Question about 2005 Nissan Altima

1 Answer

My service engine soon light stays on, I figured out that it's a Oxygen sensor. In the past colder months the light would come on for a couple days, then go off for a period of time. I am thinking the reason for that activity is because colder air is more oxygen rich. Now my question is.. where can I find that O-2 sensor, can I change it myself, and is it expensive?

It should be close to the muffler. You can change it however the engine must be warmed up in order to remove the sensor. If you change it make sure you use anti seeing commpound when you replace the sensor. Prices vary from $15.00 to $100.00. Check with auto store for price. Might get a better deal on Ebay.

Toyota Vitz 2007, 1.0 L, check engine light comes on at 100 km/h and goes off after turning off engine but comes back again at high acceleration like 100 km/h. change oxygen sensor as well.


That code is actually due to the fuel pressure being too low and causing a lean condition that the oxygen sensor picks up. It is common in that vehicle. Check the fuel pump pressure, filters etc.

1996 dodge caravan 2.4 liter 4 cylinders .Engine service light comes on for a period of 2 to 3 months then goes off .Prior to this the engine light stayed on continuously ,until the oxygen sensor connected...


There is some sort of diagnostic code stored in either the ECM(engine computer) or TCM(transmission computer).There are many sensors and solenoids and other data parameters that can cause a codes to set other than just the oxygen sensors.You will need to have the code(s) pulled to know where to start.

Where is oxygen sensor located because service eng. soon light stays on


There are two O2 sensors. One in the Y pipe where it connects to the exhaust pipe and the second one is in the exhaust pipe between the catalytic converter and the muffler. There a hundred things that will cause the service engine soon light to come on. A problem with the O2 sensor is just one of them.

Airbag light and service soon light


You need to take this to a shop and have the airbag system repaired as that light is indicating a fault in the airbag deployment system. The service Engine soon light could be nothing more that a reminder to change the oil but is most likely an Oxygen sensor that needs replaced.

Change oil soon light stays on and service engine soon light has come on.


You reset the change oil soon light by a couple of different ways depending on your model. Your owners manual will let you know. Some is by depressing the accelerator when car is not running but in accessories mode on ignition. Others you can reset through the radio. Take a look at your owners manual on this. For the service engine soon light, take it to a autozone and they will run a diagnostic for free. Then they can tell you just what is going on and will have the part to fix it. It is probably an oxygen sensor if it is otherwise running fine. good luck and I hope this helps.

2001 Nissan Maxima service engine light stays on code from Auto Zone scanner is PO139 and PO138. What should my next step be to solve this problem.


code p 0138 refers to 2 items
1--heated oxygen sensor(HO2S) 2 bank 1--high voltage ==causes --wiring short to positive --HO2S---ECM
2--oxygen sensor (O2S) 2 bank 1--high voltage ===causes wiring short to positive ---ECM
code p 0139 refers to 2 items
1--- heated oxygen sensor (HO2S) 2 bank 1--slow response ===causes --heating inoperative --wiring--ECM
2--oxygen sensor (o2S) 2 bank 1 slow response ===causes --wiring --- O2S

heated oxygen sensors9HO2S) are in the exhaust manifold before the cat converter
Oxygen sensors (O2S) are after the cat converter
it is indicated that the HO2S is faulty-
check the wiring and /or replace both sensors

2003 Buick Regal Service Engine Soon light.


The error that I'm showing for error code P1133 is 
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank).  I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done.  Hope this helps.  Thanks for an honest rating and for using FixYa.
