Hi. Thanks for using JA! I will try and help you out.
The 164-11 code is defined as an injection actuation pressure system fault. This basically means the high pressure system is having trouble making the required pressure.
For example. The ECM may want 2000 psi actuation pressure but the IAP sensor is detecting only 1500.
There are several things that can cause this code.
The first and most common is a faulty IAPCV. Injection Actuation Pressure Control Valve. Inhae replaced hundreds of these for this problem.
Second is a faulty high pressure pump.
Third is a faulty IAP sensor.
And lastly is a leaking injector.
Please reply back if you need more help or have more questions. I am happy to assist.
