P2B36A Camshaft Profile Actuator B Control Circuit/Open Bank 2

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
P2B36 describes an open control circuit at the second profile actuator of the intake camshaft (camshaft A) on bank 2. A second bank exists only on V or boxer engines. No manufacturer documents this code publicly: the one known user of the series, GM's L3B, is an inline four and only sets the bank 1 code P2B33, where it treats 200 kΩ or more with the driver on as open. V engines with cam-lobe switching do exist, for example Audi's V6 with the valvelift system acting on the intake valves, but their fault codes are not published. CARB requires that output components be checked for circuit continuity and shorts. An open actuator means its cam sleeve cannot change position, so this bank runs without lift switching.
What you may notice
  • Check engine light on
  • Bank 2 intake stays on one lift profile, possibly uneven running between the banks
Likely causes
  • LikelyActuator connector on bank 2 unplugged, loose or corroded
  • PossibleOpen coil in actuator B
  • PossibleBroken control wire between engine module and bank 2
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
