This error code, ECU 000656.13, is triggered when the ECU detects that an incorrect QR Code was calibrated into the ECU for the electronic injector in cylinder no. 6. Incorrect QR Codes can lead to improper injector calibration, resulting in inefficient fuel delivery and suboptimal engine performance.

Error code ECU 000656.07 indicates that the ECU has detected a mechanical failure in the electronic injector for cylinder no. 6. This is identified by the lack of a drop in fuel rail pressure during the injection process, suggesting that the injector is not delivering fuel as expected. Mechanical issues can arise from blockages, internal…

Error code ECU 000656.06 is set when the ECU detects a short circuit in the electronic injector circuit for cylinder no. 6, resulting in resistance that is too low. This condition typically indicates a short to ground, which can cause the injector to malfunction, leading to misfires, inconsistent fuel delivery, and potential damage to the…

This error code, ECU 000656.05, is generated when the ECU detects an open circuit in the electronic injector for cylinder no. 6, indicating that the circuit resistance is too high. This condition can prevent the injector from delivering fuel to the cylinder, leading to misfires, reduced engine power, and potential engine damage due to improper…

Error code ECU 000656.02 is triggered when the ECU detects that the part number of the injector installed or calibrated in cylinder no. 6 is incorrect. This can lead to improper fuel delivery, misfires, reduced engine efficiency, and potential damage to the engine due to mismatched injector characteristics.
