The 079800-7240 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 applications.

The 079800-7240 MAP sensor is extensively used across a wide range of Honda and Acura vehicles. Below is a comprehensive list of confirmed compatible applications:

Important: This sensor is compatible with a wide range of Honda and Acura models spanning approximately 2002 to 2011. Always verify fitment using your vehicle's VIN and exact engine code before purchasing.

A failing or faulty 079800-7240 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 or surge unexpectedly.

3. Poor Acceleration and Lack of Power
Inaccurate pressure readings lead to improper fuel delivery, resulting in delayed throttle response, hesitation during acceleration, and sluggish performance.

4. 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.

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

6. Engine Misfire
Faulty MAP data can cause the engine to misfire under load.

7. Failed Emissions Test
Inaccurate air-fuel ratio control leads to increased emissions, potentially causing the vehicle to fail emissions inspections.

Common causes of MAP sensor failure include:

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

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

• Short circuit in wiring

• Faulty sensor – internal component degradation over time

• Poor connections – loose terminals, corrosion, contamination, or damage

• Contamination – oil or debris buildup on the sensing element

• Heat exposure – prolonged exposure to high under-hood temperatures

When purchasing a replacement 079800-7240 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 079800-7240 is the primary reference, the Honda OEM equivalent is 37830-PNC-003.

Critical: Check your vehicle's VIN and engine code against the compatibility list. Physical fitment and electrical connector configuration must match exactly. This sensor features a 3-pin connector and is found on the engine inlet manifold.

The 079800-7240 is a manifold absolute pressure sensor that detects intake manifold pressure and converts it into an analog voltage signal for the ECU. The ECU uses this information to determine engine load, fuel delivery, ignition timing, and air/fuel ratio adjustments.

Material quality matters. This sensor features:

• Durable high-quality plastic housing for heat and vibration resistance

• Precision silicon-based sensing element with integrated amplifier

• OEM-grade construction meeting original specifications

Choose a supplier that offers:

• Warranty against manufacturing defects (minimum 1 year recommended)

• Quality assurance through professional testing and inspection

• Reputable brand with positive customer reviews

Consider replacing your MAP sensor if:

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

• You experience rough idling, poor acceleration, or poor fuel economy

• You encounter hard starting, stalling, or engine misfire

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

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

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

• Disconnect the negative battery terminal before beginning work

• Proper mounting – The sensor is typically mounted on the intake manifold or throttle body

• Electrical connection – Verify the 3-pin 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

While pricing varies between suppliers, consider the following:

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

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

• Premium options  typically offer better durability and more consistent performance

Choose suppliers who offer:

• Clear warranty terms (minimum 1 year recommended)

• 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 pins for straightness and integrity

• Confirm the sensor is designed for your specific vehicle application

• Verify the sensor features a 3-pin connector configuration
