2008 Honda CR‑V MAP Sensor: What it does and how to look after it

Technical sources confirm the 2008 Honda CR‑V is fitted with a MAP (Manifold Absolute Pressure) sensor. The Honda Service Manual for the 2007–2011 CR‑V (Fuel and Emissions section), OEM parts catalogues, and the model’s OBD‑II diagnostic coverage (DTCs P0106, P0107, P0108 for MAP circuit/performance) all identify a MAP sensor on the K‑series 2.4‑litre engine. So yes—this CR‑V uses a MAP sensor mounted on the intake manifold.

For this model, the MAP sensor is the ECU’s main way of measuring intake manifold pressure so it can calculate engine load. Paired with intake air temperature and engine speed, it lets the ECU dial in fuel, ignition timing, and idle control for smooth driving, decent economy, and low emissions. It’s a speed‑density system, which means there’s no separate MAF in most markets—the MAP does the heavy lifting.

It isn’t a scheduled replacement item, but it’s smart to give it a look during regular servicing—especially when the air filter, throttle body, or PCV system is being checked. Under the bonnet, the MAP sensor sits on the intake manifold near the throttle body, it’s a small, plug‑in sensor with an O‑ring seal. If the CR‑V shows a check‑engine light, rough idle, hard starting, or thirsty fuel use, scan for codes and inspect the MAP and its vacuum passage.

• Common symptoms of MAP issues: CEL on with P0106/P0107/P0108, sluggish acceleration, poor fuel economy, surging or stalling at idle.
• Quick checks: ensure the connector is clean and tight, wiring isn’t rubbed through, the O‑ring isn’t flattened, and there’s no oil sludge blocking the port.
• Cleaning: avoid soaking the sensor in harsh cleaners. If needed, use electronics‑safe spray on the tip and gently clear the manifold port.

Replacement is straightforward: disconnect the battery (optional but recommended), unplug the connector, remove the retaining fastener(s), lift the sensor, fit a fresh O‑ring if needed, and reinstall. Tighten to factory spec—snug, not gorilla‑tight. After replacement, clear any codes and perform an idle learn: warm the engine, all accessories off, then let it idle steadily for a few minutes so the ECU can settle trims.

A quality OEM or well‑reviewed aftermarket sensor is the go. As a rule of thumb, check the MAP and intake plumbing every 40,000–60,000 kilometres, or sooner if driving lots of dusty roads across Aus or NZ.

Popular questions

Where is the MAP sensor on a 2008 Honda CR‑V?
It’s on the intake manifold near the throttle body, under the bonnet. Look for a small rectangular sensor with one electrical plug and a single bolt or two small screws. Access is usually easy with basic hand tools.

Does a 2008 CR‑V have a MAF as well?
Most 2008 CR‑V models use a speed‑density setup, so there’s no separate MAF. The ECU relies on the MAP sensor, intake air temperature, and RPM to calculate airflow. Always check your specific market trim, but a standalone MAF is uncommon on this generation.

Do I need to do anything after replacing the MAP sensor?
Yes—clear any stored codes and let the ECU relearn. Warm the engine fully, switch off all accessories, and let it idle for a few minutes. A short drive cycle with gentle acceleration also helps fuel trims settle.
