then adjusts the air-to-fuel ratio to optimize fuel economy and horsepower output. When this sensor fails, you will experience a dramatic decrease in engine performance. The only solution to this problem is to replace the O2 sensor. Replacement sensors can be purchased at most auto-parts stores. Open the hood of your 2001 Ford Ranger and remove the two bolts that hold the heat shield to the exhaust manifold on the front of the engine, using a socket wrench. Pull the heat shield off the front of the engine to expose the exhaust manifold. Reach down into the engine bay and unplug the electrical connector that runs to the O2 sensor, which will look like a plug stuck into the exhaust manifold. This is the bank 1 O2 sensor. Unbolt the bank 1 O2 sensor using a socket wrench and O2 sensor socket
