What Does P1560 Mean?
The electrical circuit controlling the exhaust camshaft position actuator (VVT/VCT) on Bank 1 has an open circuit. The PCM cannot send control signals to adjust camshaft timing.
Common Causes
35%
Broken or damaged wiring between PCM and camshaft actuator
30%
Failed camshaft position actuator solenoid coil
25%
Corroded or disconnected electrical connector at actuator
8%
PCM driver circuit failure
2%
Rubbed-through harness from engine movement
Diagnostic Steps
1
Step 1: Visually inspect camshaft actuator connector for damage, corrosion, or looseness
2
Step 2: Measure resistance of camshaft actuator solenoid (typically 6-12 ohms depending on manufacturer)
3
Step 3: Check continuity from PCM connector to actuator connector on control wire
4
Step 4: Check for battery voltage on power supply wire to actuator with key on
5
Step 5: If wiring and solenoid test good, suspect PCM driver circuit failure
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
The electrical circuit controlling the exhaust camshaft position actuator (VVT/VCT) on Bank 1 has an open circuit. The PCM cannot send control signals to adjust camshaft timing.
The most common cause of P1560 ("B" Camshaft Position Actuator Control Open Circuit Bank 1) is: Broken or damaged wiring between PCM and camshaft actuator
Typical repair costs for P1560 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Reduced engine performance and fuel economy. Vehicle is safe to drive but may lack power and have increased emissions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1560 to identify the root cause.
