Parts for your 2017 Nissan Serena-Map sensor

2017 Nissan Serena MAP sensor — what it does and how to look after it

Based on Nissan’s technical references for the C27 Serena (Electronic Service Manual, EC—Engine Control) and the Nissan FAST parts catalogue for C27 models, the 2017 Nissan Serena is fitted with a manifold absolute pressure (MAP) sensor. This applies to both the MR20DD S-HYBRID petrol variant and the e-POWER variant. Industry data services used by workshops (e.g., Autodata/ALLDATA) also list MAP-related diagnostics (DTCs P0105–P0108) for 2017 Serena drivetrains, reinforcing that the sensor is part of the engine management on these vehicles.

On the 2017 Serena, the MAP sensor reads the pressure inside the intake manifold. The engine control module uses that pressure signal, together with engine speed and temperature inputs, to work out engine load. That load calculation helps fine-tune fuel delivery, ignition timing, EGR operation and, on hybrid variants, when and how the petrol engine should contribute. The result is smooth drivability, decent fuel economy and lower emissions whether the family’s cruising the motorway or inching through city traffic.

The MAP sensor isn’t a scheduled replacement item, but it’s smart to give it some attention during servicing:

• Tell-tale signs it’s unhappy: rough idle, flat spots on take-off, higher fuel use, black tailpipe smoke, hard starts, or a check engine light with MAP-related codes.
• Where it lives: typically on or near the intake manifold, close to the throttle body. It’s a small sensor with a vacuum port and a 3‑pin electrical connector.
• Inspection and cleaning: during routine services (say every 40,000–60,000 kilometres), check the sensor and its vacuum port for oil mist or carbon from PCV/EGR. If dirty, remove it and gently clean the port with electronics-safe cleaner. Don’t poke the sensing element with tools.
• Vacuum integrity: perished O‑rings or a cracked manifold hose can skew readings. Replace any hardened seals and make sure the sensor seats firmly.
• Replacement tips: disconnect the battery negative, unplug the connector, remove the fixing screw(s), swap the O‑ring, fit the new sensor, and reconnect. Afterward, clear codes and perform an idle/ECM relearn if applicable. A quick test drive under the bonnet closed confirms all’s well.

For e-POWER cars, even though the petrol engine mainly acts as a generator, the MAP sensor still matters. It helps the ECU choose efficient operating points and keep emissions tidy when the engine spins up under the bonnet. Keeping that tiny sensor clean and sealed makes a big difference to how the Serena feels day to day.

Where is the MAP sensor on a 2017 Nissan Serena?
It’s mounted on the intake manifold, usually near the throttle body, with a small vacuum port and a three‑wire plug. On e-POWER models the packaging is a bit tighter, but it’s still on the manifold area and accessed once engine covers are off.

Can the car be driven with a faulty MAP sensor?
Usually, yes—but it’s not ideal. The ECU may fall back to a default strategy, which can mean sluggish response, poor economy and higher emissions. Best to diagnose and sort it promptly to avoid fouled plugs or a blocked catalyst down the track.

Does the Serena use both MAF and MAP sensors?
Many MR20DD S‑HYBRID cars run both a mass air flow (MAF) sensor and a MAP sensor. The e‑POWER setup leans more on manifold pressure for load calculation. Variations exist by market, so checking by VIN or looking under the bonnet is the safest bet.
