Some Infiniti QX60 owners report experiencing issues related to the C1130 and P01P01 diagnostic trouble codes, which may indicate problems with engine signal communication and output signals from the ECM. The C1130 code specifically points to a failure in the ABS system due to unrecognized ECM signals, potentially affecting vehicle performance. Although the P01P01 code lacks specific details, it is recommended that owners consult a service manual or technician for further clarification. Additionally, some owners suspect that issues with the valve cover and PCT valve, while not directly linked to these codes, can impact overall engine performance and should be promptly inspected by a qualified technician to ensure proper functionality and prevent further complications.
