Performing a volumetric efficiency test can reveal the accuracy of a vehicle's Mass Airflow Sensor (MAF) as well as potential issues with the engine and can be the key to successfully diagnosing and fixing a vehicle. A failed MAP sensor has serious implications on fuel control, vehicle tailpipe emissions and fuel economy. So now my question. MAP Sensor is not your problem Matt. The ECM uses MAP sensor data to run crucial calculations, such as engine load, fuel injector pulse, and spark advance. I dont care that it says i have no boost when i can tell i do. I chased what I thought was a MAP sensor problem, changed it out and found essentially no difference in KOEO readings from the original. As it has a critical role to play in the engine's working, therefore it is equally important to follow its maintenance tips.However, sometimes due to the Faulty Manifold Pressure Sensor, the fuel . There is a daily variance based off of the weather (high and low pressure systems). On modern diesels less boost means less NOx, more soot, more fuel economy, and last but not least more 'pedal lag'. The turbocharger boost sensor provides accurate readings back to the ECM to ensure the engine is functioning correctly. Spring scale reading should be 10 lbs. At KOEO, the sensor would read atmospheric, and SLOWLY increase as pressure built in the intake, and SLOWLY decrease when it dropped. It is located on the intake runner on the 01 engines, but is in the neck of the bridge on 02-04 engines. I prefer a 15 psi gauge when working with most 6.5's and the stock turbo. Applications using a turbo or supercharger may have a 2- or 3-bar MAP sensor. The sensor's function is to measure the amount of air passing through the intake system and into the engine. Erratic RPM and MAP sensor readings normally indicate an internal misfire condition due to improper sealing of the cylinder. But I happened to notice that the MAP sensor wasn't varying much. blue might be right, or they might drop it to prevent overboost codes or keeping the wastegate closed longer or... or... maybe some of the tuner guys might weigh in on this... A forum community dedicated to all Ford Diesel owners and enthusiasts. Engines that use a MAP sensor are typically fuel injected. Barometric pressure is measured in millibars. John Wood's valve body.
