When you increase the diameter of the piping, you allow more air to flow over the 0-5 volt MAF sensor without overwhelming it with more air than it is designed to read through the change in electrical current as air passes over it. Also asked, what does a bigger MAF sensor do? This performance MAF sensor increases airflow by up to 45% and low-end torque. The performance mass airflow sensor replaces your OEM sensor and improves on mileage and can increase horsepower by 13. Just so, how much horsepower does a mass airflow sensor add? However, with additional sensors and inputs, an engine's ECU can determine the mass flow rate of intake air. Neither design employs technology that measures air mass directly. These are the vane meter and the hot wire. There are two common types of mass airflow sensors in use on automotive engines. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on.
Duramax lb7 mass air flow sensor problems code#
It still throwing the same code p0402 (egr valve) what else could it be. Be running E-zoil carbon crusher in fuel.
Duramax lb7 mass air flow sensor problems plus#
Plus mass air flow sensor, map sensor air cleaner and also had computer flashed and upgraded at the dealer. At Rock its 98.00 vs 220.00 and up.Can mass air flow sensor affect acceleration?Īs a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. Have a 2006 Silverado 2500hd 6.6 duramax.I changed the egr valve and cooler. There is a HUGE price difference though between OEM and aftermarket Hitachi. So a couple questions, does this sound like a MAFS issue? If so, has anyone used a the "HITACHI MAF0081" as opposed to the OEM or AC Delco? There is a Hitachi on it now which is OEM so I would imagine it would be the same. Its acting like that again but not from a dead stop and the cleaning doesn't seem to make much difference. I used Mass air cleaner and it seemed to fix things. beer festival london olympia bimini top parts diagram MEANINGS. The engine control module (ECM) uses the MAF sensor signal to provide the correct fuel delivery for all engine speeds and loads. The MAF sensor is an air flow meter that measures the amount of air entering the engine. P0103: Mass Air Flow (MAF) Sensor Circuit High Input. The mass air flow (MAF) sensor is integrated with the intake air temperature (IAT) sensor. P0102: Mass Air Flow (MAF) Sensor Circuit Low Input.
sensor problem Sensor Input Voltage High 28 Air Inlet or Intake Air. The code P0101 means that the signal from the mass air flow sensor (MAF) is. P0101: Mass Air Flow (MAF) Sensor Circuit Range/Performance Problem. Gold And Black Finish Ambient Air Temp Sensor Location 2014 Freightliner M2 - iATN. P0122 Throttle/Petal Position Sensor/Switch A Circuit Low Input. P0121 Throttle/Petal Position Sensor/Switch A Circuit Range/Performance Problem. P0120 Throttle/Petal Position Sensor/Switch A Circuit Malfunction. P0119 Engine Coolant Temperature Circuit Intermittent.
So i'm thinking maybe a MAFS? I know it got a lilttle "oiled" / dirty a while back when I installed a new S&B air filter where it was actually stumbling a bit when you first accelerated. 5L Diesel Engine Duramax First Generation: 2001-2004 (LB7) Duramax Second. The mass air flow (MAF) sensor is integrated with the intake air temperature (IAT) sensor. P0118 Engine Coolant Temperature Circuit High Input. But from a roll there is a significant lag before it takes off, then it pulls pretty hard as well. Just did head gaskets, injectors, opened up turbo inlet and LMM exha manifold on an 02 LB7 and the throttle seems to be a little flat from any significant roll.
