2007 Honda CR‑V MAP sensor: what it does and when to replace it

According to Honda’s factory information for the 2007 CR‑V (third‑generation, PGM‑FI petrol models), a Manifold Absolute Pressure (MAP) sensor is fitted to the intake manifold. This is documented in the Honda Service Manual for the 2007 CR‑V under the PGM‑FI/Emissions section (MAP Sensor), reflected in the Honda wiring diagrams, and supported by the model’s OBD‑II diagnostic chart listing MAP‑related DTCs P0106, P0107 and P0108. So yes, a MAP sensor is used on the 2007 Honda CR‑V.

The MAP sensor measures the absolute pressure inside the intake manifold so the ECU can work out engine load. On the 2007 CR‑V’s i‑VTEC engine, that signal is key for calculating fuel delivery, ignition timing and idle control, and for keeping emissions in check. In short, it helps the car pull cleanly from low revs, return decent fuel economy and avoid pinging.

While the MAP sensor isn’t a scheduled replacement item, it’s smart to include a quick check during routine servicing. Under the bonnet, the sensor sits on the intake manifold near the throttle body and seals with an O‑ring. Oil mist and dust can film over the sensing port over time. A light clean with electronics‑safe cleaner (no scrubbing, no compressed air straight into the port) can restore a lazy sensor. Inspect the connector for green corrosion, ensure the terminals are tight, and replace a flattened or cracked O‑ring to prevent false readings caused by air leaks.

Replacement is straightforward and best done with a quality OEM‑equivalent sensor. With the engine cool, remove the engine cover, unplug the connector, and undo the mounting screws. Swap in the new sensor with a fresh O‑ring, snug the screws (don’t over‑tighten), reconnect, then clear any codes and perform an idle relearn as per the service manual. A quick scan‑tool check of live data helps: at key‑on, engine‑off you’ll typically see around ambient pressure, and at warm idle a steady lower kPa reading.

If the CR‑V shows a rough idle, poor fuel economy, flat spots, hard starting or an illuminated MIL with codes P0106–P0108, the MAP sensor should be high on the inspection list. Left ignored, a drifting MAP reading can make the engine feel doughy and guzzle more petrol than it should.

• Common clues: rough idle, hesitation, heavy fuel use, black smoke, hard starts, MIL on (P0106–P0108).
• Good practice: clean lightly, check the O‑ring, verify wiring, and use scan‑tool data before condemning the sensor.

Popular questions

Where is the MAP sensor on a 2007 Honda CR‑V?
It’s mounted on the intake manifold near the throttle body, secured with two small screws and a single electrical connector. An O‑ring seals it to the manifold. Access is under the engine cover, most techs can swap it out with basic hand tools.

What are the signs the MAP sensor needs replacing versus just cleaning?
If there’s light oil mist or dust build‑up, a gentle clean with electronics‑safe cleaner can sharpen its response. Persistent issues like DTCs P0106–P0108, out‑of‑range voltage, or erratic kPa readings at idle often point to a failing sensor or wiring fault, in which case replacement and proper diagnosis are wise.

Does the 2007 CR‑V have a MAF sensor as well?
Most 2007 CR‑V petrol models in our market use a speed‑density system, so there’s no separate hot‑wire MAF sensor. The ECU estimates airflow from the MAP sensor, intake air temperature, throttle position and engine speed. Always confirm by VIN if unsure.
