What Does P1532 Mean?
The PCM has detected an open circuit in the control circuit for the 'B' camshaft position actuator (typically exhaust cam) on Bank 2. This disrupts proper variable valve timing operation on the second cylinder bank.
Common Causes
35%
Damaged or broken wiring in the camshaft actuator control circuit
30%
Failed camshaft position actuator solenoid coil
20%
Corroded or loose electrical connector at actuator
10%
Failed PCM driver circuit
5%
Blown fuse in actuator control circuit
Diagnostic Steps
1
Step 1: Visually inspect wiring harness and connector at Bank 2 exhaust camshaft actuator for damage, corrosion, or loose connections
2
Step 2: Use a multimeter to check for continuity in the control circuit from PCM to actuator and verify open circuit
3
Step 3: Measure resistance of camshaft actuator solenoid coil (typical spec 6-12 ohms); replace if out of range or infinite resistance
4
Step 4: Check voltage supply and ground circuits at actuator connector with ignition on
5
Step 5: If all circuits test good, perform PCM driver circuit test or suspect PCM failure
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The PCM has detected an open circuit in the control circuit for the 'B' camshaft position actuator (typically exhaust cam) on Bank 2. This disrupts proper variable valve timing operation on the second cylinder bank.
The most common cause of P1532 ("B" Camshaft Position Actuator Control Open Circuit Bank 2) is: Damaged or broken wiring in the camshaft actuator control circuit
Typical repair costs for P1532 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but may experience reduced performance, poor fuel economy, and rough idle. Extended operation may cause catalyst damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1532 to identify the root cause.
