Fundamentals of PowertrainControl strategies & OBD IIDiagnosticsSecondary air injection system ( DTCs 410-419):419):Secondary air injection system diagnostics areperformed for deterioration of Secondary air injection system flow characteristics. In case ofSecondary air injection system malfunction, fault code 410 is assigned. aIn case of Secondary airinjection system incorrect flow, fault code 411 is assigned. In case of Secondary air injectionsystem switching valve A circuit open , fault code 413 is assigned.In case of Secondary air injection system switching valve A circuit shorted , fault code 414 isassigned. In case of Secondary air injection system switching valve B circuit malfunction, open ,or shorted, fault codes 415-417 417 are assigned respectively. In case of Secondary air injectionionsystem Relay A circuit malfunction , fault code 418 is assigned. In case of Secondary airinjection system Relay B circuit malfunction , fault code 419 is assigned.Secondary air injection system diagnostics are described in detail in later section.
Fundamentals of PowertrainControl strategies & OBD IIDiagnosticsFuel level Sensor ( DTCs 460-464):464):Fuel level sensor circuit diagnostics are performed for deterioration of fuel levelsensor characteristics. In case of fuel level sensorcircuit malfunction fault code 460 is assigned. If thefuel level sensor circuit is indicating out of range/performance problem, faultcode 461 is assigned. If the fuel level sensor circuitis indicating very low reading, fault code 462 is assigned. If thefuel level sensor circuit is indicating very high reading fault t code 463 is assigned.The expected value is estimated using flow parameters. If thefuel level sensor circuit is indicating intermittent faulty reading, fault code 464 isassigned.
