    I am thinking the EGT sensors from both input and output need to be replaced. Any advices/suggestions? Greatly appreciated.
    Thank you

    Your first active code. This may be causing the other 3 sensor codes.
    P009B Fuel Pressure Relief Control Circuit/Open
    [​IMG]
    The PCM monitors the fuel pressure regulator and opens the fuel pressure relief valve to return excess fuel back to the fuel supply system. Code P009B is set by the PCM when the Fuel Pressure Relief Control Circuit is open. What is the severity of this DTC? The severity of this code is normally moderate based on the specific malfunction.

    Thank you for the reply. I have purchased all 3 sensors and plan to replace them first because they are cheaper and easier to install.
    Is P009B a common error code and whats your experience in dealing with it?

    I have attached the diagnosis images since previous links are broken.

    Thank you!
