ECM Reprogram Voluntary Emissions Service Campaign
This bulletin applies only to vehicles equipped with SR or Nismo trim level packages.
***** Campaign Summary*****
Nissan has reclassified the previously announced quality action (P8307) for new vehicle inventory as a Voluntary Emissions Service Campaign to update the Engine Control Module (ECM) software to prevent permanent storage of a DTC as a result of a Multiway Control Valve (MCV) malfunction on 853 specific 2018 Nissan Sentra (B17) SR and NISMO vehicles equipped with the MR16DDT engine.
If a MCV malfunction occurred and was repaired, the current ECM logic will allow a technician to reset the Malfunction Indicator Lamp (MIL), but the DTC will remain stored in ECM memory. Resulting in Inspection/Maintenance (I/M; a.k.a. smog test) failure when a DTC check is performed at an inspection station.
