| Related dtcs | Group of diagnostic trouble codes that are output by ecm based on same malfunction detection logic. |

"Once per driving cycle" means ecm only performs checks for that malfunction once during single driving cycle. "Continuous" means ecm performs checks for that malfunction whenever enabling conditions met. |
| Duration | Minimum time for which ecm must detect continuous deviation in monitored value(s) in order to set dtc. Timing begins when typical enabling conditions met. |
| Malfunction thresholds | Value, beyond which, ecm determines malfunctions exist and sets dtcs. |
| Mil operation | Timing of mil illumination after malfunction detected.
"Immediate" means ecm illuminates mil as soon as malfunction detected. "2 Driving cycle" means ecm illuminates mil if same malfunction detected second time during next sequential driving cycle. |
