2011 Honda Elysion MAP sensor — purpose and easy service tips

Yes, the 2011 Honda Elysion uses a MAP (Manifold Absolute Pressure) sensor. This is documented in Honda’s factory service manual for the Elysion (RR1–RR6, 2004–2012, Engine Control System) and the Honda Electronic Parts Catalogue, which list a MAP sensor for both the 2.4-litre K24A and the J‑series V6 variants. The presence of OBD‑II diagnostics for MAP-related faults (such as P0106–P0108) in Honda literature further confirms it’s part of the engine management on this model.

On the Elysion, the MAP sensor measures the vacuum/pressure inside the intake manifold. The ECU uses that reading, along with intake air temperature and throttle angle, to work out engine load. That informs fuel delivery and ignition timing, helping the van start crisply, idle smoothly and pull well without guzzling petrol. Unlike a MAF-only setup, Honda’s strategy here leans on the MAP signal for reliable “speed‑density” calculations.

It’s typically mounted directly on the intake manifold: on the K24A near the throttle body on top of the manifold, and on the V6 on the manifold toward the firewall side. It uses a 3‑wire connector (5 V reference, signal, earth) and seals with a small O‑ring.

• Common symptoms of a dodgy MAP: rough idle, flat spots on take‑off, higher fuel use, hard starts, and a check engine light with MAP codes (P0106–P0108).
• Quick visual checks: cracked connector locks, oil mist contamination, perished O‑ring, or vacuum leaks at the manifold.

Servicing is straightforward. While the MAP sensor isn’t a regular “replace at X km” item, it’s worth a look every 40,000–60,000 km or when chasing drivability gremlins. If there’s oily residue, remove the sensor and gently clean the tip with electronics-safe contact cleaner—don’t poke the sensing diaphragm and let it dry fully. If cleaning doesn’t settle the trims or clears the codes only briefly, replacement is the go.

1. Disconnect the battery (ignition off) and unplug the 3‑pin connector.
2. Undo the retaining bolt/screw, lift the sensor straight out, and inspect/replace the O‑ring.
3. Install the new unit, seat it squarely, tighten to light hand tension (it’s a small fastener), reconnect, and clear codes.

Stick with a quality OEM‑spec MAP sensor and avoid silicone sealants on the O‑ring seat. After replacement, a short relearn drive—mixed urban and a few steady kilometres at cruise—helps the ECU settle trims. If MAP codes persist, smoke‑test the intake for leaks and confirm 5 V reference, ground integrity, and signal voltage with a multimeter as per the Honda service procedure.

Does the 2011 Honda Elysion have both a MAP and a MAF sensor?

The Elysion’s engine management relies on the MAP sensor for primary load calculation. Some variants may also have an intake air flow or temperature sensor in the intake tract, but the MAP is the key player for fueling and timing on this platform. Always check the specific engine code and parts catalogue for your VIN.

Where exactly is the MAP sensor on my Elysion?

On the 2.4 K24A it’s usually on the top side of the intake manifold near the throttle body. On the V6 it’s mounted on the manifold toward the rear (firewall side). Look for a compact sensor with a 3‑pin plug and a single retaining screw or bolt.

Can a dirty MAP sensor cause poor fuel economy?

Absolutely. A contaminated or lazy MAP skews the ECU’s load reading, which can richen mixtures and bump up fuel use. If cleaning doesn’t stabilise readings and trims, replacement is recommended.
