Hey Guys,


I’m new here and I got a Nissan Maxima 2005 3.5 SL with 196,000 miles. I got many error codes after visiting Auto Zone can anyone guide me where to start? I was recommended to start with O2 sensor but I have already changed that 5 months ago. I did loan out my car to my sister for 2-3 months got it back in this condition. Some already existed and I been working off slowly but I’m new dealing with cars. Hence I’m here at a forum lol. Please advise:

Codes:

P1031
P1148 Generator 2 Control Circuit
P1168 Fuel Raul Pressure Sensor In Range But Los
P0037 HO2S Hester Control Circuit Los (Bank 1, Sensor 2)
P0057 HO2S Hester Control Circuit Los (Bank 2, Sensor 2)
P1051 - No description given
P1031 - No description given
P0021 Intake Camshaft Position Timing - Over Advance (Bank 2)
P2135 Throttle/Pedal Position Sensor/Switch A / B Voltage Correlation

My head is spinning lol please help?

I also have a straight pipe. No converter could this be the issue? I have changed the O2 sensor couple of months ago. A mechanic at AutoZone suggested I start there with the O2 sensor.

 

Thoroughly heck the grounding points, battery and alternator first.
If you have an aftermarket alarm, try to turn it off for the time being.

 

I do have electrical issues. Would that be a contribution then?... seems like so from your suggestion...

 

Definitely. Make sure that the quality of electric supply to the ECU is "like new". Both +12V and ground contribute to that. Only once you ensured that your alternator is working fine and the battery is is doing its job, it would make sense to tackle the rest of issues.

 

Removed, wrong post.
