Product type
A MAP (Manifold Absolute Pressure) sensor is an essential component in modern automotive engines, designed to measure the pressure within the intake manifold. This sensor provides critical data to the engine control unit (ECU) to optimize fuel injection and ignition timing for improved engine performance and efficiency. Typically made from durable materials such as plastic and metal, the MAP sensor is built to withstand harsh engine environments.
| Operating Voltage | 5V to 12V |
| Pressure Range | 0 to 2.5 bar |
| Output Signal Type | Analog or digital |
| Temperature Range | -40°C to 125°C |
| Connector Type | Various automotive connectors |
When selecting a MAP sensor, consider the specific requirements of your vehicle's engine management system, including the operating voltage and output signal type. It's also important to check compatibility with your vehicle's make and model. Buyers should specify the pressure range and temperature tolerance needed for their application, as well as any necessary certifications or standards that may apply.
