So I have 2009 Nissian Maxima, and for the second time my car has lost power and shut off. The VDC off and tire traction light comes on and boom its cuts on in mid traffic. I have replace the camshaft sensor & O2 Sensor. I read others and they said check the brake fluid and that is full to the max! What else could it be?? It runs fine all day and then boom the next day cuts off and I have to get towed or wait hours to finally drive. Help!!!

 

We could really use any diagnostic codes. What led you to replace those parts?

 

I took it to Autozone and they told me it was those sensors. Today A New code just came up p1148

 

 

Well, if your air-fuel ratio sensor is not working at all, which results in the code P1148, then that is a major issue leading to you not being able to drive the car.

Have a read - https://www.troublecodes.net/p1codes/p1148/

 

TD is on.point. i would suspect the new O2 sensor. Either the wrong type or installed on the wrong location. Either way, bad things will happen if A/F isnt correct. It may also be a clogged cat. But start with the O2 swnsor, where did you install it, what brand and PN?

 

Thanks for replying back! I replaced the front O2 sensor and I purchased it at my local autozone.

 

Was it a Denso brand O2 sensor? These cars like OEM #1 Denso #2 and nothing else.

 

yes It was a Denso Brand? So should I take it off and get the OEM brand?

 

I would also check the location. You stated you replaced the front one, but a p0301 is for bank 1, which is by the firewall if I remember correctly.

 

ok the code I got previously was P0031 for bank one.. So I should get P0301 instead? I also was advised to get the p1148 sensor too, for the close loop error code I got.

 

Sorry, i meant p0031. Bank 1 is by the firewall too. I would check my part numbers and locations.

 

Also, wanted to add, there are 2 different part numbers for these sensors (4 if you consider the ones after the cats)
The OEM part number you want for the Bank1 (p0031) is 226931AA0B and is probably responsible for your p1148 as well. Get that replaced and then lets check codes and see if your car does any better.

Your scan tool indicates 5 errors but you only shared 3. What were the other codes?

 

OK, I order the Sensors they should be in this Tuesday. The codes I showed was the only ones that agent told me to take a picture of so he could check to see what the codes meant. I order a sensor for the p1148 which costed $179. should I hold off on that one and just get the P0031 Sensor for heater Bank 1

 

The 1148 is saying it cant talk to the O2 sensor causing the P0031. This is usually disconnected wire, bad sensor or WRONG O2 sensor. I dont know what other sensor you are referring to.

 

oh okay.. The other sensors the agent told me to get was the AFR sensor, thats the high price one.

 

I just took it to the Shop and they told me to replace the ECM for $1400. Said the codes change everytime they check them. Is the a reasonable price for what he has to fix?

 

I suggest you find a new mechanic. ECM's don't go bad on this car. He's clueless.

 

i would get a second opinion. While 1400 for an ecm isnt bad, i highly doubt that is your issue.

 

You need to be looking at the Engine Coolant Temperature Sensor....

 

Ok, I will check that when I go to get my car back.

 

They were my second opinion. Took it to Tripple A and they told me the didn’t know what it could be and to replace my Gear shift assembly. Something about the pin and how it doesn’t go into park or drive but that was a lie and they wanted $1100 to do that. But that wasn’t a problem. It only cuts off and the VDC off and Traction Light Comes On. It reduce speed and sooner or later cuts off. I hate that these shops isn’t truthful and honest about my car and it makes it no better than I am a female with no knowledge about cars

 

The cam sensors are what's killing it while you're driving.

 

Ok I already replaced the 1 camshaft sensor, but it was that denso brand, Im see if I can get the other brand that was mentioned before.. The heater bank 1 sensor came in today I can see if they will put it in and see it that works.. Do you know how many camshaft sensors there are?

 

How long have you had this car? Did you just get it and these issues popped up?

 

Yes, I just got it in July and a month ago it started with this issue

 

Four cam sensors and they're all the same part #. Stick with OEM for sensors. Nissanpartsdeal.com. Get a copy of the FSM and ID the sensors (bank 1 bank 2 "A" "B" etc)
