Maybe the sensors you changed out were not the problem. Post what the symptoms were, what the codes were, and why you changed out what sensors you did. Sometimes errantly the wrong part is diagnosed as being defective, like having low fuel pressure and people spend $500 for fuel injectors when in reality it was a clogged fuel filter for $10 Some cars take a few starting cycles or cycles of driving before they reset the check engine light. If you had someone read your codes, normally they have the ability to turn off the check engine light. If you replaced the incorrect part(s) then your check engine light will remin on until the part casuing the fault is replaced. I hope the parts you replaced were the problem and it's just a matter of havign the check engine light turned off. If not, repost and maybe we can direct you. Todays' engines are not like ones of old where you can throw parts at it and "feel" you got it fixed. It's either fixed right or the check engine light is there to remind you it isn't.
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 )
There are two.
There are two.
There are two.
Shoot a fire extinguisher or shoot the blinking control panel
Its located on your differential
The only "sensors" on the transmission are the speed sensor at the top in back, and the range switch on the front.
You're to late. They already have such sensors.
They are located in the door latch on the door
You will find all O2 sensors threaded into the exhaust system at various points.
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 )
Yes, all parts of a phone are solid (save for some intelligent phones' g-motion sensors which use liquid mercury as part of their sensors)
There is only the speed sensor and the range switch.
The oxygen sensors are in the exhaust pipes on most models.
Passenger ===================================================== Actually , bank 2 is the drivers side of the engine in a Mercury Mountaineer
O2 sensors are always located on the exhaust system.
it has a total of four
4 - 2 before the catalytic converter and 2 after
No, only one thermostat. It does have two temperature sensors though.
It depends what kind of sensor you mean. There are lots of sensors in trains already... for such things as heat/smoke detectors, doors (which stop the train moving unless the doors are closed, fuel, signal sensors..... etc
