Parts for your 2007 Nissan Primera-Maf sensor

2007 Nissan Primera MAF sensor — what it does and how to look after it

Technical sources confirm the 2007 Nissan Primera (P12) is fitted with a hot-film Mass Air Flow (MAF) sensor. Nissan’s P12 Service Manual (Engine Control “EC” section) shows a “Mass Air Flow Sensor (with Intake Air Temperature)” in the intake duct. Nissan’s FAST electronic parts catalogue lists applicable MAF assemblies for the P12 with QG18DE, QR20DE petrol and YD22DDTi diesel engines, and major aftermarket catalogues (Hitachi, Bosch) carry direct-fit replacements under Nissan part families such as 22680-7S000 and 22680-AW400.

On the 2007 Primera, the MAF sits just after the air filter under the bonnet and measures how much air is being drawn into the engine. The ECU uses that live airflow data (plus the built-in intake air temperature reading) to nail the fuel delivery and ignition timing. That’s how it keeps the car smooth off the line, frugal on the motorway, and clean at the tailpipe. Petrol or diesel, a healthy MAF is central to good driveability and economy.

While the MAF isn’t a routine “replace on schedule” item, it absolutely benefits from preventative care. Dusty roads, oiled filters, or a tired air filter can coat the sensing film and throw out the readings.

• Symptoms of a crook MAF: rough idle, flat spots, sluggish acceleration, higher fuel use, check engine light (common codes P0100–P0104), smoky exhaust on diesels, or hunting at idle.
• Service tip: replace the engine air filter on time to protect the sensor. Avoid oiled filters that can contaminate the hot film.
• Cleaning: if readings are suspect but the sensor isn’t dead, use a dedicated MAF cleaner only — never carb/throttle cleaner. Remove the unit carefully, spray the element, let it air-dry, and refit. Don’t touch the sensing wire.
• Replacement: if cleaning doesn’t help or the circuit has failed, fit a quality unit matched to the exact engine code. Cheap knock-offs can cause more grief than they solve.
• After refit: ensure there are no intake air leaks, clear fault codes, and perform an idle/air volume learn if needed (Nissan specifies this after certain ECU or airflow component changes).

Looked after properly, the Primera’s MAF keeps the 1.8, 2.0, or 2.2 dCi running sweet as, with crisp throttle response and tidy fuel figures across Aussie and Kiwi conditions.

FAQs

Where is the MAF sensor on a 2007 Nissan Primera?

It’s mounted in the intake duct just downstream of the air filter box. Look for the small electronic module with a multi-pin plug between the air box and the intake hose. On right-hand-drive P12 models it’s typically near the front-left of the bay under the bonnet.

Can a dirty MAF be cleaned, or does it need replacing?

If the sensor is merely contaminated, a proper MAF cleaner can restore accurate readings. If there’s internal circuit failure or persistent fault codes after cleaning and leak checks, replacement is the go. Always use a correct-spec part for the specific engine.

What causes MAF sensors to fail on the Primera?

Common causes include dust ingress from overdue air filters, oil vapour contamination from oiled filters, intake leaks introducing unmetered air, and age-related electronic failure. Keeping the intake sealed and the filter fresh drastically extends MAF life.
