An automobile engineer must search the correct meaning of the C1422 Code and without using the correct meaning of the code, it is not possible to solve the car engine problem. Even he knows all meanings from different manufacturers are not also same thing. Do not use the general meaning of the code what is available online. This meaning of the code is not very helpful and you have nothing to do with the general meaning but if you like you can read the general meaning. Do not drive the car with the engine problem and you need to solve the problem sooner.
