What P2B36 means
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.
P2B36 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2B36
- Check engine light on
- Bank 2 intake stays on one lift profile, possibly uneven running between the banks
Common causes of P2B36
- Most likelyActuator connector on bank 2 unplugged, loose or corroded
- PossibleOpen coil in actuator B
- PossibleBroken control wire between engine module and bank 2
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2B36 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| B | Area: hybrid propulsion. |
| 36 | The exact fault in that area. |
What to do next
- Note P2B36 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2B36
What does P2B36 mean?
P2B36 means "A Camshaft Profile Actuator B Control Circuit/Open Bank 2". P2B36 describes an open control circuit at the second profile actuator of the intake camshaft (camshaft A) on bank 2. It is a generic code, so it means the same on every make.
Is it safe to drive with P2B36?
Drive gently and only to a workshop. With P2B36 the car can go into limp mode (reduced power) to protect itself.
Will P2B36 fail an emissions test?
Yes, it can. P2B36 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2B36 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2B36 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
