Parts for your 2014 Honda Stream-Map sensor

2014 Honda Stream MAP sensor — what it does, where it is, and when to swap it

Based on technical documentation, the 2014 Honda Stream (RN6–RN9) is fitted with a Manifold Absolute Pressure (MAP) sensor. Honda’s Electronic Parts Catalogue for RN6–RN9 lists “Sensor Assy., MAP” (typical p/n 37830‑RNA‑A01) under the fuel injection group for R18A and R20A engines, and the Honda Stream Service Manual (Fuel and Emissions section) details MAP sensor inspection and diagnostics, including DTCs P0106, P0107 and P0108. These sources confirm the MAP sensor is relevant and used on this model.

On the Stream’s i‑VTEC engines, the ECU runs a speed‑density strategy, using the MAP sensor to read absolute pressure in the intake manifold. Along with intake air temperature, throttle position and engine speed, that pressure reading lets the ECU calculate air mass, command the right fuel and ignition timing, stabilise idle, and keep emissions hardware happy. There’s no separate MAF meter on most RN6–RN9 Streams because the MAP‑based system is robust, compact, and well suited to these engines across Aussie and NZ conditions.

While the MAP sensor isn’t a routine replacement item, it deserves a look during major servicing. Oil mist and carbon can collect in the sensor port or manifold passage, skewing readings and causing rough idle, flat spots, poor fuel economy, hard starting, or an illuminated MIL. Common fault codes include P0106 (range/performance), P0107 (low input) and P0108 (high input).

• Location: typically on the intake manifold near the throttle body, secured with small screws and sealed by an O‑ring.
• Service tip: inspect the connector for corrosion, ensure the vacuum passage to the sensor isn’t blocked, and check for cracked or loose hoses that can mimic a bad sensor.
• Cleaning: if light contamination is present, use electronics‑safe cleaner on the sensor port only, avoid soaking the transducer. If in doubt, replace.

Replacement is straightforward: disconnect the negative battery terminal, unplug the sensor, remove the screws, renew the O‑ring, and refit a quality OEM‑equivalent unit (genuine Honda/DENSO). Tighten the fasteners evenly to the factory spec, reconnect, clear codes, and perform an idle learn so the ECU settles quickly after the change. As part of preventative care every 40–60,000 kilometres, a quick inspection of the MAP sensor, the throttle body and associated vacuum paths can keep the Stream running sweet and economical.

• Does the 2014 Honda Stream use a MAP or a MAF?
  Honda specifies a MAP sensor on RN6–RN9 Streams with R‑series engines. The ECU uses speed‑density logic, so there’s no separate traditional MAF meter on most variants.
• Where is the MAP sensor on a 2014 Stream?
  It’s mounted on the intake manifold close to the throttle body, up top at the front of the engine bay. It’s a small black sensor with a 3‑pin connector and an O‑ring seal.
• Is it safe to drive with a dodgy MAP sensor?
  The engine will usually run but may use more fuel, feel sluggish, and risk catalyst damage over time. Prompt testing and repair is the smart move.
