I have an 03 Maxima, and have gotten Error Codes P1574 and P0720. Research says to replace these sensors, but I am unsure of the actual part numbers to purchase. Can anyone help with the part #s of both the sensors pictured below? Thanks!

Here's some pix w/ part number

 

Thank you. Are both sensors the same part number? While I have things apart figure I might as well replace both. I did clear the code and hasn't popped back up for some time.

 

so I went to start my car and the AT CHECK light came on. However the Service Engine Soon light did not come back on. Is there someone that can assist with the part numbers to replace the sensors? I am going to guess that's the underlying issue. Has anyone else ran into this problem?

 

Those sensors are the same part. Nissan calls it "Sensor Assy-Revolution", part number 31935-8E006. The Nissan MSRP is $161.27. You can get them on-line for around $120 - $125 plus shipping.

If you want non-nissan, here is a link to rockauto.com. They have 3 brands between $70 and $90 (plus shipping), but you can get 5% off if you enter code MMJJ811 in the "how did you hear about us" box if you order by 8/31/15.

My car just threw the same codes (P1574 & P0720). I ran under something and the plastic mud shield broke the plug off the sensor that is labeled "Upper Outer Sensor". I changed the sensor and the codes did not reappear. I would change that one first and see if they come back.

 

From everything I'm seeing from mechanics on YouTube, it's the outer sensor that acts up and causes the P0720 code. I'm trying that on mine I will follow up with my results. I've already replaced the transmission once before with another used one, I hope this works this time.

 

(Faaaded) Midnight Blue 💙 2007 SE Bought in 2010 still whipping it to work down the 405 fwy (LAX) . Clean and always maintained minus the paint of course. I'm 40 YR OLD that carry 2 child seats so the new Nissan Z is out the window. I was also looking into the Maxima 2020 40th anniversary ed. Then I thought about how I never gave my 07 Maxima a chance to flourish beyond an aftermarket grill. So now... In 2023, on my new Longshoremans salary, I've decided that I want to build up the maxima while I drive my truck for a bit. What brought me to this thread were questions I was asking myself about CORRELATION BETWEEN cold air intake and header/exhaust systems. But before I go any further. Is there a header swap system between the 07altima and 07 Maxima identical to what is stated in this post as far as compatibility? Anyone still here? Lol 😂
