🔧 Product Description

Genuine Honda Manifold Absolute Pressure Sensor - Part Number: 37830-RNA-A01

A genuine used Honda Marine manifold absolute pressure sensor for selected inline and V6 EFI four-stroke outboards.

The MAP sensor measures pressure within the intake manifold. The engine control module uses this signal to calculate engine load, fuel-injection duration, ignition timing and acceleration enrichment.

⚙️ Key Features

  • Genuine used Honda MAP sensor
  • Correct OEM part number 37830-RNA-A01
  • Used across selected Honda 40HP to 250HP outboards
  • Provides intake-manifold pressure information to the ECU
  • Original Honda electrical connector and calibration

🚤 Compatibility

Commonly used on

  • Honda programmed fuel-injection systems
  • Intake-manifold pressure monitoring circuits

Typically suits

  • Engine models:
  • Honda BF40D and BF40E
  • Honda BF50D
  • Honda BF60A
  • Honda BF75DK3 and BF75DK4
  • Honda BF80A and BF80AK1
  • Honda BF90DK4 and BF90DK5
  • Honda BF100A and BF100AK1

  • Model groups whose intake-system diagram specifies 37830-RNA-A01
  • HP Range: Approximately 40HP - 250HP
  • Engine Type: Honda EFI four-stroke outboard
  • Year Range: Model and frame-serial dependent

🔌 Function

The sensor converts manifold pressure into a variable voltage signal. The ECU compares this signal with engine speed, throttle position and temperature inputs to determine engine load.

⚠️ Common Signs of Failure

  • Engine is difficult to start
  • Idle speed is unstable
  • Engine hesitates during acceleration
  • Fuel consumption increases
  • Engine enters reduced-power mode
  • MAP diagnostic code is stored
  • Sensor output remains fixed or outside specification
  • Vacuum passage or sensor port is restricted
