car won't start
Please help. My 2003 Mazda 6s 6 cylinder 5 speed with 68500 miles died while my daughter has driving it. I pulled the following codes; P0122, P0223, P2110, P0222, P2107, P2100. Car cranks and starts for a second or two then dies. I have read the codes but don't know where to start.( the car is stock)

You might have a timing fault or a wiring loom fault , I work on mazda vehicles in England we dont have the 6 - cylinder engine here but i might be able to help out , you will need to take the vehicle to a repair shop and have the timing inspected, also you might have a fault with the throttle body. check the timing first . It is known for the timing gears to come loose and cause non start faults. Let me know how you get along .

Before jumping on the timing chain, be advised that
P0122 = Throttle Position Sensor/Switch A Circuit Low Input
P0222 = Throttle/Pedal Position Sensor/Switch B Circuit Low Input
P0223 = Throttle/Pedal Position Sensor/Switch B Circuit High Input
Which suggests that is part of your problem at least.It would certainly explain why the engine will fire up for the first few seconds, and then as soon as it goes into closed loop idle speed control, the ECU gets rubbish for the throttle position and causes the engine to quit.
Check first that the TPS connector is clean and properly mated to the TPS sensor.
The TPS sensor should be supplied with 5V on the A terminal of the connector harness side with ignition ON, engine OFF. The B terminal should be at ground potential.
Now with the engine and ignition OFF, and looking at the sensor itself, the resistance measured between the C and B terminals should be near zero with the throttle closed, and move smoothly up to around 4000- 5000 ohms as the throttle is manually moved from closed to fully open.
Unfortunately, I don't have an OBD II fault code interpreter for P2100,P2107,and
P2110 as these may be 6 cyl. specific and my car is a 4 banger.
I would not be looking at the timing chain/belt issues because these are P002x codes and if applicable, would be associated with P03xx (ignition/misfire) issues as well.

got my 6 back
Well, the dealer said the ele. throttle body went bad. He said, it some times happens and you can't take it apart and fix anything, just replace it.
Also the dealer lightened my wallet by $630 Oh well, the wife is happy to have her car back.

I'm sure was just the throttle position sensor, and it is an replaceable part, though once installed, there is a little bit of aligning to throttle plate to do. Doing it yourself would have cost about $120.
