2007 Honda Stream MAP sensor — what it does and how to look after it

Yes, the 2007 Honda Stream uses a MAP sensor. Honda’s Electronic Service Manual for the Stream RN6–RN9 (PGM‑FI section) details MAP sensor testing and values for both the R18A 1.8L and R20A 2.0L engines, and the Honda Electronic Parts Catalogue lists the MAP sensor as a serviceable item (common Honda p/n 37830‑RNA‑A01, with supersessions depending on market). This model runs a speed‑density PGM‑FI strategy, so there’s no MAF sensor, the MAP sensor is the primary engine load input.

On the 2007 Honda Stream, the manifold absolute pressure (MAP) sensor is the ECU’s eyes on what’s happening inside the intake manifold. By reading manifold vacuum/pressure, it lets the ECU juggle fuel and ignition for smooth idle, crisp throttle response and decent economy around town. Because the Stream’s system is MAP‑based, a healthy sensor is vital for cold starts, hill climbs, towing the kids’ gear, and everything in between.

The sensor itself is a small unit sitting on the intake manifold near the throttle body, sealed with an O‑ring and plugged in with a single connector. There’s no scheduled replacement in Honda’s maintenance charts, but it’s smart to check it during regular servicing. Typical trouble signs include a hunting idle, flat spots on take‑off, sootier exhaust than usual, and a thirsty fuel bill. The ECU often throws codes like P0106, P0107 or P0108 when the MAP reading is implausible.

Easy care tips that fit neatly into a service:

• Inspect the connector for corrosion or a loose latch, a quick spray of electronics‑safe cleaner won’t go astray.
• Check the manifold port isn’t gunked up with oil mist, wipe the bore gently without pushing debris inside.
• If removing the sensor, replace the O‑ring and don’t use sealant. Nip the bolts up snug, not gorilla‑tight.
• With a scan tool, key‑on/engine‑off should read near local barometric pressure (~100 kPa at sea level). Warm idle will typically show ~25–40 kPa.

If replacement’s on the cards, go for genuine or a reputable brand that matches the OE calibration. Disconnect the battery if preferred (radio code handy), swap the unit, clear any fault codes, and perform an idle relearn. For most Aussie and Kiwi drivers, a well‑looked‑after MAP sensor will run for years without drama, keeping the Stream perky and efficient across the kilometres.

Does the 2007 Honda Stream have a MAP or a MAF sensor?

It uses a MAP sensor. The 2007 RN6–RN9 Stream is a speed‑density PGM‑FI system, so there’s no separate MAF. The MAP signal, along with intake air temp and engine speed, handles fuel and ignition calculations.

Where is the MAP sensor on a 2007 Honda Stream?

It’s mounted on the intake manifold near the throttle body, secured with two small bolts and sealed by an O‑ring. There’s a single electrical connector that’s easy to spot with the bonnet up. R18A and R20A engines place it in roughly the same area.

What are common symptoms of a faulty MAP sensor on this model?

Rough or surging idle, hesitation under load, higher fuel use, and an illuminated check‑engine light. Scan tools often show DTCs P0106–P0108. If the manifold port is blocked or the connector is dirty, you can get similar symptoms, so a quick clean and retest can save unneeded parts.
