Hi Experts.
i am getting P0456 & P0406 Error code.
can some one please tell me what possible part do it need ?
thanks

 

P0406 is the EGR temperature sensor.

P0456 is a vacuum leak in the gas tank's EVAP system. There are a lot of possible causes for this code but the 2 most common are a loose or bad gas cap and the EVAP canister vent control valve.

See pages 331 and 398 for code descriptions and troubleshooting.

You neglected to say what year your car is

 

thanx for the prompt reply.
it turns out to be one of my electrical fuse went off and autozone gave me code which was stored on their scanner.
fuse was fixed and replaced the break switch for my shift lock .
car drive perfect.
