Air charge sensor for E39, E46, Z3 Brand: ES#: 4475884 Mfg#: 13621432356 Qty: Availability: Back Ordered Mass Air Flow Sensor (MAF) 03/2003 and later E46 use the 6 pin MAF connector. The MS45 ECM gets the Intake Air temperature from the MAF, ergo the additional wiring and different connector, the earlier MS42-43 ECM uses a temp sensor in the intake manifold.

Just got done clean'n my MAF sensor. It's around that time for service when they change ur. air filter and oil. And with my N55 I'm rocking Harold's foam filter. so i don't need a new filter just need to clean it and recharge. A bad mass airflow sensor can leave your Toyota Tacoma’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Tacoma’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion Since the MAF sensor is responsible for measuring air flow into the engine, they have a lot of air passing through them. In fact, more than 9000 liters of air can flow through the engine for every liter of fuel used. That’s a lot of air! And with that comes the potential for a lot of contamination. Dust, dirt and other debris can all get into The most common signs of bad mass air flow sensor (MAF) in Hyundai Sonata are loss of power or slow acceleration, engine hesitation or jerking during acceleration, erratic idling, misfires, poor exhaust emission values and sometimes black smoke comes out of the tailpipe. The mass air flow sensor is part of the engine’s intake system and is A wire stretched across the sensor’s flow tube is heated to 3,920° F (2,000° C). The amount of electrical power required to keep this wire at 3,920° is translated into a DC-voltage signal return that rises proportionately with engine speed (see Figures 1 and 2 , which show voltage readings at 772 rpm and 1,700 rpm, respectively) and is Mounted in the air intake duct or air filter housing, a sensor detects the air density as it heads into the engine intake to be mixed with fuel. Common mass air flow sensors use a heated platinum wire in the sensor that records an electrical resistance value in the car’s engine control module. As more air is drawn into the engine, the airflow RPMUXRL.
