I have a CODE 3419 and 1022....if anyone has an idea what it may be....I appreciate it.
1022 is water in fuel and the operator will get an associated water in fuel graphic symbol and alarm on the instrument cluster when the condition is active (not historic) 3419 is similar to the 3405 you asked about a couple of weeks ago, except the condition is short to ground instead of open circuit on the turbo pressure control valve. A few questions for you : Are these codes active on the vehicle, or are you reading historic information from the fault log? How did you come out previously with the 3405 code resolution? Is this the same vehicle as a couple of weeks ago? Do you have a service manual? If not, it would be a wise investment.
