2004 Nissan 350Z OBD2 Fault Codes P1615, P0132, and P0152 - Diagnosis and Fix Guide

https://www.obd-codes.com/p0132\nhttps://www.obd-codes.com/p0142\nP1615 indicates a security-related issue, typically involving the vehicle key or immobilizer system.\nThe symbols 'Evap X', 'O2S X', 'HRT X', 'CAT X', 'HCAT', 'AIR', and 'EGR' showing as unknown likely reflect that the corresponding diagnostic monitors are not yet ready. This is common after clearing codes, especially if the battery was disconnected. OBD scanners may report these as 'not ready' or show a red circle with a white line, which typically means no data available or monitor inactive.

Thanks Kev,\nthe symbol I received was a red circle with a white line, which I believe indicates 'no entry' or data not available for that system. This is consistent with the monitors being in an 'not ready' state.
