SOURCE: speedometer and tachometer stopped working

If the speedo isn't working properly, the first thing to check is the output speed sensor wires on the rear right side (near the bar code) of the tranny case. Follow the wires and make sure it hasn't been cut, pinched or shorted.
If all is well there, take the output speed sensor off. Watch out cause you'll get wet with tranny fluid (Dexron 6). (Be ready to plug it up.) If there are no metal chips or debris on the magnet inside, check it with an ohmeter on the two pins to see what the reading is. It should be around 6 to 10 ohms. If it's not steady, get a new one. Make sure the pins are clean on the connectors.
Apply some white or build grease around the shaft and "O" ring and re-install. Don't overtighten. The bolt is a "tap-tite" and should need only about 5 or 6 ft/lbs torque. (Run it in and give the bolt a quarter turn.)

SOURCE: code came back as iat sensor reading high

IAT stands for Air Intake Temperature Sensor and it is located in the intake tube coming from the air filter box tot he engine. Easiest way to find it is look at the top of your engine where it says 2200. Coming right out of that manifold is a black ribbed tube about the size of a baseball to softball. It should be going towards the direction on the front drivers side. on the back side of that tube, about 4 inches away from the intake manifold (the things that says 2200) is a plug with wires. That is your IAT Sensor. If it is unplugged, plug it back in. Otherwise unplug it and replace it. Make sure to disconnect the battery while you do this so the computer resets itself after the new one is installed. Thanks and please don't forget to rate!

    Where is the MAF on a 2000 Pontiac Sunfire?

    MAF will be located in the throttle body I believe. Screwed to the top of the throttle body where it hangs down into the airway as air enters the intake. Not 100% on that car but it will be in that area. Hope that helps.

    1999 pontiac sunfire sits in pouring rain then sputters and check engine light flashes

    You definitely have a faulty MAF (mass air flow) sensor. The MAF controls the idle of the car that when it's faulty an erratic idle may occur. You may even end up stalling during take off so have the MAF replaced. It is located on the throttle body.

    Where is the timing belt/chain located on a 2003 Pontiac Sunfire, also where is the water pump, valves and t sensors, located in the car as wekk thanks.

    I recommend you get the Haynes repair manual on your vehicle for all of these. That will tell you not only where they are but how to check, adjust or replace them if needed. The timing belt is normally located on the front of the motor under a cover, the vales are located under the valve covers on each side of the motor, or top of the motor in a 4 cylinder, and the temp sensor location will depend on which engine you actually have installed in the vehicle.

    2003 pontiac sunfire GT

    When they say "bank," they're referring to cylinder banks 1 or 2. Bank 1 is the passenger's side and has cylinders 1-4 on it. Bank 2 is the driver's side and has cylinders 5-8 on it.

    P0171/0174 indicates that the long term fuel trims have reached a maximum (should be somewhere around 30-35%). Fuel trims are how much fuel the PCM adds or subtracts. 0171/0174 indicates that the engine is running lean, meaning that outside air is getting past the mass air sensor. The O2 sensors see this excess air and the PCM responds by cranking up fuel trims to add more fuel for that more air.

    Possible solutions include:
    • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
    • Inspect all vacuum and PCV hoses, replace if necessary
    • Check for a dirty fuel filter and proper fuel pressure
