Start with the throttle sensor on the gas pedal, check with voltmeter one wire should have 5.0 volts one of the other should get more voltage as you press the gas pedal.

The 0506 code is an information code that says the idle speed is lower than expected, the problem code is the 2112 start here, this code refers to the throttle body not operating smoothly, you can remove it and clean it, check for smooth operation and check the TPS at the same time, if you cannot get a smooth operation you will need to replace the throttle body assembly, reset the check engine light and verify your repair. Hope this helps, let me know

When it comes to the air bags and the air bag system you really should take it to a professional to have it looked at. Don't try and diagnose yourself for you could cause the air bag to fire off.

05 corolla, after gassing up, whether partial or full fillup, car is hard to start. will crank but runs rough before going dead. after 3-4 starts and runs fine. toyota dealer checked codes; po 171 system...


Sounds like you may have an issue with the check valve on your in tank fuel pump. When these go bad, you have to crank several time to build up enough pressure in the fuel rail for engine start. With a good check valve, the fuel pressure will not bleed off and the pressure is retained for the next engine start.

Check engine light on


P0700 - Transmission Control System Malfunction, this is a transmission or PCM issue and needs further diagnosis with other test gear.

The P1684 code simply means that the battery has been disconneted within the last 50 engine starts.
