2014 Nissan Serena MAP sensor: what it is, where it fits, and how to look after it

Technical verdict: the 2014 Nissan Serena (C26 series, incl. S-HYBRID with the MR20DD engine) is fitted with a manifold absolute pressure (MAP) sensor. Factory documentation such as the Nissan Serena C26 Electronic Service Manual – Engine Control (EC) section lists the “Intake Manifold Pressure Sensor” and related DTCs P0106/P0107/P0108. The Nissan FAST parts catalogue identifies a “Sensor Assy – Pressure (Manifold)” for C26 models, and major OE suppliers (e.g., Hitachi Automotive Systems and DENSO) catalogue direct MAP replacements for this vehicle. These technical sources confirm the MAP sensor is relevant and used on the 2014 Serena.

On this model, the MAP sensor works alongside the MAF to help the ECM pin down engine load with better accuracy. It reads the absolute pressure inside the intake manifold and, together with intake air temperature and MAF data, helps the Serena deliver tidy fuel economy, smooth idle-stop restarts on S-HYBRID variants, and reliable altitude compensation across Aussie and Kiwi conditions.

There’s no scheduled replacement interval for the MAP sensor, it’s a solid-state unit designed to last. That said, servicing the Serena is a good time to give it a quick once-over. Under the bonnet, the MAP sensor sits on or near the intake manifold close to the throttle body. Check the connector for corrosion or loose pins, make sure the wiring loom isn’t rubbing through, and confirm the O-ring is sealing properly. Avoid drowning the sensor tip in solvent, if there’s light contamination at the port, a careful wipe and a gentle blast of electronics-safe cleaner on the plug is the go.

Symptoms of a crook MAP include rough idle, flat spots, sluggish take-off, increased fuel use, hard starts, or the MIL on with codes like P0106–P0108. If replacement’s needed, stick with quality OE-equivalent parts. Swapping it is usually straightforward: ignition off, disconnect the plug, remove the retaining fastener, lift out the sensor, renew the O-ring, and refit. After installation, clearing fault codes with a scan tool is wise, the ECM will adapt quickly during a short drive cycle. If drivability still isn’t right, look for vacuum leaks, a sticky throttle body, or EGR issues that can skew manifold pressure readings.

• Common signs it needs attention: rough idle, poor economy, hesitation, MIL with P0106–P0108.
• Service tip: inspect connector and O-ring at each major service, avoid spraying the sensing element.
• Fitting tip: reseat the harness firmly and verify no vacuum leaks after refit.

Popular questions about the 2014 Nissan Serena MAP sensor

Where is the MAP sensor on a 2014 Serena?
It’s mounted on the intake manifold near the throttle body under the engine cover. Look for a small, one-bolt sensor with a 3‑pin plug. On S-HYBRID variants with the MR20DD, it’s still in the same area, reading manifold pressure directly.

Can the MAP sensor be cleaned, or should it be replaced?
Light external cleaning of the port and the connector is fine, but don’t soak the sensing element. If it’s oil-soaked internally, cracked, or triggering repeat DTCs (P0106–P0108) after checks for vacuum leaks and wiring issues, replacement is the better move.

What MAP readings are normal at idle?
At sea level, a healthy naturally aspirated MR20DD typically shows roughly 25–40 kPa absolute at warm idle (varies with altitude and engine condition). Under load, readings climb towards ambient (around 100 kPa at sea level). Always interpret readings alongside MAF, RPM, and fuel trims.
