MIL Comes On With One or More DTCs: P0301 thru P0304, P3400, or P3497
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.
WARRANTY CLAIM INFORMATION
The normal warranty applies.
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.

NOTE: To help clarify where new parts are used in the
REPAIR PROCEDURE, the new part is listed in the

DIAGNOSIS
1. Connect the HDS, and check for any of these
DTCs: P0301, P0302, P0303, P0304, P3400,
and/or P3497.
• If one or more DTCs are set, go to step 2.
• If no DTCs are set, this bulletin does not apply.
Continue with normal troubleshooting.
2. Check the on-board snapshot (at time 0) or the
freeze frame data. Look at the ROCKER ARM OIL
PRESSURE value.
• If the value is greater than 92 psi, go to step 3.
• If the value is 92 psi or less, this bulletin does not
apply. Continue with normal troubleshooting.
3. Check the on-board snapshot (at time 0) or the
freeze data. Look at the ECT SENSOR 1 value.
• If the value is less than 30° F, go to REPAIR
PROCEDURE.
• If the value is 30° F or warmer, this bulletin does
not apply. Continue with normal troubleshooting.
