Honda Rocker Arm Oil Switch
This bulletin applies to 2010-2011 Honda Crosstour vehicles. The MIL may be on, with either DTC P3400 (VPS stuck off Bank 1) or P3497 (VPS stuck off Bank 2) stored. NOTE: The symptom may be intermittent and you may not be able to duplicate after clearing the DTC.
The possible cause is an intermittent failure of the front and/or rear rocker arm oil pressure switch.
Check the engine oil level on the dipstick. If oil level is below the end of the dipstick, this bulletin does not apply. The low engine oil level is likely the cause of the DTC. Continue with normal troubleshooting.
If oil level appears on the dipstick, replace the affected rocker arm oil pressure switch(es).
