Fundamentals of PowertrainControl strategies & OBD IIDiagnosticsEvaporative Emission control system (Pressure sensor)( DTCs 450-455):455):If the evaporative emission control system pressure sensoris experiencing malfunction, fault code 450 is assigned.If the evaporative emission control system pressure sensorhas range/performance problem, fault code 451 is assigned.If the evaporative emission control system pressure sensorhas low input, fault code 452 is assigned.If the evaporative emission control system pressure sensorhas high input, fault code 453 is assigned.If the evaporative emission control system pressure sensoris experiencing intermittent fault, fault code 454 is assigned.If the evaporative emission control system pressure sensoris detected having leak, which is gross, fault code 455 is assigned.
Fundamentals of PowertrainControl strategies & OBD IIDiagnosticsIgnition Coil ( DTCs 350-379):379):Ignition coil diagnostics are performed for deterioration of ignition coilprimary/secondary characteristics. In case of ignition coil primary/secondary electricalcircuit malfunction, fault code 350 is assigned.In case of ignition coil A primary/secondary electrical circuit malfunction, fault code 351is assigned. Similarly for the case of ignition coil B to L primary/secondary electricalcircuit s' malfunction, fault codes 352-362 362 are assigned. If timing reference highresolution signal A has malfunction fault code 370 is assigned. If timing reference highresolution signal A has too many pulses fault code 371 is assigned.If timing reference high resolution signal A has too few pulses fault code 372 is assigned.If timing reference high resolution signal A has intermittent fault, ffault code 373 isassigned.If timing reference high resolution signal A has no pulses, fault t code 374 is assigned.If timing reference high resolution signal B has similar faults, fault codes 375-379379respectively are assigned.
