P0101


Here is the definition of the code.

P0101 GMC Description The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).

The temperature of the hot film is controlled by the ECM acertain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change.
Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection

I need step by step instructions on using Casio fx-115ES ee or exp burron.


The equivalent of the EE or EXP button on the Casio Fx-115ES is marked as x10^X. It is located at the bottom right of the key pad left of the = key.
To enter the power of 10 in a number written in scientific notation, you press the x10^X button followed by the exponent. If the exponent is negative you press the change sign key first [(-)] , then the one or 2 digits in the exponent.
Example Enter the mass of the proton m_p in kilograms
1.6726217 [x10^X] [(-)]27 [=]
In grams the value above is multiplied by 1000.
or
1.6726217 [x10^X] [(-)]24 [=]

Since the calculator has the physical constants (the FX-991ES definititely has them)
  1. Display the proton mass in kilograms
  2. [SHIFT ][7] to open the constants catalog,
  3. type 01 for the proton mass, then press the [x^-1].
  4. Divide the result by 1000
  5. You should get 5.978638635 x10^23

How to convert mass(kg) of fuel product to Litres


To convert mass to volume(which litres is a unit for), you'll need the fuel's density. The units for the quantity is mass/volume, often kg/m³ or similar. To get the volume, divide the mass by the density: kg/(kg/m³)=m³. Since 1000 litres is equivalent to 1 m³, you'll need to multiply by a thousand to get the answer in litres.

How to calculate 24k gold in kilo grams now?


There is some confusion here concerning the two uses of karat. For diamonds and precious stones the karat is a measure of mass (weight) equal to 200 milligrams (or 0.2 grams). In the context of gold alloys, the karat is a measure of purity. Pure gold is 24 kt, 18 karat is 0.75 pure or 75 % pure gold and 25 % other metals (copper or something else), The most prevalent type of gold in North America is 14 kt gold, which is 58.333 % pure gold and the remainder (41.66%) other metals.
To get to back to your question, you cannot relate the purity of gold piece to its mass (weight) because all it says is that the piece of gold is close to 100% pure.

Does a 1996 Ford Taurus 3.0 have a hot wire type mass air flow sensor or a vane type? Would spraying carb cleaner into the MAF fix the problem of hard cold engine start? Once the engine warms up does the...


TheMobilian, Yes, the Mass Air Flow is a Hot Wire type. There is a spray made for the mass called mas air flow cleaner. Regular cab cleaner is too harsh and can eat the coating inside mass air flow and it's delicate parts. Use throttle bore foam cleaner; it works like bathroom scrubbing bubbles and eats the gum and varnish. When engine warms up (closed Loop) both sensors work together giving input to ecm for output. Have someone with a live data reader read both sensors. (Let me know the readings?)


Image Mass Air Flow(MAF)Sensor

PURPOSE

The Mas s Air flow (MAT) sensor measure s the amount of air flowing into the engine.

This value is used by the Powertrain Control Module (PCM) in calculating the required

Fuel injector pulse within order to provide the desired air fuel ratio. This input can also

be used in determining Electronic Pressure Control (EPC). Shift and torque converter

clutch scheduling.

CONSTRUCTION

The MAE sensor is located directly in the airflow path between the air cleaner housing

and the throttle body. Ail air entering the intake manifold must pass through the sensor.

Located in the MAT sensor directly in the airstream are two platinum wires, a hot wire

heated by electrical current and a cold reference wire. The MAF sensor uses the air flow

across these wires to calculate its output.

OPERATION

The hot wire is maintained at 200CC (392CF) above ambient temperature as measured by

a constant cold *e. The current required to maintain the temperature of the hot wire is

proportional to the air mass flow. The MAE sensor then measures the amount of

electrical current required to maintain this temperature difference and converts this

value to an analog DC voltage. This output varies directly with the mass air flow rate.



Pay attention to the Paragraph about the torq converter.

My 2005 ford explorer has acceleration problems


You may have a problem with your MAP sensor. The Manifold Absolute Pressure (MAP) sensor signal is electrically used in a similar way to the use of Mass Air Flow (MAF) sensor signal (although internally it is built differently). It takes a 5 volt signal from the computer, and returns a lower direct current signal in accordance with the vacuum in the engine. A higher output voltage means lower engine vacuum (which means more air flow is occurring), which is then calculated as “more fuel is needed”. Lower output signal indicates higher engine vacuum (which means lower air flow), which requires less fuel. 
It's not just fuel control though. The MAP sensor signal gives the computer a dynamic indication of engine load. The computer then uses this data to control not only fuel injection, but also gear shift and cylinder ignition timing. In some cases it is even used to calculate changes in barometric pressure, to automatically adjust for different altitudes.

