What this code means

The intake camshaft on bank 1 is more advanced than the PCM commanded, or the VVT system isn't responding as expected. Often caused by low/dirty oil or a faulty oil control valve.

Common causes for your Acura

  • Low or dirty engine oil (most common—change oil first)
  • Failed or sludged oil control valve (OCV/VVT solenoid)
  • Stretched or worn timing chain
  • Stuck VVT actuator (cam phaser)

Symptoms

  • Check Engine Light
  • Rough idle or rattling on cold startup
  • Poor fuel economy
  • Reduced power

Typical fixes

  • Oil change with correct viscosity oil (often resolves it)
  • Clean or replace oil control valve
  • Replace timing chain if stretched
  • Replace cam phaser if faulty

Repair cost range

For a Acura, repairs for P0011 often fall between $50 and $1200, depending on the cause and whether you use OEM or aftermarket parts. Labor rates vary by location.

Known issues on Acura

Acura P0011 intake cam timing over-advanced on VTEC/VTC-equipped engines typically means a dirty oil control valve (OCV) solenoid screen. Change the oil first with Honda's recommended 0W-20 or 5W-20 full synthetic. If P0011 returns, clean or replace the OCV solenoid—it's inexpensive.
