2013 Honda Stream MAP Sensor — What It Does and How to Look After It

Based on Honda technical literature and the Honda Electronic Parts Catalogue for the RN6–RN9 Stream (2013 model year, R18A/R20A engines), this vehicle is equipped with a Manifold Absolute Pressure (MAP) sensor mounted on the intake manifold. Honda’s service information for these engines describes a speed‑density control strategy that relies on the MAP sensor, and lists MAP‑related diagnostic trouble codes (P0106–P0108) applicable to the model. So yes, the 2013 Honda Stream uses a MAP sensor, and it’s a relevant service item when chasing driveability or economy issues.

The MAP sensor measures the pressure (vacuum) inside the intake manifold. The ECU blends that signal with intake air temperature, throttle angle and engine speed to calculate how much fuel to deliver and when to fire the spark. On a 2013 Honda Stream, that translates to crisp throttle response, tidy fuel economy and lower emissions when the sensor is reading clean and true. Because the sensor sits right where crankcase vapours and manifold pulses live, it can get contaminated over time, nudging readings out of whack and making the car feel a bit doughy off the line or thirsty on longer runs.

While the MAP sensor isn’t a scheduled replacement item, it’s smart to give it attention during servicing if symptoms crop up. A quick visual check under the bonnet for a cracked connector, perished O‑ring, or oil residue at the sensor port can save a lot of guesswork. If light contamination is present, remove the sensor carefully and clean the port with electronics‑safe cleaner (not carb cleaner), letting it dry fully before refitting. Avoid poking anything into the sensing hole. If faults persist or DTCs return, replacement is straightforward and typically restores smooth idle and proper shift timing on auto models. After refitting, clear codes and allow the ECU to relearn with a short mixed drive. Many owners notice improved fuel consumption over the next few kilometres as trims settle.

• Common clues of a tired MAP sensor:
  • Rough idle or stalling at lights
  • Flat spots on take‑off or surging on cruise
  • Heavier fuel use and a whiff of rich exhaust
  • Hard starts when hot
  • Check Engine Light with P0106, P0107 or P0108

1. Confirm fault codes and live data (MAP kPa vs. barometric pressure, key‑on engine‑off).
2. Inspect connector, wiring and the sensor O‑ring for damage.
3. Clean lightly if fouled, replace if readings remain erratic.
4. Refit, clear codes, and perform a short relearn drive.

Popular questions about the 2013 Honda Stream MAP sensor

Where is the MAP sensor on a 2013 Honda Stream?
It’s fitted on the intake manifold, typically on the top or side near the throttle body. Look for a small black sensor with a two‑ or three‑pin connector and a single O‑ring seal. Access is usually straightforward with basic hand tools, so checks can be done during routine servicing without stripping half the bay.

What symptoms point to a failing MAP sensor?
Owners often report a rough or hunting idle, lazy throttle response and higher fuel use. The Check Engine Light may appear with codes like P0106–P0108. Because those signs can overlap with vacuum leaks or tired spark plugs, it’s wise to confirm with scan data before swapping parts.

Can the MAP sensor be cleaned instead of replaced?
Yes—if the sensor is just oily at the port. Use electronics‑safe cleaner and let it dry fully. If the readings stay inconsistent, or there’s internal damage or water ingress, replacement is the reliable fix. Given the role it plays in fuelling, a healthy MAP sensor quickly pays for itself in smoother running and better economy.
