On my 2000 Town Car, there are four sensors...one on each exhaust manifold before the catalytic converters and then two immediately behind the catalytic converters. The sensors are not difficult to reach, but the connectors they plug into are very hard to get to for the two front sensors.
The front oxygen sensor is located on the exhaust manifold of the BMW 318ti. The rear oxygen sensor is located in the head pipe.
Right in front of the cat converter. Left or right side
There are two oxygen sensor, follow the exhaust coming out of the engine. one in the front and one in the back of the engine. if you engine code p0135 bank1 these is oxygen is located between firewall and engine. or p0755 oxygen located in front of the engine
oxygen sensor on 2.0 is located on the exhaust pipe on v6 it is located in front and rear exhaust manifolds
On the 98 u have two oxygen sensors an upstream and a downstream. The upstream oxygen sensor is located closer to the front of the truck by the transmission. The downstream oxygen sensor is located on down torwards the back of the truck along the side of the frame.
It is in the front of the catalytic converter.
The front oxygen sensor on the 4.6L is located in the exhaust manifold before the catalytic convertor.
Both oxygen sensors are located on the catalytic converters. Sensor 1 is in front of the front converter and sensor 2 is either at the rear of the front converter or the front of the rear converter. They are only a foot or so apart.
The only oxygen sensor is screwed into the front of the catalytic converter.
In the Exhaust manifold at the front of the engine
Both o2 sensors are located on catalytic converter. Sensor closest to front of car is upstream sensor. Sensor closest to rr of car is downstream sensor.
It is located just in front of the catilytic converter by the muffler
