Hi, I'm Wayne.

I'll be assisting you with this issue today.

Thank you for coming to Just Answer

Your Question is as important to us as it is to you

There should be a dash and more numbers.


The code is 6H 164 when the ignition key is turned on.

Thank You,

Give me a bit to pull this up.



Thank you for the response.

The 164 code is an Injection Actuation Pressure system code.

IT is the most common codes that are seen on the C7.

A faulty Injection Actuation Pressure sensor.

A weak High-pressure pump.

A leak at an injector.

I hope this helps you.
