22627-AA360 MAP Sensor Intake Manifold Absolute Pressure Sensor 22627-AA370/22627-AA380/079800-7620/5S12218/898009-4180/3089953

The 22627-AA360 MAP sensor is compatible with and can be substituted by the following OEM and equivalent part numbers:

Note: Always verify compatibility with your specific vehicle application before purchase. Cross-reference numbers are provided for reference purposes only and do not guarantee fitment across all listed vehicles.

The 22627-AA360 MAP sensor is specifically engineered for and widely used across the following vehicle platforms. This sensor is designed for turbocharged (forced induction) applications and is not compatible with naturally aspirated engines.

Important: This sensor is specifically for turbocharged Subaru models. Naturally aspirated variants require a different sensor. Always verify fitment using your vehicle's VIN and exact engine code before purchasing.

A failing or faulty 22627-AA360 MAP sensor can manifest through a variety of drivability and performance issues. Early recognition of these symptoms can prevent more serious engine damage and costly repairs.

1. Illuminated Check Engine Light
The most common indication of a MAP sensor issue. The ECU detects abnormal voltage signals from the sensor and triggers the warning light. Common diagnostic trouble codes (DTCs) associated with MAP sensor failure include:

• P0106 – MAP/Barometric Pressure Circuit Range/Performance

• P0107 – MAP Sensor Circuit Low Input

• P0108 – MAP Sensor Circuit High Input

2. Rough or Unstable Idle
A faulty MAP sensor disrupts the air-fuel mixture, causing the engine to idle roughly, jitter, or struggle to maintain a steady RPM.

3. Engine Hesitation and Poor Acceleration
Inaccurate pressure readings lead to improper fuel delivery, resulting in delayed throttle response, hesitation, or stuttering when pressing the accelerator pedal.

4. Engine Misfires or Knocking
Incorrect pressure readings can lead to improper ignition timing and fueling, resulting in engine misfires or knocking under load.

5. Difficulty Starting or Engine Stalling
The engine may become difficult to start, or may stall after starting, due to incorrect cranking fuel mixture calculation.

6. Poor Fuel Economy
When the MAP sensor provides incorrect load data, the ECU may compensate by delivering an excessively rich or lean fuel mixture, significantly reducing fuel efficiency.

7. Engine Surging
Inconsistent MAP signals during throttle changes can cause the engine to surge unexpectedly.

Common causes of MAP sensor failure include:

• Open circuit in wiring between the MAP sensor and ECU/PCM

• Short circuit in wiring between the MAP sensor and ECU/PCM

• Faulty MAP sensor – internal component degradation

• Faulty ECU/PCM – less common but possible

• Intermittent faults – often caused by poor contact in the sensor's or PCM's connector

• Intake air leaks – causing false MAP readings

When purchasing a replacement 22627-AA360 MAP sensor, consider the following factors to ensure you select the right component for your vehicle.

Always confirm your vehicle's original equipment (OE) part number before purchasing. While 22627-AA360 is the primary reference, some vehicles may also use 22627AA310 as a compatible or superseded part number.

Critical: Check your vehicle's VIN and engine code against the compatibility list. Physical fitment and electrical connector configuration must match exactly. This sensor is designed specifically for turbocharged models. Naturally aspirated variants require a different sensor.

The 22627-AA360 is a 3.0 bar absolute pressure sensor. Earlier sensors (such as 22627AA170) could only read accurately to 2.5 bar absolute, which limited mapping to approximately 1.4 bar of boost. The 22627-AA360 provides additional headroom for higher boost applications, allowing for approximately 1.5–2.0 bar of boost pressure.

Using a sensor with an incorrect pressure rating will result in inaccurate readings and poor engine performance. If your vehicle is tuned for higher boost levels, this sensor provides the necessary measurement range.

The 22627-AA360 features a 3-terminal connector configuration:

• Connector Gender: Male

• Terminal Gender: Male

• Terminal Type: Blade

• Connector Type: Plug In

• Port Quantity: 1

Verify that your vehicle's wiring harness connector matches this configuration.

Material quality matters. This sensor features:

• Durable composite plastic housing for heat and vibration resistance

• Piezoelectric sensing element with hybrid IC for signal amplification

• Precision assembly using extensive robotics for consistent quality

• 100% product inspection from raw material to finished product

OEM-grade sensors are engineered for precision performance, durability, and a long service life. Choose a reputable manufacturer that meets or exceeds OE fit, form, and function.

Consider replacing your MAP sensor if:

• Your vehicle is throwing P0106, P0107, or P0108 diagnostic trouble codes

• You experience rough idling, poor acceleration, or decreased fuel efficiency

• You encounter engine misfires, hard starting, or stalling

• Your vehicle has significant mileage – sensors typically degrade over time

• The sensor shows signs of physical damage, corrosion, or contamination

Professional installation is recommended for optimal results. Key installation considerations include:

• Proper mounting – the sensor mounts above the turbo inlet

• Thread sealer – use provided thread sealer when installing

• Hand-tighten first – thread by hand until tight before using tools

• Electrical connection – verify the connector is clean and free of corrosion

• Check for poor connections – thoroughly inspect connectors for looseness, poor contact, corrosion, contamination, or damage

• Clear diagnostic codes – after installation, clear any stored codes; if the fault was intermittent, the PCM memory may need to be cleared

Before replacing the sensor, inspect the wiring harness:

• Check for open circuits in wiring between the MAP sensor and ECU/PCM

• Check for short circuits

• Inspect connectors for corrosion, contamination, deterioration, or damage

• If the fault is intermittent, poor contact in the sensor's or PCM's connector may be the cause

This sensor is a premium component and is priced accordingly. As noted in enthusiast communities, it is "prohibitively expensive to buy new". While pricing varies between suppliers:

• OEM-grade quality options provide the best balance of quality and value

• Extremely low-priced units may use inferior materials or lack proper calibration

• Premium options (genuine or high-quality equivalents) offer better durability and more consistent performance, especially important for tuned/high-boost applications

Choose suppliers who offer:

• Clear warranty terms (minimum 12 months recommended; some offer 3 years/36,000 miles)

• Hassle-free return policies

• Compatibility guarantees (with VIN verification)

Before installing the new sensor:

• Compare the new unit visually with the old one – dimensions and connector should match

• Check that the part number on the new sensor matches your requirements

• Inspect the connector terminals for straightness and integrity

• Confirm the sensor is rated for 3.0 bar absolute pressure measurement

• Confirm the sensor is for turbocharged applications
