Parts for your 2015 Honda Odyssey-Map sensor

2015 Honda Odyssey MAP sensor — is it fitted and what does it do?

Yes, the 2015 Honda Odyssey is fitted with a Manifold Absolute Pressure (MAP) sensor. Technical references that confirm this include the 2011–2017 Honda Odyssey Service Manual (Fuel and Emissions, PGM‑FI System: MAP Sensor diagnostics for DTCs P0106/P0107/P0108), Honda’s parts catalogues for the 2015 Odyssey (listing a MAP sensor assembly — part number varies by VIN, commonly in the 37830‑R70‑A0x family), and professional repair databases such as Mitchell1/ProDemand and ALLDATA, which detail MAP input being used by the ECU for load calculation on the J‑series 3.5‑litre V6.

On the 2015 Odyssey, the MAP sensor sits on or near the intake manifold and constantly reads the pressure/vacuum inside. The ECU blends that reading with engine speed, intake air temperature and throttle data to calculate how much fuel to inject and when to spark. That’s how it keeps starts crisp on cold mornings, fuel economy tidy on the school run, and emissions in check across Aussie and Kiwi conditions.

While the MAP sensor isn’t a high-wear item, it does live a hard life under the bonnet. Oil vapour and dust can skew its readings over time, knocking drivability about. Common signs of a grumpy MAP sensor include:

• Rough idle, hesitation, or flat spots on take-off
• Higher-than-usual fuel use and a sooty tailpipe
• Check Engine Light with codes like P0106, P0107 or P0108

As part of routine servicing on a 2015 Odyssey, it’s worth giving the MAP sensor and its connector a look every 30,000–50,000 km. If there’s oil mist or grime on the sensing port, use proper electronics-safe cleaner (not carby cleaner) and let it fully dry. Check the harness for chafes and the O‑ring seal for cracks.

If replacement is needed, it’s a straightforward job with basic tools:

1. Ignition off and battery negative disconnected
2. Remove the engine cover, then unplug the sensor connector
3. Undo the mounting screws/bolts and lift the sensor straight out
4. Lightly oil a new O‑ring, seat the new sensor squarely, and snug the fasteners
5. Reconnect the plug, refit the cover, reconnect the battery, and clear any stored codes

A quality OEM‑spec sensor will restore proper load readings so the ECU can trim fuel and timing correctly. After fitting, a short drive cycle helps the ECU relearn. Keeping the air filter fresh and the PCV system healthy will also help the MAP sensor stay clean and accurate for the long haul.

Popular questions about the 2015 Honda Odyssey MAP sensor

Where is the MAP sensor located on a 2015 Odyssey?
It’s mounted on the intake manifold area, towards the top of the engine under the plastic cover. Look for a small rectangular sensor with a two‑ or three‑pin connector and a single O‑ring seal into the manifold. Access is typically from above with the engine cover off.

Can a MAP sensor be cleaned, or should it be replaced?
Light contamination can often be sorted with electronics-safe sensor cleaner. If the sensor is oil-soaked internally, has cracked housing or keeps throwing P0106/P0107/P0108 after cleaning and wiring checks, replacement is the smart move. Use an OEM-quality unit and a fresh O‑ring to avoid vacuum leaks.

What happens if I drive with a faulty MAP sensor?
The Odyssey will usually fall back to a limp strategy, which can mean poor fuel economy, sluggish performance and increased emissions. Prolonged driving like that isn’t ideal, as rich mixtures can damage the catalytic converter. Best to diagnose and fix it promptly.
