1.Product Introduction Special integrated sensor for automobile intake manifold, simultaneously collects intake air pressure and temperature data, transmits unified signals to vehicle ECU for fuel injection and air-fuel ratio control. 2. Working Principle Built-in MEMS pressure chip and NTC thermistor. Pressure changes deform silicon diaphragm to output pressure signals; air temperature changes alter thermistor resistance to feedback temperature data, processed by integrated circuit for ECU calculation. 3.Common Technical Parameters Working pressure: 10~400kPa(range can be customized) Precision: ±1.25%VCC (0℃~100℃) Total error band: ±2%VCC (-40℃~0℃) ±1.75%VCC (100℃~140℃) Operating temperature: -40℃~140℃ Storage temperature: -40℃~140℃ Protection pressure: 800kPa Burst pressure: 1200kPa Electrical interface: TYC01-1718645-1 (customizable) Protection grade: meet IP65 standard according to GB4208-2008 Shell material: PBT+30%GF Supply voltage: 5±0.25VDC Output voltage: 0.5~4.5VDC (adjustable within 5V) Or Sent protocol output Output low clamp level: 8%VCC (customizable) Output high clamp level: 92%VCC (customizable) Supply current: 15mA (Max) Output response time: less than 10ms Overvoltage protection: 16VDC 5min Short circuit protection: Yes EMC(150khz ~ 2.5GHz): 50V/m EMC(80mhz ~ 3Ghzz): 100V/m ESD: 15KV 4.Product Structure MEMS pressure sensitive chip, NTC temperature probe, signal processing circuit, sealed plastic housing, automotive plug connector 5.Core Functions Real-time intake pressure monitoring Intake air temperature detection Accurate air-fuel ratio matching Engine fuel injection adjustment Idle and acceleration performance optimization 6.Typical Fault Performance Unstable engine idle speed Weak vehicle acceleration Increased fuel consumption Engine fault indicator light on 7.Application Scope Gasoline passenger vehicles, commercial vehicles, motorcycle engines, small general-purpose engines
