Might have to lower exhaust pipe, depending on which O2 sensor you are replacing, upstream or downstream. There are sensor sockets available or a metric wrench. Also available is a crow foot wrench that can be used with a ratchet.

Where is the oxygen sensor located for nissan sentra lec


this is from the web, yahoo answers I think




Best Answer: That was the dumbest answer. On a four cylinder engine a o2 sensor is reading the air fuel ratio from the exhaust of all four cylinders. There is a o2 sensor before and after the catalytic converter. Bank 2 is refering to the o2 sensor after the cat. When u replace it you need to inspect the cat and make sure its not coming apart from the inside. If it is you need a new one. If u cant afford one then i would just hollow out the cat with a large screwdriver. If u hollow it out ur car wont pass emission testing.

My car keeps dying when temp.gos up


your front oxygen sensor/lambda sensor is broken. you need to replace it. it stalls because o2 sensors start to work at higher temperatures(when cold car uses previous know error free mixture ratio - rich mixture). when engine is warmed up, your o2 sensor cant read correct values and engine controller cant decide on required amount of fuel to be burned in chamber.

Already replaced o2 sensor 2 times which means im getting ready to install 4th o2 sensor and cant figure out whats causing o2 sensor to fail. car is idleing rough but not stallin yet. please help


What is your Trouble code? O2 sensors just don't go bad, unless you are buying cheap parts. Need to find out why its idling rough. if there are no codes have a repair shop review the scan data and see why its running rough.

I need a diagram showing the location of the o2 sensors on a 2001 chevrolet impala


Why would you need a diagram?

You simply need to educate yourself

O2 Sensors have been on vehicles over 25 years,and in the same place

Sensor 1--in exhaust pipe before converter or in converter
Sensor 2 in outlet of converter

An O2 Sensor Code---Does Not mean replace it

New o2 sensor went bad in 1 day after being


The connections to the sensor is heater voltage which is +12 volts supplied by external (from the ECM) wiring from the battery, and the 0 to + 5 volt self-generated signal from the O2 sensor is an input to the ECM. Suggest that you find another mechanic that isn't intent on selling parts. Also suspect is the quality of the replacement O2 sensor. It would take a major disaster within the ECM to make an input connection turn into an output and would likely damage the O2 sensor almost immediately--not a day later. Hope this helps!

I have a code po141 what i have to do what piece a have to change in where are this pieces


Code PO141 indicates that the heater circuit in the Oxygen Sensor mounted in Bank 1 (Driver's Side) is not working properly. The ECM has determined that the sensor is taking too long to heat up to around 600 degrees and then switch out of close loop mode. If the ECM determines that it is taking too long then a code PO141 will be set. Normally it is the sensor itself that is defective. Replacing the sensor normally will fix the problem. However it can be the wiring harness or a a bad connection. Check the wiring carefully and look for a short in the wiring. If you find none then replace the O2 Sensor. If this does not repair the problem do not replace any other parts. Time to take it to a professional with professional tools and diagnostic skills to find the problem. The O2 sensor is more than likely the problem but there is no guarantee that will fix it.

How do i install a o2 sensor myself?


The sensors that you purchased were probably universal. These are normally much cheaper than OEM replacement parts. They should have came with wiring instructions and extra parts, you will have to re-wire the harness. If you were not given the parts to change the plug then you may have been given the wrong sensors. You should call the Auto Parts store and double check the Part number to ensure that it is right. Also it could be that the vehicle does not have heated O2 sensors, if this is the case than you need to get O2 sensors that are not heated to replace them.
