2009 Honda CR‑V MAP sensor — what it does and how to look after it

Yes, the 2009 Honda CR‑V is fitted with a MAP (Manifold Absolute Pressure) sensor. Honda’s 2007–2011 CR‑V Service Manual includes dedicated diagnostics and replacement procedures for the MAP sensor, with fault codes such as P0106, P0107 and P0108 tied directly to it. The Honda electronic parts catalogue for the RE‑series CR‑V also lists a MAP sensor mounted on the intake manifold. Independent workshop databases (e.g., ALLDATA and Mitchell 1) echo the same information for the 2.4‑litre K24Z engine used in this model.

On this CR‑V, the MAP sensor is the engine control unit’s window into intake manifold pressure. By measuring absolute pressure and temperature (with intake air temp measured separately on many variants), the ECU can figure out engine load and precisely manage fuel delivery and ignition timing. This “speed‑density” approach means the car doesn’t rely on a traditional hot‑wire MAF in most markets, the MAP sensor is the star of the show for smooth starts, tidy idle, and decent fuel economy across the rev range.

It’s not a high‑wear item, so it isn’t replaced on a schedule. That said, a tired or contaminated MAP sensor can cause rough idle, flat spots off the line, heavy fuel use, or a check‑engine lamp. During regular servicing under the bonnet, it’s worth a quick visual once‑over: make sure the electrical connector is snug, the wiring isn’t chafed, and the sensor’s O‑ring and mounting are sound. If there’s carbon or oil mist in the manifold passage, a light clean of the port with a sensor‑safe spray can help—avoid soaking the sensor body or poking at the sensing element.

• Typical clues of a crook MAP sensor: hard starting, sluggish acceleration, poorer kilometres per litre, unstable idle, and DTCs P0106–P0108.
• Replacement is straightforward: relieve pressure risk by switching off, unplug the connector, remove the fixing screws, lift out the sensor, fit a new O‑ring if required, and reinstall. Clear codes and allow the ECU to relearn idle on first start.
• Use a quality OEM or reputable aftermarket unit. If problems persist, check for vacuum leaks and brittle wiring before condemning new parts.

Look after the intake system—clean air filter, no split hoses—and the MAP sensor generally keeps doing its job without fuss for years on end, whether the CR‑V is doing the school run or a long Kiwi roadie.

Popular questions about the 2009 Honda CR‑V MAP sensor

Where is the MAP sensor located?

It’s typically mounted on the intake manifold near the throttle body, under the bonnet on the left‑hand side of the engine bay. Look for a small rectangular sensor with a three‑pin connector and one or two screws holding it down.

Does the 2009 CR‑V also have a MAF sensor?

Most 2009 CR‑V models in Australia and New Zealand run a speed‑density setup using the MAP sensor rather than a separate hot‑wire MAF. Some regional variants can carry different emissions hardware, but the MAP sensor is the primary load input for this generation.

Can the MAP sensor be cleaned, or should it be replaced?

If the issue is light contamination at the manifold port, a careful clean with a sensor‑safe aerosol can restore proper readings. If the sensor is electrically faulty or giving erratic data after checks, replacement is the go. Always inspect the connector and wiring before fitting a new unit.
