Hello my name is ***** ***** thank you for your question.

This code is for a low coast brake solenoid valve function. Are you a repair shop? Do you have a scanner?

Expert:  Jay replied 3 months ago.

This type of codes requires advance diagnostics. This could be a electrical issue with in the transmission or a Mechanical. So tests with a scanner are done to actuate the solenoid to see if it show a response from the solenoid. If it's a electrical issue, the whole valve body would need to be replaced. If it's a mechanical issue, the transmission would need to be either replaced or over hauled. This is not a simple sensor type repair.

Do you have any more questions on this?
