    Where to find the cause ?, because this error does not always pop up, but if it pops up, you can not start the engine.

    Hello, here you have a bit more information.
    P0606 Processor of the engine control unit / drive mechanism
    Check the following components:
    Engine control unit Perform all diagnostic steps
    1: Check the plug connection.
    Measure the resistance between pins a 29 (E2 ABS control unit). Is it less than 1 ??
    2: Check the connection on the plug.
    Measure the resistance between pins and 25 (E2 ABS control unit). Is it less than 1 ??
    3: Check the connection on the plug.
    Measure the resistance between pins and 30 (E2 ABS control unit). Is it less than 1 ??
    P0606 The engine does not start; The engine warning light is on

    The engine does not start; The engine warning light is on

    Symptom
    The engine does not start
    The engine warning light is on
    Engine control unit:
    Fault code: P0606
    Cause
    Defective injection pump PSG16
    Solutions
    Injection pump control unit:
    Check the power supply
    Check and clean the ground points

    If there is no fault
    Replace the PSG16 fuel injection pump
    Initialize the immobilizer assembly
    Use the diagnostic tool for this operation

    And about which of these DTCs are we writing?


    P0606
    Electronic control unit (ECU) - fault

    o The control module recognizes a fault in the current circuit by an internal analytical logic.

    P0606
    Internal error in communication of the control unit

    o The control module recognizes a fault in the current circuit by an internal analytical logic.

    P0606
    Re-initialization of the control module

    o The control module recognizes a fault in the current circuit by an internal analytical logic.

    Tip:

    The fault code can also be entered if the voltage supply at the ECM terminal is incorrect: 49, 51, 53, 55 (X93).


    Added after 3 [minutes]:

    If for the latter P0606-re-initialization of the ECM, this tip is very useful, especially when looking at the yearbook :D :D :D

Topic summary

The discussion revolves around the P0606 error code in a 2003 Opel Zafira 2.0 DTI, which indicates an issue with the engine control unit (ECU). The user experiences intermittent engine start problems, with the error preventing the engine from starting. Various diagnostic steps are suggested, including checking the plug connections and measuring resistance at specific pins related to the ABS control unit. Potential causes include a defective injection pump (PSG16) and issues with the ECU's power supply. The conversation highlights the importance of proper connections and the possibility of re-initializing the control module. A faulty solenoid valve from a different vehicle model is also mentioned as a potential contributor to the problem. Ultimately, the user notes that replacing the solenoid valve resolved some issues, but starting difficulties on warm engines persisted.
