The 0281002437 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 0281002437 MAP sensor is widely used across multiple vehicle manufacturers and engine platforms. Below is a comprehensive list of confirmed compatible applications:

Important: This sensor is compatible with over 1,100 vehicle variants. Always verify fitment using your vehicle's VIN and exact engine code before purchasing.

A failing or faulty 0281002437 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 and direct indication of a MAP sensor issue. The Powertrain Control Module (PCM) 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

• P0105 – MAP/Barometric Pressure Circuit Malfunction

2. Rough Idle and Engine Surging
A faulty MAP sensor disrupts the air-fuel mixture, causing the engine to idle roughly or surge unexpectedly. The engine may stumble or stall when coming to a stop.

3. Hesitation and Sluggish Acceleration
Inaccurate pressure readings lead to improper fuel delivery, resulting in delayed throttle response, hesitation during acceleration, or a general lack of power.

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. Black Smoke from Exhaust
A rich fuel mixture caused by faulty MAP sensor readings often results in black smoke emitting from the tailpipe, particularly under acceleration.

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

7. Engine Knocking or Pinging
Incorrect ignition timing resulting from faulty MAP data can cause engine knocking or pinging sounds under load.

8. Hard Starting
The engine may become difficult to start, particularly when cold, due to improper fuel mixture calculation.

9. Spark Plug Fouling
A persistently rich fuel mixture can coat spark plugs with a white powdery substance, leading to misfires and further performance degradation.

MAP sensors most commonly fail due to:

• Age and wear – Internal components degrade over time

• Moisture ingress – Water intrusion damages internal circuitry

• Contamination – Oil or debris buildup on the sensing element

• Vacuum leaks – Leaks in the intake system or vacuum hoses can affect pressure readings

• Electrical issues – Damaged wiring, corroded connectors, or poor ground connections

When purchasing a replacement 0281002437 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 0281002437 is the primary reference, some vehicles may use functionally similar but physically different sensors. Cross-reference numbers such as 93171176, 24459853, and 73503657 may appear on compatible units.

Critical: Check your vehicle's VIN and engine code against the compatibility list. Physical fitment and electrical connector configuration must match exactly.

The 0281002437 is a 3-bar (300 kPa) absolute pressure sensor. This pressure range is specifically designed for turbocharged diesel applications. Using a sensor with an incorrect pressure rating will result in inaccurate readings and poor engine performance.

This part number is a T-MAP sensor, meaning it integrates both pressure and temperature sensing in one unit. Ensure your replacement sensor includes the temperature sensing function if your vehicle's system requires it. A standard MAP sensor without temperature sensing will not function correctly as a replacement.

Material quality matters. The sensor housing is typically constructed from ABS plastic, but the quality of internal components varies significantly between manufacturers. High-quality sensors feature:

• Robust piezoelectric sensing elements

• Reliable 4-pin connector terminals

• Heat and vibration-resistant construction

• Resistance to oils, fuels, and other automotive fluids

While OEM-equivalent sensors may offer cost savings, ensure that any replacement meets or exceeds the original specifications. Consider:

• Accuracy specifications – Look for sensors with ±0.2V or better accuracy

• Temperature range – Ensure the sensor operates from -40°C to at least 130°C

• Pressure range – Verify 20-300 kPa coverage

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

• Proper mounting – The sensor uses a flange mount configuration

• Correct torque – Over-tightening can damage the sensor or sealing ring

• Seal ring – Ensure the replacement includes or requires a proper seal ring

• Electrical connection – Verify the 4-pin connector is clean and free of corrosion

• ECU calibration – Some installations may require ECU recalibration to recognize the new sensor

The 0281002437 features a 4-pin connector. Verify that your vehicle's wiring harness connector matches this configuration. Some vehicles may use different connector styles even with the same pressure rating.

When purchasing, confirm what is included in the package. Typically, the sensor is supplied as a standalone unit. Some suppliers may include:

• Mounting hardware

• Seal ring

• Installation instructions (though often not included)

While pricing varies significantly between suppliers, consider the following:

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

• Mid-range options often provide the best balance of quality and value

• Premium options typically offer better durability and more consistent performance

Choose suppliers who offer:

• Clear warranty terms

• 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
