2017 Honda CR‑V MAP sensor — what it does and when to replace it

Yes, the 2017 Honda CR‑V uses a MAP (Manifold Absolute Pressure) sensor. Technical sources that confirm this include the Honda CR‑V (2017–2019) Service Manual (Fuel & Emissions > PGM‑FI), which lists MAP sensor inspection and R&I procedures, and Honda technical training for the 1.5‑litre turbo L15B engine noting a T‑MAP (pressure + temperature) sensor on the intake manifold. The OBD‑II section also documents MAP‑related DTCs (P0106, P0107, P0108), further showing it’s a monitored component on both the 1.5T and 2.4L models.

On this CR‑V, the MAP sensor measures absolute pressure in the intake manifold so the ECU can work out engine load, fuel delivery, and ignition timing. On the 1.5‑litre turbo, it also helps manage boost. Even with a MAF fitted, Honda still uses the MAP for load modelling, EGR and transient response. If it goes out of whack, drivers may see a rough idle, lazy throttle, higher fuel use, a check‑engine light, or limp behaviour when boosting.

Replacement and care are straightforward, and it’s a tidy bit of preventative maintenance during servicing. The sensor sits on the intake manifold (near the throttle body on the 1.5T, on the manifold runner on the 2.4L). It’s a 5‑volt pressure transducer, so good power/earth and a clean vacuum port are key.

• Inspection: scan for MAP‑related codes (P0106–P0108) and compare live data (kPa) to barometric pressure KOEO. Look for implausible readings or jittery signals.
• Cleaning: if the port is sooty or oily, remove the sensor and gently clean the tip/port with electronics‑safe, no‑residue cleaner. Don’t poke the diaphragm or drown it in solvent.
• Replacement: if readings are off or codes return, fit a quality sensor with a fresh O‑ring. Disconnect the battery if required by workshop process, refit, and clear codes. A throttle/idle relearn via scan tool may be recommended.

There’s no fixed change interval, but checking MAP data at major services (say, every 20,000–30,000 km) is cheap insurance—especially on the turbo where accurate pressure data keeps boost and fueling happy. Keeping the air filter fresh and the PCV system tidy also helps the MAP stay clean under the bonnet.

Popular questions

Does a 2017 Honda CR‑V have both a MAP and a MAF sensor?
Most do. The 1.5‑litre turbo uses a MAF in the air intake and a T‑MAP on the manifold, plus a separate boost/charge pressure sensor. The 2.4L model also features a MAP for load calculation and diagnostics. Honda’s engine management blends these signals for smooth driveability and emissions control.

Where is the MAP sensor on a 2017 CR‑V?
It’s mounted on the intake manifold. On the 1.5T, look near the throttle body at the top/front of the engine. On the 2.4L, it’s on the manifold runner area. There’s also a pressure sensor on the charge pipe of the turbo model—don’t mix the two when diagnosing.

Can a dirty MAP sensor cause poor fuel economy?
Absolutely. If the sensor under‑reads or lags because of oil mist or carbon at the port, the ECU can misjudge load, leading to rich mixtures, rough idle and flat spots. A quick inspection and careful clean can restore crisp response and better economy, if readings stay off, replacement is the go.
