MAP Sensor

 

MAP Sensor

The Manifold Absolute Pressure Sensor (MAP) is a component of the engine management system as used in many modern internal combustion engines. The MAP sensor creates a variable electrical output signal based on intake manifold vacuum. The Power Train Control module (PCM) uses the MAP sensor signal as an input to compute engine load and to optimize PCM outputs for fuel control, ignition and emissions.

What is a MAP Sensor and how does it work

How Does it Work?

  • Measures the amount of vacuum in the intake manifold
  • Power-train control (PTC) module uses measurement to determine engine load
  • PTC then delivers fuel to support complete combustion and clean emmissions

How is it Made?

  • Extensive use of robotics for precision assembly
  • 100% product in-line and end-of-line inspection from raw material to packaging of finished product

Why Does it Fail?

  • Moisture entering the sensor when the engine is off
  • Heat exposure
  • Normal wear of the sensor element

What are the Symptoms of Failure?

  • Check engine light comes on
  • Engine may have a rich or lean fuel mixture
  • Rough-running engine, hesitation or misfire

What are the Implications of Failure?

  • Engine performance will suffer
  • Increased emissions, harming the environment

How Difficult is the Install?
