2007 Nissan Maxima MAP Sensor — What’s actually on the car

According to the Nissan 2007 Maxima Factory Service Manual (EC section) and the Nissan FAST parts catalogue for the A34 VQ35DE, this model is a mass‑airflow (MAF) based system and does not use a separate manifold absolute pressure (MAP) sensor. Technical repair databases commonly used in workshops, such as AllData and Mitchell1, also list no stand‑alone MAP sensor or MAP service procedure for this vehicle. Some aftermarket listings use “MAP” as a catch‑all term, but for this Maxima there’s no MAP screwed into the intake manifold to replace.

Why no MAP on a 2007 Maxima? Nissan engineers built the VQ35DE management around a hot‑wire MAF sensor in the intake duct. The engine control module calculates load primarily from MAF readings, engine speed and throttle position, then trims with the oxygen sensors. Barometric pressure is handled internally by the ECM, so a dedicated manifold pressure sensor isn’t required on this naturally aspirated setup.

What should owners focus on instead of a MAP? If the car feels doughy off the line, idles rough, or shows poor fuel economy, the usual culprits are a dirty or failing MAF, unmetered air from vacuum leaks, a grubby throttle body, or aged PCV hoses and intake gaskets. Chasing a MAP that isn’t there wastes time and coin.

• MAF care: Clean the MAF with a proper MAF‑safe cleaner every 40–60,000 km, especially if a high‑dust environment or oiled filters have been used under the bonnet.
• Air leaks: Inspect the intake tube, airbox seals, and vacuum hoses, a smoke test is gold for finding sneaky leaks.
• Throttle and PCV: Periodically clean the throttle body and check the PCV valve and hoses for cracks and collapse.
• Codes to watch: P0101/P0102 (MAF performance), lean codes P0171/P0174, and rough idle after battery disconnect often point to MAF/throttle relearn or air leaks, not a MAP issue.

Bottom line for this model: there’s no MAP sensor to service or replace. Keeping the MAF clean, the intake airtight, and the throttle body tidy will keep the VQ35DE running sweet and save headaches at service time.

Popular questions about the 2007 Nissan Maxima “MAP sensor”

Does a 2007 Nissan Maxima have a MAP sensor?
It doesn’t. The VQ35DE uses a MAF sensor for airflow measurement and the ECM handles barometric pressure internally. There’s no separate MAP bolted to the manifold on this model.

Where is the MAP sensor located on a 2007 Maxima?
There isn’t one to locate. Under the bonnet you’ll find the MAF in the intake duct near the airbox. If someone points to a “pressure sensor”, they’re likely mixing it up with EVAP system components or vacuum switching valves, which aren’t manifold pressure sensors.

What should be serviced if the car shows “MAP sensor” symptoms?
Focus on the MAF (clean or replace if faulty), check for vacuum and intake leaks, clean the throttle body, and inspect PCV hoses. These steps address the issues owners often attribute to a non‑existent MAP sensor.
