P1536 · VolkswagenIntake Camshaft Control Circuit Bank 2 Open

Q: What does code P1536 mean?

Intake Camshaft Control Circuit Bank 2 Open. P1536 on Volkswagen vehicles indicates that the engine control module (ECM) has detected an open circuit in the intake camshaft control circuit for bank 2. The ECM commands the camshaft adjuster to change timing, but the electrical circuit shows no continuity, so the adjuster cannot receive the command signal. This affects engines with variable valve timing on the second bank of cylinders.

AreaVehicle speed, idle control and auxiliary inputs

Symptoms you may notice

Illuminated check engine light, often with no other noticeable symptoms
Rough idle or engine misfire, especially when cold
Reduced engine performance and poor fuel economy
Unusual engine noise or rattling from the timing chain area
In rare cases, the engine may enter limp mode

Common causes, most likely first

Broken or chafed wire in the intake camshaft adjuster circuit for bank 2
Corroded or disconnected electrical connector at the camshaft adjuster solenoid
Failed intake camshaft adjuster solenoid (open coil)
Faulty engine control module (ECM) driver for the circuit
Poor ground connection for the camshaft adjuster circuit

How to diagnose and fix it

Perform a visual inspection of the wiring harness and connector at the bank 2 intake camshaft adjuster solenoid for damage or corrosion
Use a multimeter to check resistance of the camshaft adjuster solenoid; compare to factory specification
Check for continuity and voltage on the control circuit from the ECM to the solenoid, looking for open circuits
Inspect and clean the ground connections related to the camshaft adjuster circuit
If the solenoid fails resistance or continuity tests, replace the intake camshaft adjuster solenoid
If the circuit tests good but the code persists, diagnose the ECM for a faulty driver
Clear the code and perform a road test to verify the repair

What P1536 Really Means for Your VW

An open circuit in the camshaft control circuit often results from a broken wire inside the insulation, which can be missed during a visual inspection.
The camshaft adjuster solenoid may test good when cold but fail when hot, so testing should be done both cold and after warming the engine.
A faulty ECM is rare, but a shorted solenoid can damage the ECM driver, so always check the solenoid before replacing the ECM.
This code is specific to bank 2; on V6 and W12 engines, bank 2 is the opposite side from bank 1, so confirm which bank is affected before ordering parts.
Related codes such as P0011 or P0021 may also set if the timing is affected, but P1536 alone points to an electrical fault, not a mechanical timing issue.

Can I keep driving with P1536?

You can usually drive the vehicle with P1536, but avoid heavy acceleration and high speeds because the engine may lack power and fuel economy will suffer. Prolonged driving with an open circuit may cause the engine to run poorly and could lead to other issues, so schedule a repair soon.
