http://thedodgegarage.com/turbo_pfi.html The 84-95 Dodge FWD cars (2.2/2.5/3.0) use a speed density system. The MAP MAP sensor is the primary sensor in determining how much fuel the engine needs. This is the second most important sensor to the ECU after the distributor's HEP(Hall Effect Pickup) sensor. Basically, the engine can flow a given amount of ...

I suspect the reason is for vehicles which operate "fly-by-wire" throttle pedals. Without a TPS, you'd have no idea how much throttle angle the drivers foot was asking for so the engine wouldn't know how far to open it's throttle flap.

While these two sensors are related to how the engine runs, their function and what they provide for engine management are completely different. MAP (or Manifold Absolute Pressure sensor) The MAP provides the computer with information as far as the density of the air. This tells the engine how much air is actually getting into the engine. This, along with ...

Surely there is a far simpler answer to this. Fuel in injected on the "suck" stroke, when the piston crown is traveling down the bore, thus effectively creating negative pressure in the combustion chamber. There is therefore no pressure to be pushed back into the injector. Yes the fuel is at a serious pressure, yes the injector is effectively a one-way ...

In cylinder pressure is in the 200 psi range. GDI fuel pressure is varied from 500 up to around 3000 psi. This alone is enough to keep fuel blow-back to a minimum. Carefully engineered injector pintle shape also helps. This is no different than port injectors. What is unusual is how the pintle is moved in a GDI injector. In the most successful designs the ...

I will try to answer this as best as possible. There are a few factors that come into play here (Mainly the manufacturer of said engine). Direct injection petrol engines work much like a diesel. You have a low pressure fuel pump that resides in the fuel tank itself, and a super high pressure pump that sits near the fuel rail that delivers fuel to the ...

How was the fluid level, do you have the proper amount of fluid in it? If so, then it sounds like it could be the torque converter, but I'd have a mechanic or transmission shop take a look and get their recommendation. Could be all you need is a drain and a refill with the proper fluid. Shaking at a red light could be worn or dirty plugs, the transmission, ...

The gas gauge is just an indicator and each vehicle is going to be different. I know the older Datsun Z cars had two gas gauges, one was the main one which showed the volume of gas down to 1/4 tank, while the secondary one showed from 1/4 down to empty. The secondary gas gauge was very accurate to give the driver a true indication of how much fuel was in the ...
