What it means

P002E means the engine control unit has detected a low voltage fault in the control circuit for the 'A' actuator of the 'B' camshaft profile system on Bank 2. The system changes cam profile or valve lift, and the control unit saw a signal voltage lower than expected when it commanded the actuator. Which camshaft is 'B' (intake or exhaust) and how the actuator works depends on the engine, so check the manufacturer data for that model.

Symptoms

Engine warning light on
Rough or unstable idle
Loss of power or flat response, especially at higher revs
Poor fuel economy
Engine may enter a reduced power or limp mode
Possible rattling or ticking from the valve gear if oil supply is involved

Possible causes

Wiring fault in the actuator control circuit, such as a short to ground or chafed insulation, on Bank 2likely
Faulty camshaft profile actuator or solenoid with an internal short or open coillikely
Corroded, loose or damaged connector terminals at the actuator or control unitlikely
Oil contamination or leakage into the actuator connector or harnesspossible
Low or poor-quality engine oil, or a blocked oil feed affecting the actuatorpossible
Fault in the control unit output driverrare
Outdated control unit software where the manufacturer has issued a fix for this code on that modelrare

How to diagnose

Read all stored codes and freeze frame data to see engine speed, load, temperature and whether other cam or timing codes are present.
Check the engine oil level, condition and specification, as the actuator often relies on oil supply.
Visually inspect the Bank 2 actuator, its connector and the harness for chafing, heat damage, oil ingress and corrosion.
Check the connector terminals for tightness and corrosion, and clean or repair as needed.
Measure the actuator coil resistance and compare it with the manufacturer specification for that engine.
Check the control circuit for a short to ground and for continuity between the actuator and the control unit, with the connectors disconnected.
With a suitable scan tool, command the actuator and check it responds and that the circuit voltage changes as expected.
Check for manufacturer service bulletins or software updates relevant to the vehicle.

How to fix

Repair or replace the damaged wiring or connector on the Bank 2 actuator circuit.
Replace the camshaft profile actuator or solenoid if its resistance or operation is out of specification.
Clean or replace corroded terminals and fix any oil leak that is contaminating the connector or harness.
Correct the oil level and change the oil and filter to the correct specification if it is low or degraded.
Update the control unit software only if the manufacturer lists an update for this fault, and replace the unit if the driver is proven faulty.

Can I keep driving?

Medium severity

The car can usually be driven for a short time to get it checked, but expect reduced performance and economy. Avoid hard driving and get it repaired soon, as a continuing fault could affect valve operation and engine reliability.
