However, here is a list of the most common fixes for the P2196 code. Replace oxygen sensor. Repair/replace wiring or connector. Replace mass air flow (MAF) sensor. Repair exhaust leak. Repair vacuum leak. Replace fuel injector. Replace the fuel pressure regulator. Update/replace ECM. Most modern vehicles with fuel injection do. The location of the MAP sensor is the intake manifold whereas the MAF sensor is usually located just before the air filter assembly. They measure 2 different parameters. The Manifold Absolute Pressure (MAP) sensor is used by the Powertrain Control Module (PCM) for engine load input.

FORD FIESTA MAF Mass Airflow Sensor Replacement MK7 ST MAF SENSOR Check out our Amazon store for the tools that we use in our videos: www.amazon.com UK/Ireland Location: Other/NonUK. Posted October 27, 2013. The Focus MK2/MK2.5 with 1.4 and 1.6 Duratec (Sigma) engine do not have an Idle Air Control (IAC) valve or Mass Air Flow (MAF) sensor. The amount of air going into the engine is calculated by the PCM using a Manifold Absolute Pressure (MAP) sensor which is mounted at the intake manifold. The MAF or mass airflow sensor measures the amount of air flowing into your engine and helps the computer to determine how much fuel to inject into the combu

The P2281 diagnostic trouble code is an indication of the existence of an air leak between the MAF sensor and the Throttle Body. The MAF sensor uses an electrical wire to make a determination as to the amount of air that is being permitted to enter the air intake system. This information is sent through this wire and delivered to the powertrain
In stock form, the R35 ECU measures airflow using a Mass Airflow (MAF) sensor located in the stock intake system. As modifications add up and increase power, the airflow can increase to the point that it exceeds the MAF sensor"s maximum capacity, preventing the ECU from accurately measuring air mass, and thus unable to deliver the appropriate
