if your planning a trip seek diag and est as to prevent issues while on vacation
Was the oil level low? MOST V-TEC codes I've seen are usually due to low oil and to infrequent oil changes. Post SPECIFIC DTC# for a more detailed answer.

IF the oil was not low , or extremely degraded, replace the switch. REF. Honda TSB 13-021
