Manifold Absolute Pressure (MAP) Sensors

Precision Engineered to Champion the Independent Aftermarket

VXPRO MAP Sensors are designed to deliver OE-accurate air pressure readings to the engine control unit (ECU), enabling precise fuelling, ignition timing, and turbo boost regulation. Built for durability and precision, our sensors offer consistent performance across a wide range of naturally aspirated and turbocharged engines.

Backed by a 5-year warranty and supported by TechASSIST and StockASSIST, VXPRO MAP Sensors help independent workshops complete diagnostics and repairs with confidence — and Champion the Aftermarket with every job.

TechASSIST: Product Support and Information

MAP sensors play a critical role in real-time engine control. A functioning sensor: Measures intake manifold pressure, which the ECU uses to calculate air mass and fuel delivery Supports turbocharger boost control, ensuring efficient performance and preventing overboost Affects ignition timing, improving throttle response and preventing detonation Influences emissions and fuel economy, especially in high-load and cold-start conditions Works in conjunction with MAF or IAT sensors on many engine platforms A faulty MAP sensor can disrupt multiple systems — and if readings are off, engine efficiency and drivability suffer.

Why Do They Fail?

MAP sensors are exposed to pressure, heat, and sometimes contamination. Common causes of failure include:

  • Internal sensor degradation over time, leading to signal drift or incorrect readings

  • Blockages from oil mist or carbon deposits in the intake tract

  • Vacuum leaks or split hoses (on sensors with remote mounting)

  • Wiring faults or corroded connectors, especially in underbonnet environments

  • Water or moisture ingress through faulty seals or cracked housings

Symptoms of a Faulty MAP Sensor

  • Rough idle or hesitation during acceleration

  • Poor fuel economy, especially at cruising speeds

  • Check Engine Light (MIL) illuminated, with codes such as P0105–P0109

  • Black smoke from the exhaust, caused by incorrect fuelling

  • Turbo lag or overboost, if MAP signal is used in boost control strategy

  • Engine stalling or failure to start, especially on turbocharged petrols

Fitting Tips

  1. Inspect intake hoses and connections for leaks or splits before fitting a new sensor

  2. Check and clean the sensor port if carbon buildup is visible

  3. Ensure connectors are secure and corrosion-free before installation

  4. Clear stored fault codes and verify live pressure readings after fitting

  5. Avoid overtightening, especially with plastic housings — use OE torque specs
