What are the sensors in a fuel injection system?
The electronics and Sensors diagram is typical wiring diagram for an EFI system. Some EFI systems may have more or fewer sensors than this drawing. This represents a typical fuel injection system. The engine and air temperature sensors are simple devices that change in resistance as the temperature changes.
Where does the ECM adjust the fuel injectors?
The ECM will adjust the fuel injectors pulse width accordingly. Note: Baro and MAP sensors look and work in a similar fashion, therefore only one of the two sensors will be found in one engine. Usually found either bolted on the intake manifold or linked with a vacuum pipe from the intake manifold.
Is the injector pressure sensor ICP for International?
ATTENTION: Due to storage or shipping, there would be very few tiny rust or scratch on the surface, and its color is not that bright (not beautiful appearance), it’s ok and will not affect its function, but if you care about its appearance, please do not place the order! We offer you this rather low price for only a limited time
What kind of sensor measures air flow in an engine?
Benjamin Jerew is an ASE-certified Master Automobile Technician with over a decade of experience in auto repair, maintenance, and diagnosis. In modern engines, the engine control module (ECM) measures or calculates air flow via either a mass air flow (MAF) or manifold absolute pressure (MAP) sensor.
What is part number for secondary air injection sensor?
• P2433: Secondary Air Injection System Air Flow/Pressure Bank 1 Sensor Circuit High VW has released an updated sensor kit and secondary air injection pressure hose (part # 07K 198 125) that is less prone to contamination. On 2005-2008 vehicles, the sensor can be serviced separately using part number 07K 906 051.

What causes 2.5L secondary air injection sensor code p2431?
On models with the 2.5 CBTA-CBUA engine, the hose for the secondary air injection system can be contaminated by foreign particles. The contamination can cause the following codes: • P2431: Secondary Air Injection Airflow/Pressure Bank 1 Sensor Circuit Range/Performance
When does the secondary air injection monitor run?
It should be noted that the secondary air injection monitor which checks for the performance of the air pump runs mainly when the engine is cold. Once the engine warms up the monitor is done checking the pump. With that said, it’s not the number of miles you drive that sets off the air injection monitor, rather the number of cold starts.
