The storage of a P1101 trouble code happens when the Powertrain Control Module (PCM) detects a fault within the Mass Air Flow (MAF) sensor system. Related codes that the PCM might store along with a P1101 trouble code includes a P1001, P1100, P1102, P1103, P1104, and P1105 code. What the P1101 code mean Step by step guide on how an automotive mass air flow sensor (MAF) works. Step 1 - The mass air flow sensor is designed to monitor the volume of air passing into the engine at any giving time (located in the intake tube connected to the throttle body) this information is then transmitted to the computer for calculations while helping adjust fuel injector input and ignition timing settings The mass air flow sensor measures the air mass flowing into the engine intake. Measuring air mass is critical in calculating how much fuel to add to achieve the correct air-fuel ratio (AFR). The ideal AFR is 14.7:1 (14.7 pounds of air to 1.0 pounds of gasoline), but real-world AFR varies
Q: If you unplug the mass air flow sensor the car will start. If you try to plug it in while it's running the car will die. My car has 90000 miles. My car has an automatic transmission. This is a sure sign of a shorted mass.. When testing a digital air flow meter, the output signal must be correctly identified: these units often measure both air flow and intake air temperature and give each a digital output. At first glance, the digital air temperature signal is similar to the air flow signal; however, the former is often a pulse-width modulated (PWM) waveform with.

The Mass Air Flow Sensor is located on the left side of the engine compartment, attached to the air cleaner housing its combined has more than two wires off it. most of fuelling on that system is based on the closed circuit wide band 02 sensors added to that sensor rarely do they go faulty more chance of 02 sensors being the problem or the breather pipe from the top of rocker cover is cracked where cant see it, only way to be sure is smoke test the inlet manifold or remove the breather and check it for.
Before air mass meters we had air flow meters (on my '84) which are electronic equivalents of the old mechanical types of fuel injection control. They are less comprehensive in their evaluation of the air that the engine is using. Air flow meters use a wiper that crosses a grid of resistance traces on a printed circuit board All good suggestions. If the MAF is dirty would a good cleaning with some CRC Mass Air Flow cleaner be of any benefit? If the air filter is passing a little because of a poor seal this can crud up the MAF. I used the CRC about every 4 month on my gasser. But it was used a lot offroad. It made the difference. CRC Sensor Kleen is cheap and it works Service Mass Air Flow Sensor MAF Step 6 - Testing the exhaust system oxygen sensors can help determine the functionality of the sensor.
