P1103 code definition. The Powertrain Control Module (PCM) stores a P1103 trouble code when the voltage signal from the Mass Air Flow (MAF) sensor is higher than normal but still falls within the range specified by the manufacturer. In addition to a P1103 trouble code, other related codes the PCM might store include a P1100, P1101, P1102, and Aug 7, 2019 · Here are the most common symptoms of a bad or failing MAF sensor: Idle Issues – Your Navara may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. The exhaust color is usually darker when running rich. A lean condition is when there is Feb 10, 2007 · The MAF Sensor and O² Sensors work in conjunction with the DME in Closed Loop operation where the Air Mass measured (along with other variables like Engine Temp, Load, Speed, Fuel Quality, etc.) determines which Fuel/Timing MAP is selected. May 31, 2019 · This MAP sensor is mounted directly to the intake manifold, but others might be connected by a hose. Benji Jerew/Flickr/CC BY 2.0. The ECM uses MAP sensor data to run crucial calculations, such as engine load, fuel injector pulse, and spark advance. When at rest, the MAP sensor reads atmospheric pressure at sea level (29.93 in. Hg). Oct 31, 2023 · Symptoms of a bad mass air flow sensor are hesitation, surging, poor fuel economy, poor performance, black smoke, and difficulty starting the engine. Fault codes indicating misfires, and rich or lean air/fuel mixture are also common. And in some cases, the engine will often stall, and you will see a check engine light. May 4, 2023 · Yes it should. No it doesn't always. And when you do get that code it doesn't necessarily mean the maf is faulty. Hopefully if there was nothing wrong before it won't be too serious. It a could possibly be where sludge has accumulated around the fuel pump as well if sensor are clean. 2005 Ford Focus Mass Air Flow Sensor. 2005 Ford Focus Oxygen Sensor. 2005 Ford Focus Sensor - Power Steering Pressure. 2005 Ford Focus Throttle Position Sensor (TPS) jZDX.
