VOLVO 21141943 / 20450693 MAP Sensor Specification

Genuine VOLVO Manifold Absolute Pressure (MAP) Sensor 21141943

Product Overview: The Genuine VOLVO Intake Manifold Absolute Pressure (MAP) Sensor (P/N: 21141943 / VOE21141943) is a precision electronic module that measures the air pressure and density forced into the cylinders by the turbocharger. By providing real-time data to the ECU, it enables precise fuel injection, EGR regulation, and boost control, which are essential for maintaining optimal engine power and fuel efficiency.

1. Core Technical Advantages

  • Silicon Piezoresistive Sensing: Micro-machined silicon diaphragm delivers instantaneous, high-accuracy pressure readings with zero lag.

  • Thermal & Chemical Resistance: Casing is built to endure harsh manifold environments, including extreme heat, soot, and oil mist.

  • Signal Condition Circuitry: Integrated matrix filters out high-frequency engine vibration and EMI for consistent voltage signal output.

  • Weatherproof Sealing: High-durability Viton O-ring prevents moisture and oxidation damage at the connection point.

3. Master Application Fleet Guide

This sensor is critical for maintaining turbocharger performance across various VOLVO platforms:

  • Crawler Excavators: EC210B, EC240B, EC290B, EC160B, EC180B, EW200B

  • Wheel Loaders: L110E, L120E, L150E

  • Articulated Haulers: A25D, A30D, A35D

4. Common Field Failure Symptoms

  • Power Loss/Limp Mode: Incorrect boost pressure data triggers the ECU to de-rate the engine, significantly limiting performance under load.

  • Black Smoke: Imprecise air-fuel ratio calculations cause incomplete combustion, visible as heavy black exhaust.

  • Rough Idling: Signal drift or intermittent connectivity leads to unstable engine idle and hesitant acceleration.

Best Practice Installation Advisory:
Always clean the intake manifold mounting surface of carbon and oil residue before fitting the new sensor. Replace the Viton O-ring for every installation to maintain a vacuum-tight seal. Apply dielectric grease to the connector pins and use Volvo Tech Tool to clear any stored boost-pressure fault codes after the repair is complete.
