2022 Honda CR‑V MAP sensor: what it does, why it matters, and how to look after it

Based on Honda’s 2022 CR‑V Service Information (PGM‑FI, Fuel and Emissions) and the official Honda parts catalogue for AU/NZ models, the 2022 Honda CR‑V is fitted with a MAP (Manifold Absolute Pressure) sensor. Both the 1.5‑litre VTEC Turbo and the 2.0‑litre i‑VTEC petrol engines employ a MAP sensor, and the hybrid powertrain also uses MAP data for engine and EGR control. Technical notes from NTK/NGK and Bosch on MAP sensor operation align with Honda’s use: the MAP sensor feeds manifold pressure to the ECU for load, ignition and fuel calculations, and on turbo models also tracks boost.

In this CR‑V, the MAP sensor measures pressure inside the intake manifold. The ECU blends that pressure signal with intake air temperature, throttle position and, on the 1.5T, the MAF signal to determine how much fuel to inject and how to time the spark. Under the bonnet, that translates to smoother cold starts, crisp throttle response and better fuel economy on Aussie and Kiwi roads. On the turbo, accurate MAP data is also critical for controlling boost and avoiding knock.

There’s no fixed replacement interval for a MAP sensor in Honda’s servicing schedule, it’s a “replace on condition” item. That said, it’s smart to give it some attention during regular services:

• Check for split or dislodged vacuum hoses nearby, and inspect the sensor’s O‑ring for hardening or flattening.
• If drivability is off (rough idle, flat spots, high fuel use), scan for DTCs like P0106, P0107, P0108 and compare live data. Key‑on/engine‑off should read around local barometric pressure, warm idle will show a lower kPa on non‑turbo and fluctuate on turbo.
• Light deposits at the port can be carefully cleaned with electronics‑safe cleaner, avoid soaking the sensor element. If readings remain erratic, replacement is the go.

Replacing the MAP sensor is straightforward: remove the engine cover, unplug the connector, undo the fastener(s), swap the sensor with a fresh O‑ring, and snug the bolt to the Honda spec. Always clear codes and road‑test. Using quality OEM‑equivalent sensors keeps the ECU happy and helps maintain fuel economy, emissions and that familiar Honda smoothness.

Popular questions about the 2022 Honda CR‑V MAP sensor

Where is the MAP sensor on a 2022 CR‑V?
It’s mounted on the intake manifold. On the 1.5T, there’s also a separate charge/boost pressure sensor in the intake tract, but the MAP sensor itself sits at the manifold so the ECU can read vacuum and boost right where cylinders breathe.

What are the signs of a failing MAP sensor?
Common clues include a rough idle, sluggish take‑off, poor fuel economy, black smoke on accel, and a check‑engine light with codes like P0106–P0108. If the sensor is reading wrong, the ECU may over‑ or under‑fuel, which drivers will feel as hesitation or surging.

Can the MAP sensor be cleaned or should it be replaced?
Minor port contamination can be cleaned with electronics‑safe spray, but if live data is unstable, out of range, or codes return after cleaning, replacement is the sensible fix. There’s no scheduled change interval—only replace when diagnosis points to the sensor.
