What does it mean?
P1532 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Camshaft Control Circuit Open .
Symptoms
- Check engine light on with reduced torque, felt as an uneven pull between the two halves of the engine
- Rough idle that may improve when the engine is fully warm
- Rattling on start-up from the timing drive
- Slow throttle response and higher fuel consumption
- No solenoid operation noise on the affected circuit
- Companion camshaft timing codes may also be present
Likely causes
- Open winding in the camshaft control solenoid on that circuit
- Terminal backed out of the connector or a connector not fully engaged after service
- Broken conductor in the harness branch feeding that solenoid
- Loss of supply voltage from a blown fuse or a corroded splice shared with the other solenoid
- High resistance from corrosion in the connector after water or oil ingress
- Poor ground for the actuator circuit
- Module driver failure on that specific output
How to fix it
- Identify which solenoid belongs to the affected circuit from the wiring information for that engine
- Measure the winding resistance of both solenoids and compare them; an open reading identifies the failed one
- Check the connector for seating, corrosion and pushed-back terminals
- Check supply voltage and continuity on the control wire back to the module
- Inspect the shared splice or fuse if both circuits behave oddly
- Repair the harness or replace the solenoid on the affected circuit
- Command both solenoids after the repair and confirm each camshaft angle responds
