O2 sensors are always threaded right into the exhaust pipe. Follow the pipe until you see the sensor. If this model has more than one, you may need to know which bank your looking for (V6 only) and whether its the upstream or downstream sensor. Bank 1 is whichever side of the engine cylinder 1 is on. Upstream is before the catylitic converter and downstream is after it.
I'm not a mechanic / technician but on a 1988 Ford Ranger there might be ( 1 ) oxygen sensor ( upstream sensor )
the o2 sensor is located on the exaust manifold
The O2 sensor after the catalytic converter.
P0153....O2 Sensor Circuit Slow Response (Bank 2 Sensor 1)
usually bank 1 is the bank with # 1 cylinder in it and sensor # 1 is the front o2 sensor(usually in the manifold). You will need a O2 sensor socket or a 22mm wrench or deep socket.
CHECK FUEL PUMP REGULATOR, I HAD THE SAME.
Wher is the o2 sensor on a 2006 ford f150
if there is an 02 sensor in your car, then someone put it in there. you can't have one as a stock part. considering it's a top-heavy vehicle.
Trouble code P0133 means: O2 sensor circuit,slow response (bank 1,sensor 1)
If it's like a 1991 Ford Explorer ( with the 4.0 liter V6 engine ) It has ( 1 ) oxygen sensor
Buy a Haynes or a Chilton manual. They will have all the wiring daigrams that you will need.
Bank 1 is the passenger side of the engine in your 3.0 liter Ford Ranger Sensor 1 ( upstream sensor ) is in the exhaust before it enters the catalytic converter ( either in the exhaust manifold or exhaust pipe )
