P002E: B Camshaft Profile Control Circuit Low (Bank 2)
Can cause reduced engine performance, poor driveability, and fuel economy issues until resolved
Overview
P002E indicates low voltage or malfunction in the Bank 2 B camshaft profile control circuit in variable valve timing systems
Common Symptoms
- Check Engine Light illuminated
- Reduced engine power
- Poor fuel economy
- Abnormal throttle response
Most Common Causes
Electrical or mechanical failure of the camshaft profile control solenoid is a frequent root cause
Damaged, corroded, loose wiring or pins can cause low voltage signal
Insufficient oil level or poor quality oil may hinder VVT hydraulic actuation
Engine control module issues are less common but possible
Diagnostic Steps
-
Verify and document stored codes with an OBD-II scannerExpected: P002E and any related codes presentInterpretation: Confirms that the circuit fault is current and provides context
-
Check engine oil level and conditionExpected: Oil at proper level and cleanInterpretation: Low or dirty oil can affect VVT operation and should be corrected before further tests
-
Visually inspect wiring and connectors for the Bank 2 B camshaft profile circuitExpected: No visible damage, corrosion, or loose connectorsInterpretation: Issues here indicate electrical faults contributing to low voltage reading
-
Test the camshaft profile control solenoid/actuator signal and resistanceExpected: Actuator responds to commands and resistance is within specInterpretation: Indicates whether the solenoid is functioning
-
Check voltage supply and ground at the actuator connector with key onExpected: Proper reference voltage and groundInterpretation: Rule out wiring or ECM output faults
Repair Solutions
Cost varies by vehicle; solenoid replacement often resolves the majority of P002E cases
Depends on extent of harness damage
Essential maintenance step that can improve VVT performance
Considered only after all circuit and actuator tests are completed
Common Misdiagnoses
Avoid these common diagnostic mistakes:
- Assuming timing chain or belt issue without electrical circuit verification
