Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
Did you have any codes? Most cases when the car goes into limp mode it's not the transmission. So if you have any past codes you can share with me as to why the valve body what changed, let me know. Also did he reprogram the new valve body?
What codes did you have though? Did you have any?
What was that code the transmission guy found?
I can speak with you, but you would need to accept the premium service. It is a additional charge to speak to me. But I am sure after you speak with me we may have a idea what is going on.
I can think of a few things.. First is the App sensor which is the electronic gas pedal has a 5 volt reference. If something interrupts the 5 volt reference the car will go into limp mode. Now the Ac pressure sensor and the evap pressure sensor also share the 5 volt reference. So if one of the two sensors interrupts the 5 volt reference, then the car will be in limp mode. Also if the engine fans come on when in limp mode, that would indicate a communication issue with a major control unit. This is why I would like to know what code the transmission guy found. That would help me determine which direction we need to go.
