Bosch 0281002514 Pressure and Temperature Sensor

Bosch 0281002514 Pressure and Temperature Sensor

The Bosch 0281002514 is a high‑performance intake manifold pressure (MAP) sensor that also measures air temperature. Designed for modern internal combustion engines, it delivers precise data to the engine control unit (ECU), enabling optimal fuel delivery, ignition timing, and overall engine efficiency.

Key Functionalities

• Dual‑parameter sensing: Simultaneously measures manifold pressure and intake air temperature.
• Wide operating range: Supports pressures from vacuum to +2 bar (approximately 0–200 kPa) and temperatures from -40 °C to +120 °C.
• High accuracy: ±1% of full scale for pressure, ±3 °C for temperature.
• Fast response time: < 10 ms for pressure changes, ensuring real‑time engine management.
• Robust construction: Sealed housing protects against moisture, oil, and combustion gases.

Technical Specifications

Applications and Vehicle Compatibility

The 0281002514 is engineered for a broad spectrum of vehicles, including:

• Ford models such as the 3U1L9F479AA, BA/BF Falcon, and various turbocharged V8s.
• Chevrolet, Fiat, Iveco, and Volkswagen platforms that require accurate MAP data for advanced engine management.
• Commercial trucks like the Iveco Daily and Fiat Ducato, where precise boost pressure monitoring is critical.
• High‑performance sports cars and racing applications that demand rapid sensor response.

Installation Guidelines

1. Disconnect the battery: Prevent electrical shock during installation.
2. Remove the old sensor: Unscrew the existing MAP sensor from the intake manifold using a suitable socket set. Note any wiring harness connections.
3. Clean the mounting surface: Use isopropyl alcohol to remove oil or debris that could affect sealing.
4. Apply new O‑ring: Place a fresh NBR O‑ring on the sensor’s mating surface to ensure a leak‑free seal.
5. Screw in the new sensor: Tighten to manufacturer torque specifications (typically 10–12 Nm).
6. Reconnect wiring harnesses: Ensure proper polarity and secure connections.
7. Re‑connect the battery: Restore power and verify that the ECU recognizes the new sensor.

Troubleshooting Tips

• If the engine exhibits rough idle or misfires, check for vacuum leaks around the MAP sensor seal.
• A sudden drop in fuel economy may indicate a faulty temperature reading; verify the sensor’s voltage output with a multimeter.
• Persistent error codes related to MAP or intake air temperature should prompt inspection of the wiring harness for corrosion or disconnection.
