Hello,

I'm Shantal and I'm a moderator for this topic.

I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I was checking to see if you had already found your answer or if you still need assistance from one of the Professionals.

Please let me know if you wish to continue waiting or if you would like for us to close your question?

Thank you,

Shantal

Hi there, this code is for pressure being higher than the target value.

 

Now this could be caused by a couple of things including the fuel pressure sensor itself.

 

The place to start would be by having the actual fuel pressure checked to see if it's within specifications or not, if it is and still throwing the code then the sensor itself is bad. If the pressure is off then it's likely the result of a faulty suction control valve on the pressure pump.

 

Let me know if you need anything else.
