The check engine soon light is on, when I checked the code, p1614 and p0406. How would I fix the code. The check engine light is orange.

Answer 1

P1614

"This code is usually triggered when a not registered or damaged key is used to start the engine. When the starting operation is carried out five or more times consecutively with the same unregistered key, the system will lock.

 

If the problem occurs try disconnecting the car battery for about 30 minutes and then try starting the engine with a known registered key. If the problem persist you have to have the dealer erase the code and reprogram the keys again."

P0406 

The EGR valve may need to be cleaned or replaced since carbon built up will clogg the EGR and set the code on
