At least here in the states, it tends to be around $120-150 IIRC. 03-25-2014, 09:36 AM #6. MarcoZandrini. Member. A Break In the Circuit. Your MAF sensor receives power and sends data to the ECU (engine control unit). A break or damage to the wiring harness can cause voltage loss. That, of course, causes your engine computer to log the P0102 code. Make sure to check the connector as well, since it can sometimes deteriorate to a point where pins no longer How to troubleshoot a MAF sensor – a technician’s checklist. 1. Check the connector for a correct fit and good contact. 2. Check the mass air flow sensor for damage. 3. Check the measuring elements for damage. 4. Check the voltage supply with the ignition switched on (circuit diagram for pin assignment is necessary). What makes you think your problem is the MAF sensor? You tried cleaning it I assume? Save E e46CrispOne Discussion starter 2 posts · Joined 2012 #14 · Jan 25, 2013 Well I took it to a reputable german auto service place around town, (not a BMW dealer though), and he read my codes and it pointed to the MAF. The M56 SULEV uses Siemens MS 45.1 engine management and includes many emission control system changes. The emission relevant components are warranted for 15 years or 150,000 miles. M56 B25 engine power output and performance is the same as the comparable models with the M54 B25 engine. I am wondering if the MAF sensor would cause the transmission light to come on. My car is a 2004 n42 engine. Would low trans oil level throw these codes. I'm very confused. Any help would be greatly appreciated.

On its intake stroke, each cylinder draws in a volume of air approximately equal to cylinder displacement, so in two revolutions of the crankshaft, your 2.5L engine will "intake" ~ that volume of air, 2.5 liters, and my 328 will draw in ~ 3.0 liters of air. The MAF (MASS Air Flow) Sensor is dealing with Mass, NOT Volume, but the same principle Vay Tiền Trả Góp Theo Tháng Chỉ Cần Cmnd Hỗ Trợ Nợ Xấu.
