What Is Fuel Trim - Web learn what fuel trims are and how they adjust the amount of fuel injected in the engine to keep the air/fuel ratio close to 14.7:1. Web learn how to use obd ii generic scan tool to monitor and record fuel trim data in different engine loads and analyze it to solve driveability issues. Small errors in this cylinder air/fuel mass estimations are expected but larger errors are an indication of trouble. Volkswagen calls fuel trim “oxygen sensor adaptation,” and ford classifies fuel trim as a “continuous monitor” that runs when the fuel control. See examples, diagrams and tips for diagnosing engine problems and fault codes with fuel trims. Fuel trim data can help you identify the root cause of p0171 and p0174 codes and avoid common misdiagnoses.
