This summary uses the existing diagnostic information shown in full below.
The car's computer is saying that a part that helps control the engine's timing is getting too hot. Think of it like a toy that gets too warm when you play with it for too long.
The P103D code indicates that the camshaft position actuator for bank 2 is experiencing an over-temperature condition.
The camshaft position actuator is an electronic component that adjusts the position of the camshaft to optimize engine performance. When it overheats, it can lead to improper engine timing, which affects engine efficiency and performance.
• Check Engine Light is on
• Engine runs rough
• Reduced fuel efficiency
• Faulty camshaft position actuator
• Low engine oil level
• Blocked oil passages
Camshaft: A shaft in the engine that controls the opening and closing of the engine's valves.
Actuator: A device that moves or controls a mechanism or system.
• Check engine oil level and condition
• Inspect the camshaft position actuator for damage
• Test the actuator's electrical circuit
• Replace the camshaft position actuator
• Perform an engine oil change
• Clean or replace blocked oil passages
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac CTS
• Regular engine oil changes
• Use manufacturer-recommended oil
• Routine engine maintenance
Engine Performance
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional
• Avoid driving the vehicle hard until repaired
Check with your vehicle manufacturer for warranty coverage on engine components.
This code has been associated with issues in vehicles with advanced variable valve timing systems.
Moderate – Should be addressed soon to prevent further engine damage.
Driving with this issue may lead to increased emissions and potential engine damage.
• Engine at normal operating temperature
• Vehicle stationary
The camshaft position actuator is located near the engine's camshaft, typically on the cylinder head.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to poor engine performance and potentially more severe engine damage.
Q: Can I drive with this code?
A: It's not recommended to drive extensively with this code active. Get it checked as soon as possible.
