2013 Honda Elysion MAP sensor — what it does and how to look after it

Yes, the 2013 Honda Elysion uses a MAP (Manifold Absolute Pressure) sensor. This is supported by Honda factory service information for the K‑series 2.4‑litre and J‑series V6 engines fitted to the Elysion (RR1–RR6), which include diagnostic and replacement procedures for the MAP sensor, and by Honda’s electronic parts catalogues listing a manifold pressure sensor and O‑ring for these models. Technical training material from Honda on “speed‑density” fuelling also notes the ECU’s reliance on the MAP sensor as a primary load input on K‑ and J‑series engines.

On the 2013 Elysion, the MAP sensor sits on the intake manifold near the throttle body. Its job is to report manifold pressure to the ECU so the engine can calculate air mass, trim fuel, set ignition timing, and manage idle and EGR. Because the Elysion’s system is speed‑density rather than purely MAF‑based, a healthy MAP signal is crucial for smooth take‑offs, good fuel economy, and clean emissions.

When the MAP sensor drifts or fails, owners may notice rough idle, flat spots, higher fuel use, hard starts, or the check engine light with codes like P0106, P0107, or P0108. Left unchecked, the ECU will run on default values that can wash fuel into the cylinders and foul the cat — not ideal for the wallet or the environment.

There’s no fixed replacement interval. As part of regular servicing, a quick visual once‑over under the bonnet goes a long way: make sure the MAP’s 3‑pin connector is snug, the vacuum port isn’t gunked up with oil mist, and the O‑ring isn’t perished. If readings are erratic on a scan tool or codes return, replacement is the smart move.

• Inspection: with the engine off, unplug the connector, check for green corrosion, oil in the plug, or cracked wiring. Inspect nearby vacuum hoses for splits.
• Cleaning: if there’s light residue at the port, use electronics‑safe cleaner on a cloth around the opening. Don’t poke the sensing element or flood it with solvent.
• Replacement: remove the retaining screw(s), lift the sensor straight out, swap the O‑ring, and seat the new unit squarely. Key off during the swap. Clear codes and perform a basic idle learn (warm up, then let it idle a few minutes with all accessories off).

Done right, a MAP sensor job on the Elysion is a tidy, driveway‑level task that restores crisp throttle response and keeps the ECU happy — no dramas.

Popular questions

Where is the MAP sensor on a 2013 Honda Elysion?
It’s bolted to the intake manifold close to the throttle body, with a small 3‑pin electrical connector. On the 2.4‑litre it’s typically on the upper manifold where it’s easy to see, on the V6 it’s mounted on the plenum in a similarly accessible spot under the engine cover.

Can a faulty MAP sensor be cleaned, or does it need replacing?
Light contamination at the port can often be tidied up with electronics‑safe cleaner, but internal sensor faults won’t recover. If scan data stays jumpy, codes return, or drivability doesn’t improve, replacement is the fix.

What symptoms point to a bad MAP sensor on an Elysion?
Common signs include rough idle, sluggish acceleration, higher fuel consumption, hard starting, and the check engine light. Fault codes P0106, P0107, or P0108 are strong clues the MAP signal is out of range.
