1998 Ford Ranger oxygen sensors go out every 3 months puts out codes po171 po174 each time what could be causing sensors to go out?
It's important to buy genuine Ford parts. If you are not, this is probably the reason it continues. Also, check the reader on your mass air sensor (it's a wire). If it has crud on it, it will tell the engine that there is not as much air going through it then there really is and the motor will run lean.

How many 02 sensors does a 1999 Ford Ranger with a 4.0 engine have?
Well, honey, a 1999 Ford Ranger with a 4.0 engine typically has two oxygen sensors. One is located before the catalytic converter (upstream sensor), and the other is after the catalytic converter (downstream sensor). So, there you have it, two sensors keeping an eye on that engine of yours.

How many dioxide sensors on a 19994.0 L Ford Ranger?
The 1994 Ford Ranger typically comes equipped with one oxygen sensor, which is responsible for measuring the oxygen levels in the exhaust gases to help optimize fuel efficiency and emissions. However, some models may have additional sensors depending on the engine configuration. If you're referring to carbon dioxide (CO2) sensors, vehicles generally do not have dedicated CO2 sensors; instead, they measure oxygen and infer CO2 levels based on combustion efficiency.

Is it possible to clean the oxygen sensors of a Ford Ranger XLT 1994 or should they be replaced?
As far as I know they can not be cleaned. Must be replaced.
Where are located the o2 sensors in a ford ranger 99?
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.
