MIL Comes On With One or More DTCs: P0301 thru P0304, P3400, or P3497
(Supersedes 13-055, dated July 19, 2013; see REVISION SUMMARY)
REVISION SUMMARY
2013 Odyssey vehicles were added.
SYMPTOM
The MIL comes on with one or more misfire DTC(s) P0301 thru P0304 (Number 1-4 cylinder misfire detected).
DTC P3400 (rocker arm oil pressure switch B) and/or P3497 (rocker arm oil pressure switch C) may also be stored.
POSSIBLE CAUSE
During a cold start, the engine oil pump outputs high oil pressure. DTCs P3400 and P3497 are set because of the
high oil pressure measured at the VCM spool valve. High oil pressure causes the VCM spool valves to activate,
causing cylinders 1 through 4 to go into cylinder cut mode even though the ECU did not activate the VCM spool
valve.
CORRECTIVE ACTION
Replace the relief valve spring.
PARTS INFORMATION
NOTE: To help clarify where new parts are used in the REPAIR PROCEDURE, the new part is listed in the
applicable step with a “>” symbol.
