Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.
I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.
Dear customer, the error code that you are presenting is referring to the pressure that the transmission fluid is presenting, I imagine that when you told me that you have replaced the fluid and the filter you are talking directly about the transmission.
The problem is that this signal is given by a sensor that simply measures the amount of fluid pressure, when the fluid is below the normal operating parameters it activates this error code, therefore it is very likely that the code is due to the fact that the sensor is faulty detecting incorrect values and parameters, this is normal for this sensor to be found in the transmission valve body and it tends to damage over time.
Do you understand me, dear customer?
My goal is to give you the best advise i can, therefore please do not doubt to ask if you have any doubt or if there is anything else i can help you with.
Kind regards, Sebastian.
