2019 Honda CR‑V MAP Sensor: What it does and how to look after it

Technical sources confirm the 2019 Honda CR‑V does use a Manifold Absolute Pressure (MAP) sensor. Honda’s factory service information for the 2017–2021 CR‑V (PGM‑FI/engine control system sections) shows a MAP sensor fitted to the intake manifold, and Honda’s parts catalogues list a MAP sensor for both the 1.5‑litre turbo and the 2.4‑litre petrol variants. Standard OBD‑II diagnostics for this model also include MAP‑related DTCs such as P0106–P0108, which further verifies its presence and role.

The MAP sensor’s job is to measure the absolute pressure in the intake manifold so the ECU can work out engine load and fine‑tune fuel, ignition timing, and (on the 1.5T) turbo boost control. On the turbo model, it works alongside a charge‑pipe boost pressure sensor and, in many trims, a MAF sensor, giving the ECU accurate data across all driving conditions. It’s a small bit of tech that makes a big difference to smooth running, good fuel economy, and crisp throttle response.

There’s no fixed replacement interval for a MAP sensor on a 2019 CR‑V, but it’s smart to include it in routine servicing checks. A quick visual once‑over every 20,000–30,000 km to ensure the connector is snug, wiring isn’t chafed, and the O‑ring isn’t perished goes a long way. If the engine shows any of the following, the MAP sensor is worth a look:

• Rough idle, hesitate on take‑off, or flat spots under load
• Higher fuel use than usual
• Check engine light with codes like P0106, P0107, or P0108

Light contamination can sometimes be addressed with electronics‑safe sensor cleaner. Don’t poke the sensing port, and avoid harsh solvents. If there’s oil mist build‑up from PCV vapours or it’s throwing repeated codes, replacement is typically the better call. Use a quality OEM‑spec sensor, lightly lubricate the new O‑ring, seat it squarely in the manifold, and snug the fastener—no need to swing off the spanner. After refitting, clear codes and perform an idle relearn as per Honda service procedures.

It pays to rule out related issues at the same time: vacuum or boost leaks, split charge hoses (on the turbo), and poor grounds can all skew MAP readings. With a healthy MAP sensor and airtight intake, the 2019 CR‑V runs sweet as—smooth, efficient, and ready for the daily grind.

Does the 2019 CR‑V have a MAP sensor or only a MAF?

It has a MAP sensor on the intake manifold, and many trims also use a MAF sensor. The ECU blends these inputs (plus a boost sensor on turbo models) for accurate fueling and boost control.

What are the signs the MAP sensor needs attention on a 2019 CR‑V?

Common signs include rough idle, hesitant acceleration, poorer fuel economy, and a check engine light with codes like P0106–P0108. Always check for intake leaks and wiring issues too.

Should the MAP sensor be cleaned or replaced during regular servicing?

It’s not a scheduled replacement item, but a periodic inspection is wise. If lightly dirty, a careful clean with sensor‑safe cleaner may help. If faults persist or contamination is heavy, replacement with an OEM‑spec unit is recommended.
