2010 Honda Stream MAP sensor: purpose, upkeep and when to replace

Based on Honda technical documentation, the 2010 Honda Stream (RN6–RN9, R18A 1.8L and R20A 2.0L i‑VTEC) does use a Manifold Absolute Pressure (MAP) sensor. The Honda Electronic Service Manual for these models shows the MAP sensor in the engine control system diagram and lists DTCs P0106, P0107 and P0108 for MAP faults. Honda’s Electronic Parts Catalogue also lists a MAP sensor for RN6–RN9 vehicles (commonly referenced under Honda P/N 37830‑RNA‑A01 for these engines). So, a MAP sensor is absolutely relevant on this vehicle.

On the 2010 Honda Stream, the MAP sensor is the ECU’s barometer inside the manifold. It reads intake manifold pressure so the ECU can work out engine load and calculate fuel, ignition timing and EGR behaviour. Unlike some makes that rely on a MAF, these R‑series Hondas run a speed‑density strategy, with the MAP sensor front and centre for smooth idle, crisp throttle response and good fuel economy.

As part of routine servicing, the MAP sensor isn’t a scheduled replacement item, but it’s worth a quick check. A visual once‑over of the connector and wiring for corrosion or chafing, and a scan of the live data is smart at major intervals. Key on, engine off, the MAP reading should be close to local barometric pressure (about 95–102 kPa at sea level in Aus/NZ). At a hot idle, expect roughly 28–40 kPa on a healthy engine. Odd readings or fault codes like P0106–P0108 point to trouble.

If the sensor looks grubby with oil mist, a careful clean with electronics‑safe MAF/MAP cleaner can help. Don’t poke the sensing port or touch the diaphragm. Let it dry fully before reinstalling. On this model the sensor bolts directly to the intake manifold with an O‑ring—there’s no vacuum hose to perish—so make sure the O‑ring isn’t flattened or nicked. Lightly oil the O‑ring, seat the sensor squarely and tighten the fasteners to the service‑manual spec (don’t overdo it).

Replacement is straightforward: disconnect the plug, remove the screws, swap the sensor and refit. After replacement, the ECU may need a short relearn drive so idle and fuel trims settle. Sticking with a genuine or quality aftermarket sensor avoids flaky readings that can chew through fuel or make the Stream feel doughy off the line.

• Common signs of a crook MAP sensor: sluggish performance, rough idle, black exhaust smoke, poor economy, hard starts, and an engine light with P0106/P0107/P0108.

Looked after properly, the MAP sensor helps the 2010 Honda Stream deliver the easy, economical motoring it’s known for across Australia and New Zealand.

Does the 2010 Honda Stream have both a MAF and a MAP sensor?

No—these R‑series engines (R18A/R20A) use a MAP‑based speed‑density setup rather than a MAF. There’s an intake air temperature sensor, but airflow is inferred from manifold pressure, rpm and temperature, with the MAP sensor doing the heavy lifting for load calculation.

Is it safe to drive with a faulty MAP sensor on a 2010 Honda Stream?

It will usually run, but not happily. A dodgy MAP reading can cause rich mixtures, rough running and higher fuel use. Prolonged driving risks damaging the catalytic converter. Best to diagnose promptly and sort the sensor or wiring.

How can an owner quickly check the MAP sensor at home?

With a basic OBD‑II scanner, look at the MAP value. Key on, engine off should read close to local barometric pressure. At idle, expect around 28–40 kPa. If values are implausible or jumpy, inspect the connector and consider further testing or replacement.
