Provisional DTC

Provisional DTCs are set only during a single drive cycle. PCM will detect some malfunctions and set DTCs in memory but may not turn on the SERVICE ENGINE SOON/MIL. Provisional DTCs do not necessarily indicate a failure of a component or system. If a component or system fails for 2 drive cycles, a hard fault will be stored. See HARD FAILURES under ON-BOARD DIAGNOSTICS in SELF-DIAGNOSTIC SYSTEM. For additional information on provisional DTCs, see VERIFYING REPAIRS .
