Wrong scanner?? If a check engine light is on, there are codes.
Timing sensor? Check engine usually means a problem... Service means that scheduled service needs to be performed like oil change, or timing belt replacement.
I would Check your Catalytic Converter. What often happens is the catalyst that is in the Catalytic converter Heats up and Blows out into your Muffler.
This means It is not the sensor,but your converter and Muffler Need Replaced.I have just fixed two cars with this problem,and they had the same symptoms,Check engine Light.
And they are expensive to replace... (i replaced one @ $400)
The 2002 Pathfinder oxygen sensors are critical part of the engine management system. You can find the oxygen sensors in the exhaust system.
The 2000 Nissan Pathfinder has a total of four oxygen sensors - two before the catalytic converter, and two after the converter. The front sensors have 3-wires, and the rear sensors have 4-wires. For a good quality OE-style sensor, they'll cost around $100 each.

Reset it with an OBD2 scan tool. If it came on after replacing the sensors you may have another problem. Reset it and see if it comes back on.
They are replaced when they go bad.
4 oxygen sensors (2 front and 2 rear)
i had a problem with that on a dodge neon and i did the same things you did to fix the problem but it kept shutting down. Well to make a long story short it tuned out to be the computer( brainbox). replaced it and have not had a problem. This was common to the neon not sure on the durango but mabey something to look into
If you mean what is the purpose of the speed sensor on an auto transmission do, then the answer would be it replaces the speedometer cable. Basically it picks up how many revolutions the wheels are making and sends that to the ecu (the computer) and the computer computes how fast you are traveling. All speed sensors do the same job, just some for different purposes. Some cars have speed sensors on all wheels which is used for abs braking, while some (Like this pathfinder) have one used just to tell how fast you are going.
If the oxygen sensors for the 1991 Chevy 4.3 is running rich when it is warmed up it is best to have the sensors replaced. Once the sensors are replaced this should resolve the issue.
In a ball mouse, the ball, which is moved by contact on a surface, has three directional roll sensors which transfer electrical signals to the computer which then moves the mouse pointer on the screen. In laser and optical mice, the roll sensors are replaced by lasers or infrared sensors, which detect which direction the mouse is moving. This is sent to the computer which moves the mouse pointer. Laser and optical mice are more accurate than ball mice, but don't work on reflective or transparen surfaces such as foil or glass, which is not a problem for ball mice.
Have you had your 4 oxygen sensors replaced? It turns out when they replaced my oxygen sensors, they were after market parts so the service engine light did not come and gave codes even though they were replaced.
The computer does - there is no way to adjust it. If it is improper something is wrong with one of the sensors - that is the most likely problem.
The trans may not be the problem. Depending on the car the mechanical linkages or electrnic controlers (computer) or sensors could be bad A competent mechnic with the right scanner can watch all this work and see the issue.
ask your service station to do a compression test. I had the same problem and replaced all sensors and thermostat but after the test it was found out that there was a crack in the housing holding the thermostat
The o2 sensors are before the Cat. the are connected the a computer so unhook them, They can be replaced with the right open end wrench. Make sure that the car has been allowed enoug htime to cool. Tixo
I think it is all run off the computer. I would guess that some sensor or sensors are bad and need replaced because the sensors tell the computer how the gas and air mixture should be. I would take it and have a computer reading done on it to point you in the right direction as to which sensor/sensors may be acting up.
No, they will need replaced if defective.
The vehicles computer relies on the information from the 02 sensors and other sensors to adjust the engine for peak performance.
It could be a "slight" problem with the electronic sensors. If a "check engine" light is on, the computer has detected a problem with the sensors. You need to use a code scanner to detect the fault code.
have you had it serviced recently? your computer may be re-learning its idle pattern if any engine management sensors or devices have been replaced recently.
You will need to explain your problem. The transmission has it's own computer and sensors. Without knowing your situation it will be hard to diagnosis.
Wiring, computer, or engine mechanical problem.
It is important to know the location of all the sensors within a vehicle. The Oil sending unit in a 2000 Nissan Pathfinder is on the engine block, close to the oil pan.?æ
I had the same problem..... Throttle position sensor .... Mine was defective and was telling the computer that the gas peddle was down all the time....
