Description:

Error code ECU 000651.02 is triggered when the ECU detects that the part number of the injector installed or calibrated in cylinder no. 1 is incorrect. This discrepancy can lead to improper fuel delivery and engine performance issues.

Reaction:

The ECU may adjust engine parameters or limit performance to prevent potential damage due to incorrect injector calibration.

Recommendations:

• Verify Injector Part Number: Check the part number of the injector installed in cylinder no. 1 and ensure it matches the specified part number for the engine.
• Recalibrate Injector if Necessary: If the part number is correct but the issue persists, recalibrate the injector to ensure proper operation.
• Replace Incorrect Injector: If the injector part number is incorrect, replace it with the correct one.
• Reset ECU and Verify Operation: After making corrections, reset the ECU and perform tests to ensure that the injector is operating correctly and no further errors are detected.

Note:

Using the correct injector part number and proper calibration are essential for maintaining optimal engine performance and fuel efficiency.
