2012 Honda Elysion MAP sensor — what it does and how to look after it

Technical sources confirm the 2012 Honda Elysion is fitted with a Manifold Absolute Pressure (MAP) sensor. The 2012 Honda Elysion Electrical Troubleshooting Manual (RR1–RR6) lists the MAP sensor as a primary PGM‑FI input and details DTCs P0106–P0108 for MAP performance and voltage faults. Honda’s K24A and J35A/J35Z PGM‑FI service manuals specify a three‑pin MAP sensor mounted on the intake manifold, and the closely related 2008–2013 Honda Odyssey RB3/RB4 workshop manual shows the same intake‑mounted MAP arrangement. On that basis, a MAP sensor is relevant and used on the 2012 Elysion.

On this model, the MAP sensor reads the pressure (vacuum) inside the intake manifold so the ECU can figure out engine load. That data drives fuelling, ignition timing, EGR flow checks and idle control, keeping the big Honda smooth and efficient from school runs to long motorway slogs. Whether it’s the 2.4‑litre K‑series or the V6 J‑series, the MAP is a core player in accurate mixture control.

While the MAP sensor isn’t a regular replacement item, it does appreciate a little attention. Oil mist and EGR soot can film over the sensing port, skewing readings. As part of routine servicing, it’s smart for an Elysion owner to visually inspect the sensor and its O‑ring, check the 3‑pin connector for corrosion, and make sure the vacuum port isn’t blocked.

• Common hints it’s unhappy: rough idle, sluggish throttle, higher fuel use, hard starting, and a MIL with codes like P0106, P0107 or P0108.
• Quick care: if lightly fouled, a short burst of electronics‑safe sensor cleaner on the port can help. Avoid poking tools into the opening.

Replacement is straightforward driveway work. With the engine off and cool under the bonnet, unplug the connector, undo the retaining screws, lift out the sensor and O‑ring, then seat the new sensor squarely. Refit the screws snug to factory spec and reconnect the plug. Use a quality OEM‑equivalent part that matches the engine code. After any replacement or a battery disconnect, clear codes with a scan tool and perform an idle learn so the ECU settles quickly.

There’s no fixed kilometre interval for changing the MAP on a 2012 Elysion. As a rule of thumb, inspect it every 40,000–60,000 km or whenever chasing fuel economy or drivability niggles. Keeping the air filter fresh and vacuum hoses tight also helps the sensor read clean, accurate manifold pressure.

Where is the MAP sensor on a 2012 Honda Elysion?

It’s mounted on the intake manifold with a three‑pin connector. On the K24A four‑cylinder, it sits near the throttle body at the front of the bay. On the J‑series V6, look between the cylinder banks near the throttle body area. It’s small, rectangular, and secured by a couple of screws.

What fault codes point to a MAP sensor issue on this model?

Typical codes are P0106 (MAP range/performance), P0107 (low input) and P0108 (high input). Sometimes mixture or idle control codes appear as well. Keep in mind, vacuum leaks or a blocked MAP port can trigger the same faults, so testing the circuit and checking hoses is worth doing before replacing parts.

How often should the MAP sensor be serviced or replaced?

There isn’t a set replacement interval. A quick inspection every 40,000–60,000 km works well, with a light clean if there’s oil or soot build‑up. Replacement is recommended only if it fails testing, shows physical damage, or the ECU data and diagnostics confirm it’s out of spec.
