I was looking in my Chilton book at the engine wiring schematic for a 1993 Ford Ranger 2.3 liter 4 cylinder and I only see ( 1 ) heated oxygen sensor
According to my Chilton repair manual engine wiring schematics there is ( 1 ) on the 4 cylinder and ( 2 ) for the V6 engines in a 1994 Ford Ranger
They are either in the outlets of the exhaust manifolds or in the exhaust pipes close to the engine
Four cylinder engine? 2 sensors, one before the cat and one after.
If you have a 4 cylinder engine, you will have two. On a 6 cylinder, you will have four.
A little more information please ( what year of Ford Ranger , what size is the engine ) As far as I know there could be as many as four oxygen sensors or as little as one depending on the year and engine size
According to the engine wiring schematic in my Chilton book : For a 1999 Ford Ranger , 4.0 liter EFI , V6 engine : ( there are 3 oxygen sensors )
On a Ford Ranger ( V6 engine ) Bank 2 is the drivers side of the engine Sensor 1 would be close to the engine before the exhaust enters the catalytic converter
their is more than one oxygen sensor but the one that is probly bad is on the exhaust system. otherwise I would check the map sensor.
It depends on number of cylinders the engine has. 4 cylinder engine has 2 oxygen sensors. V6 has at least 3.
You will find them in the exhaust system.
It just has ( 1 ) oxygen sensor , before the catalytic converter ( upstream )
O2 sensor in the exhaust manifold near the engine
Bank 1 is the passenger side of the engine
its before the cat around the header area
You can find it next to the oxygen wire harness, sticking out of the cylinder head (right side of the engine when you are facing it).
E size oxygen cylinder contains 622 L of Oxygen.
The oxygen sensor on a 2004 Volkswagen Jetta is located in the engine area. It is usually encouraged to warm up the engine so as to ease the threads.
That would be the sensor after the catalytic convertor.
Your engine will have 4 O2 sensors. And all of them will have a different part #, because the connectors are all different.
If your 1988 Chevrolet Celebrity has the V6 engine the oxygen sensor is in the middle of the exhaust manifold nearest the firewall. If you have the 4 cylinder engine the oxygen sensor is located in the exhaust manifold just above the exhaust pipe flange.
Bank 1 should be the side of the engine cylinder #1 is on.
