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.
I'm not a mechanic / technician but on a 1988 Ford Ranger there might be ( 1 ) oxygen sensor ( upstream sensor )
In a 1999 Ford Ranger, the oxygen (O2) sensors are located in two primary positions. The upstream O2 sensor is found in the exhaust manifold, before the catalytic converter, while the downstream O2 sensor is located after the catalytic converter in the exhaust system. These sensors monitor the oxygen levels in the exhaust gases to help optimize engine performance and emissions.
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)
o2 sensor Bank 2 sensor 2
That Vehicle has 2 oxygen sensors.
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.
the upstream O2 sensor is directly below thethe exhaust manifold flanges, above the catalytic converter. The downstream O2 sensor is in the exhaust pipe. Disconnect the electrical connectors and screw it out
CHECK FUEL PUMP REGULATOR, I HAD THE SAME.
Wher is the o2 sensor on a 2006 ford f150
There should be 2 (upstream) O2 sensors (one for each bank of cylinders) before the catalytic converter and only one (downstream) O2 sensor after the catalytic converter. All 3 are threaded into the exhaust system.
