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.
That Vehicle has 2 oxygen sensors.
My 1995 Ford Explorer with 4.0 L OHV has 2 oxygen sensors (Helpfull)
I'm not a mechanic / technician but on a 1988 Ford Ranger there might be ( 1 ) oxygen sensor ( upstream sensor )
Check
MAF sensors are generally near the air cleaner box.
What is a carbon dioxide sensor?
WWW.MOTORCRAFT.COM shows remanufactured AIR MASS SENSORS ( mass air flow sensors ) for the 3 available engines on your 1993 Ranger , there are no listings for a MAP sensor
only 97 and earlier models have speed sensors
My 1995 Ford Explorer with the 4.0 L OHV engine has 2 , so I'm assuming your 1995 Ford Ranger 3.0 L would also have 2
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.
Their are two sensors located directly behind the front bumper along side of its mounting brackets.
There are 2 heated exhaust gas oxygen sensors , 1 screwed into the outlet on each exhaust manifold on a 1993 Ford Ranger 4.0 L .
