Engine

P002D — Camshaft Profile Control Circuit Open, "B" Bank 2

Severity: medium Drive with care, to a shop

What P002D means

The engine computer monitors the electrical circuit of the actuator that changes cam profile or valve lift on the bank 2 "B" camshaft. P002D sets when it sees an open circuit or no proper current flow. Without this control, the engine can't adjust valve timing and lift to suit driving conditions.

Symptoms

  • Check Engine light on
  • Reduced power or hesitation
  • Rough or unstable idle
  • Worse fuel economy
  • Possible misfires or stalling
  • Limp mode in some cases

Possible causes

  1. Open or broken wiring in the camshaft profile control circuit
  2. Failed camshaft profile control solenoid or actuator
  3. Loose or corroded electrical connector
  4. Low or contaminated engine oil
  5. PCM failure (unlikely)

How to diagnose

  1. Scan all codes and freeze-frame data, noting any bank 1 or cam timing codes
  2. Check oil level, condition and that it matches the specified grade
  3. Inspect the solenoid wiring and connector for chafing, oil intrusion and corrosion
  4. Measure solenoid coil resistance and compare to the service manual
  5. Test wiring between solenoid and PCM for opens and shorts to ground or power
  6. Check for power and a control signal at the connector with the engine running
  7. Bench-test the solenoid with direct power and confirm it moves freely
  8. If the circuit is good, evaluate the PCM and check for software updates

Common fixes

  • Repair wiring and replace damaged connectors
  • Replace the camshaft profile control solenoid or actuator
  • Change oil and filter with the correct specification
  • Replace or reprogram the PCM (rare)

Questions and answers

What does P002D mean?

It means an open or electrical fault in the bank 2 "B" camshaft profile control circuit. The PCM isn't seeing the expected response from the actuator.

Can I drive with P002D?

Short trips to a shop are usually fine, but power and idle quality may suffer. Avoid long drives until it is fixed.

What most often causes P002D?

Damaged wiring or a bad connector, or a failed solenoid, are the most common causes. Also check oil level and quality.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
