2019 Honda Accord MAP Sensor — Purpose, Service and Replacement

Drawing on Honda’s factory service information, the Honda genuine parts catalogue, and common workshop databases (e.g., ALLDATA/Mitchell), the 2019 Honda Accord does use a MAP (Manifold Absolute Pressure) sensor across its engine options, including the 1.5‑litre turbo, 2.0‑litre turbo, and the hybrid. It’s a key input for engine management and, on the turbo models, also helps the ECU understand boost conditions.

The MAP sensor on a 2019 Accord measures pressure in the intake manifold so the ECU can figure out engine load and meter fuel and ignition timing accurately. On the turbo variants, it’s central to controlling boost and keeping things crisp under acceleration, on the hybrid, it helps the system transition smoothly between petrol power and electric assist. Because it reads actual manifold pressure, the ECU can adapt to altitude, weather, and small intake changes without fuss.

There’s no set replacement interval for a MAP sensor on this model. It’s a fit‑and‑forget item that’s checked when fault codes or symptoms pop up. Good servicing practice is to inspect the connector for corrosion, ensure the O‑ring seals properly, and keep the intake plumbing and PCV system healthy so oil mist and soot don’t gum up the sensor port. If scanning live data, they’ll typically see key‑on engine‑off readings near local barometric pressure, and noticeably lower kPa at idle.

• Typical warning signs: rough idle, hesitant throttle, lousy fuel economy, black smoke on hard throttle, or a check engine light with codes like P0106, P0107, or P0108.
• Basic replacement steps: disconnect the battery, unplug the connector, remove the retaining screw(s), lift the sensor, swap the O‑ring, seat the new unit, and snug the fastener(s). Don’t over‑tighten and don’t poke anything inside the port.
• Cleaning tip: if light contamination is suspected, a quick spritz with electronics‑safe cleaner is fine. Avoid harsh solvents and compressed air.

For the 1.5T and 2.0T, the MAP sensor lives on the intake manifold near the throttle body. Note there can also be a separate charge‑pipe pressure sensor—handy to know so the right part gets replaced. Choosing a quality OEM‑spec sensor keeps drivability sweet, emissions tidy, and fuel use in check. If in doubt, a quick scan and smoke test for intake leaks will save them chasing ghosts.

FAQs

Where is the MAP sensor on a 2019 Honda Accord?
It’s mounted on the intake manifold, generally near the throttle body. Turbo models may also have an additional charge‑pressure sensor in the intercooler piping—different job, similar look—so it pays to confirm which one they’re after.

What fault codes point to a bad MAP sensor?
Common ones include P0106 (range/performance), P0107 (low input), and P0108 (high input). Corroded connectors, split vacuum hoses, or intake leaks can trigger the same codes, so a visual check and smoke test are smart before replacing parts.

Does the MAP sensor need regular replacement?
No set interval. It’s replaced only if faulty or contaminated. During major services, a quick connector check, a look at live data, and ensuring the O‑ring seals properly is more than enough.
