Sensors and ActuatorsEmployed in OBD IIDiagnosticsDiagnosticsOBD II DTCsThe duty cycle of the current pulse that energizes the solenoid ,and the fuel amount are correlated periodically by OBD IIdiagnostics.The failure modes of fuel injector are diagnosed by OBD II. DTCs for these faultsare 251-296.
Functionality of PowertrainControl Module (PCM) inOBD II DiagnosticsPowertrain Control Module (PCM) performs the following functions in relation toOBD II Diagnostics:Perform microprocessor-based self diagnostics to ensurecorrect operation of the PCM and safe storage ofOBD II diagnostic data in memory.Perform On-Board diagnostics in real time and alert thedriver by illuminating MIL in case of a faultPerform powertrain control functions to reduce emissionsand meet OBD II regulations during open-loopoperation at start-up time.Perform powertrain control functions to reduce emissionsand meet OBD II regulations in closed-loop loop controlduring normal operation.
