There are a total of ( 4 oxygen sensors ) according to the engine wiring schematic for the 1997 Mercury Mountaineer in my Haynes repair manual ( 2 oxygen sensors are " upstream " sensors used by the PCM to adjust the air / fuel ratio of the engine ) ( 2 oxygen sensors are " downstream " sensors / catalyst monitors )
ther are 2 oxygen sensors, an upstream and a downstream . The upstream is on driver side of engine exhaust and the downstream is back of catylitic converter agin on exhaust pipe.
There is a total of 3 O2 sensors 2 Upstream and 1 Downstram
For a 1997 Mercury Mountaineer ( 5.0 liter V8 ) ( there are a total of 4 oxygen sensors , 2 sensors that are used with the PCM to adjust the fuel ratio that are nearest the engine on both sides , and 2 sensors that are also called catalyst monitors because they are in the exhaust after the catalytic converters ( downstream sensors ) On the passenger side of the engine in a Mercury Mountaineer ( Bank 1 ) Sensor 1 ( upstream sensor ) and Sensor 2 ( downstream sensor ) On the drivers side ( Bank 2 ) Sensor 1 ( upstream sensor ) and Sensor 2 ( downstream sensor )
they have 2 o2 sensors on the muffler ELIA
I believe there are ( 4 ) Bank 1 is the passenger side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) Bank 2 is the driver side of the engine , sensor 1 is before the catalytic converter ( upstream ) and sensor 2 is after the catalytic converter ( downstream ) The 2 sensors before the catalytic converter are used for air / fuel ratio for the engine The 2 sensors after the catalytic converter are called catalyst monitors
They are the two wire sensors screwed into the front of the transmission case. The input is closer to the engine.
There are to many sensors to list. What sensor are you looking for, And what is the engine size. NEUTZ.
There is no egr. There are teo O2 sensors instead.
There are 4 O2 Sensors on the 1997 GMC Jimmy V6 4.3L. All sensors are accessed from bottom. All sensors are mounted on the exhaust. Three of the sensors are on the Bank 1 side of the engine (Passenger side). Sensor 1 Bank 1 is upstream of Y joint on Passenger Side, Sensor 1 Bank 2 is upstream of Y joint on drivers side. Sensor 2 Bank 1 is mounted down stream of Y before Cat Converter on Passenger side. Sensor 3 Bank 1 is downstream of Cat Converter on passenger side.
some are yes but the sensors have different connections
This is one of the two sensors which is downstream directly after the catalytic converter.
try www.autozone.com check on repair info and components location. Two. There is an upstream sensor before the catalytic converter, and a downstream sensor immediately after.
There are sensors inside the trans, outside the trans, and on the engine that will all affect shifting.
The engine computer is the voltage regulator in a 1997 Jeep Grand Cherokee.
upstream will be in the manifold, downstream refers to behind the converter Upstream o2sensor on exhaust manifold . from underneath have to reach up to where meets up with block. hard to reach . but not impossible
depending on the engine it will have two or three
There are 4 sensors, though not all of them are technically called "oxygen sensors. There are two that are upstream of the catalytic converters, one on each bank. Then, there are two more, one after each catalytic converter, that are oxygen sensors, but officially they are called catalyst monitors, because that is the job they are assigned to do. To recap, the two before the cats (or upstream), are oxygen sensors, and the two after the cats (or downstream) are catalyst moniters. Although all 4 of them are oxygen sensors, their titles are different.
need engine size. 2 or 4.
There are two screwed into the exhaust on the rear of the engine.
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter
There are a number of oxygen sensors on the 1997 Cadillac STS. These are found on the firewall, inside the exhaust manifold, and behind the catalytic converter depending on the engine model.
Sure, its the sameengine
