Question about 2000 BMW 7 Series

Open Question

I need to find a wiring diagram for my 2000 BMW 740i.

I purchased a DVMotorsports performance chip, EP93, which connects to the Mass Air Flow Sensor. My wiring harness has 5 different colored wires which attach to the MAS, but only 2 of them are for the AIT which is needed to attach this part to.!!!! Is there anybody that can instruct me on how to find this information, or perhaps give me the colors of the two wires, since I've already spent about 6 hours looking thru search results and links that don';t take you where they say they will!

If you are installing a so called "chip" don't do it, it can harm the engine due the changes it causes in fuel control as related to Intake Air Temperature and burn holes in the pistons. All that little part really is, is a $.50 (50 cent) resistor that you can buy from Radio Shack, it is smoke and mirrors and it also will void any warranty you may have. I for one strongly advise against installing it, it will make not difference in power and all there claims are just lies and falsehoods..

I have a 2008 Pontiac G5 I was wanting to install a performance chip to it. It says to connect it to the IAT senor which has 5wires witch wires are for the IAT


The other three wires are for the Mass air flow sensor . That's a new one for me , performance chips or turners are used through the DLC . You program the engine computer . I have no idea what they can do from the intake air temp. sensor .The tan an lit blue wires are for the IAT sensor !

Where is iat sensor on 2006 toyota tacoma 4.ol 4door located ?


This is the 2001-2012 Toyota Tacoma wiring diagram, Toyota Tacoma IAT (Intake Air Temperature) Sensor Location and the Toyota Tacoma MAF (Mass Air Flow) Sensor Location, also included is a pinout of the sensor. You are likely installing a performance chip or a cold air intake kit for increased HP (Horsepower). You will want to be sure to disconnect the car battery before adding performance products.




Here is the Toyota Tacoma's Iat sensor diagram:

Po101 code


Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. Check for air leaks on or around any intake pipework using a good spraying of carb cleaner, if the engine surges then that's the leak. Check wiring to Maf and if the inside is dirty, again use carb cleaner liberally...NOTE: do not use Wd40... If the code comes back, it may be necessary to replaced the mass air flow sensor.

I have a 2000 VW GTI VR6.I'm trying to connect a performince chip


do not cut into these wires. any real performance programmer will not require you to do this. these ones that tell you to cut into the IAT will ruin a $700 mass air flow meter, and do not do anything. all they do is try to trick the computer into thinking it is colder then it actually is, and to richen the fuel mixture, which will actually HURT performance and emissions because the air density does not match what the temp sensor is reading. the temp sensor is there for a reason!

Mass Air Flow problem


The M.A.S. is in the top of the metal tube between the air filter box and the intake manifold. It will have a wire connected to it and it is held in by 2 screws. This is an easy replacement and should take no more than 5 to 10 minutes, assuming you are taking your time.
