The MS-CAN on this platform is an internal body network (FORScan), not the generic emissions bus; ISO 15765 CAN only arrived for MY2008. MAF-metered, no MAP. Two banks, two narrowband HEGO O2 sensors per bank. No verifiable mode-22 enhanced PIDs for this pre-CAN J1850 PCM, so none included. Mode-01 0142 module voltage omitted (CAN-era PID); use BATT (ATRV)."
