Question about Cars & Trucks
Here is the list.
Code 440 and 441 are for a problem with the vent for the gas tank.
Code 456 is for a leak in the vent system for the tank.
The computer vents the gas tank to the vapor canister several times per hour while the engine is running.
Code 700 is a general fault with the transmission or the trans control module.
Code 562 is for low voltage which can involve the computer or the alternator or both.
The codes starting with 4 would probably not cause the engine to die.
The 700 code could point to a shift problem but again would probably not cause the engine to not start.
The 562 code would mean the electrical system is below 12 volts which could cause your symptoms, you would need to check battery voltage and the alternator output.
Some of this could be as simple as a bad connection at the battery or something as expensive as a faulty computer.
