Screwed into the exhaust system. Start at the exhaust manifold and work backward until you find one or more O2 sensors.
the O2 (oxygen) sensor on a 93 gmc is in the left down pipe of the exaust Y pipe
Oxygen sensor
Screwed into the exhaust pipe.
no the primary one is the one closest to the engine
It's threaded into the front of your exhaust manifold.
It's a code for the oxygen sensor.
Back side of the engine....mounted in the exhaust manifold.
engine light comes on and off. when light is on it hesitates and transmission slips. what could cause that on a 93 F150
Need a little more information. there are a number of reasons why your cougar would run rough. Anywhere from the mass oxygen sensor to the idle control sensor, oxygen sensors and on and on.
I believe there is an oxygen sensor in each of the exhaust manifold outlets ( 2 ) on a 1993 Ford Ranger 4.0 liter
well on a 93 i would suspect u only have one which normally is in front of the catalytic converter on ur exhaust piping Engine-------o2 sensor--catalytic converter----muffler--exhaust tip in that order
It has 1 O2 sensor located on the exhaust manifold befor the catalytic converter