The Mass Air Flow (MAF) sensor helps the computer to calculate the flow and mass of the air entering the engine. It does that by measuring the cooling effect of air flow over a heated wire element. The electronic circuit inside the sensor attempts to keep the sensor at a fixed temp.
When it is cooled more by an increased air flow, more current is needed to maintain a constant temperature. The increase in current is converted into a signal to the computer. In most cars this signal would be a high frequency signal. Not as high as a radio wave, but much faster changing than the (relatively) slow frequency of the Oxygen sensor.
During low air flow rates, such as at engine idle, the MAF sensor produces a lower frequency signal. During high air flow rates, such as at wide open throttle-road load, the MAF sensor increases the frequency. The control module then converts these frequencies into their corresponding Grams-Per-Second values.

The MAP or Manifold Absolute Pressure Sensor is a little though expensive device installed in your air intake hose or piping, or installed on the firewall and connected to the manifold with a thin hose. It has 5 or 12 Volts coming in, and it simply senses the vacuum in the manifold and attenuates (reduces, weakens) this incoming voltage by a certain factor. In other words it reduces the voltage in the range of 15% to 60% of the supply voltage (depending on the car's design these numbers will vary), and this varying (but non-pulsing) signal goes to the computer. Too much attenuation kills the engine, it will simply shut off. Yet if you control it correctly you can lean down the mixture from the stoichiometric (a big word that simply means “balance of ingredients”) which is factory set at 14.7:1 (14.7 parts of air to 1 part gasoline) – down to 20:1, maybe even 50:1 or 100:1.
Good luck and hope this helps, in short: you may have a bad MAP sensor and may needs to be replaced.

My vehicle just shuts off while im diving, it pulled codes p0453


They might be refering to the MAP Sensor. A manifold absolute pressure sensor (MAP) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU). This is necessary to calculate air density and determine the engine's air mass flow rate, which in turn is used to calculate the appropriate fuel flow. (See stoichiometry.)
An engine control system that uses manifold absolute pressure to calculate air mass uses the speed-density method. Engine speed (RPM) and air temperature are also necessary to complete the speed-density calculation. Not all fuel-injected engines use a MAP sensor to infer mass air flow; some use a MAF (mass air flow) sensor. Several makes use the MAP sensor in OBD II applications to test the EGR valve for functionality. Most notably General Motors uses this approach.
Contents How the MAP value is used The manifold absolute pressure measurement is used to meter fuel. The amount of fuel required is directly related to the mass of air entering the engine. (See stoichiometric.) The mass of air is proportional to the air density, which is proportional to the absolute pressure and inversely proportional to the absolute temperature. (See ideal gas law.) Engine speed determines the frequency, or rate, at which air mass is leaving the intake manifold and entering the cylinders.
(Engine Mass Airflow Rate) ˜ RPM × (Air Density) or equivalently (Engine Mass Airflow Rate) ˜ RPM × MAP / (absolute temperature) They could also be refering to the fuel pressure sensor. If so, then yes this also can cause the problem. You shoud have your fuel pressure checked for about $34.00. If you have a bad fuel pressure regulator you will need to change it out. If it remains undelt with then it could take out your fuel pump. Most fuel pumps are located and installed in the top of your fuel tank and are submerged into your tank. It needs the fuel to keep it cool, but if you continually keep your fuel under 1/4 of a tank you will drastically reduce the life of your fuel pump. Fuel pumps can be expensive to replace. I replaced my wifes in her 1997 Chevy Blazer and it cost me $350.00 (lifetime warrenty). If you keep your gas under a 1/4 of a tank most of the time and your pump is found to b bad then you need to opt for the LIFETIME replacement pump. You only want to have to pay for the pump once, believe me. Otherwise you really haven't provided enough of the symptoms to go on. Does it shut off when you are at speed, or stall when at a stop? If it stalls when you come to a stop you could have bad Oxygen sensor(s). If it's the oxygen sensor(s) then you should replace all of them.

These are merely suggestions.
Good Luck!
