2019 Honda Odyssey MAP sensor — what it does and how to look after it

Yes, the 2019 Honda Odyssey is fitted with a Manifold Absolute Pressure (MAP) sensor. Honda’s factory service information for the 2018–2020 Odyssey (J35Y6 3.5‑litre V6) lists a MAP sensor in the Fuel and Emissions section, and the Honda parts catalog for the 2019 Odyssey includes a “Sensor Assy., MAP.” Honda diagnostics also document MAP-related DTCs (P0106, P0107, P0108) for this model. Those technical sources confirm the MAP sensor is present and very much part of the engine management strategy.

The MAP sensor measures pressure inside the intake manifold and helps the engine computer calculate air mass, fuel delivery, and ignition timing. On the Odyssey, it also feeds load data that influences features like Variable Cylinder Management. Under the bonnet, it’s typically mounted on or near the intake manifold close to the throttle body.

When the MAP sensor plays up, the Odyssey can feel a bit doughy off the line, idle roughly, drink more fuel than usual, or flash the Check Engine light. Common fault codes include P0106 (range/performance), P0107 (low input), and P0108 (high input). Vacuum leaks or a loose intake hose can mimic MAP issues too, so it’s smart to rule those out.

There’s no scheduled replacement for the MAP sensor — it’s a “fit and forget” item until symptoms or fault codes appear. As part of regular servicing, a quick visual once-over goes a long way: make sure the connector is seated, wiring isn’t chafed, and the O‑ring isn’t torn or perished. If cleaning is needed, use electronics-safe cleaner only, give the port a gentle spray, and avoid poking anything into the sensing hole.

Replacement is straightforward for most driveway tinkerers: switch the ignition off, pop the engine cover, unplug the connector, remove the fasteners, swap the sensor (with a fresh O‑ring), and refit. Don’t overtighten. After installation, a short idle and normal drive will let the ECU relearn trims, clearing stored codes with a scan tool helps. Sticking with a quality OEM-spec sensor ensures the Odyssey’s smooth, quiet manners and consistent fuel economy stay on song — whether it’s the school run or a long Kiwi/Aussie road trip.

• Typical symptoms: rough idle, flat spots, higher fuel use, Check Engine light (P0106–P0108)
• Quick checks: secure connector, intact vacuum hoses, no intake leaks post-service
• Best practice: use OEM-quality parts and a new O‑ring on replacement

Popular questions

Where is the MAP sensor on a 2019 Honda Odyssey?
It’s mounted on the intake manifold, usually near the throttle body under the plastic engine cover. Look for a small two‑bolt sensor with a single electrical connector. Access is typically from the top of the engine bay.

Can a dirty MAP sensor be cleaned, or should it be replaced?
Light contamination can often be addressed with electronics-safe cleaner and a gentle spray. If the sensor is oil-soaked internally, cracked, or repeatedly triggers codes after cleaning, replacement is the reliable fix. Always refit with a fresh O‑ring to prevent vacuum leaks.

What codes point to a MAP sensor fault on a 2019 Odyssey?
Common Honda codes are P0106 (MAP range/performance), P0107 (circuit low), and P0108 (circuit high). You might also see fuelling trims out of whack if there’s a vacuum leak. Confirm with live data before condemning the sensor.
