P002F — Camshaft Profile Control Circuit "B" High (Bank 2)

Severity: medium Drive with care, to a shop

What P002F means

The engine control module drives a solenoid that adjusts camshaft profile or timing (VVT) on the second cylinder bank. P002F is set when the voltage in the control circuit for channel "B" is higher than expected. Typical causes are a wiring open or short, a failed solenoid, or a faulty driver inside the ECM.

Symptoms

  • Check Engine light on
  • Reduced engine power
  • Worse fuel economy
  • Rough idle
  • Hesitation or abnormal throttle response

Possible causes

  1. Failed camshaft profile control solenoid (oil control valve) on Bank 2
  2. Dirty, degraded or wrong-grade engine oil
  3. Damaged wiring or poor connection at the solenoid connector
  4. Open circuit or short to voltage in the control circuit
  5. Faulty ECM output driver (uncommon)

How to diagnose

  1. Read all codes and freeze-frame data, clear the code and see if it returns
  2. Check oil level, condition and that it matches the specified grade
  3. Inspect the Bank 2 solenoid connector and wiring for chafing, corrosion and oil contamination
  4. Measure the solenoid coil resistance and compare with the service manual
  5. Check power and control signal at the connector with a multimeter or scope
  6. Test the wire to the ECM for opens and shorts to voltage or ground
  7. Command the solenoid with a scan tool and watch the response
  8. If wiring and solenoid are good, check the ECM and look for software updates

Common fixes

  • Replace the Bank 2 camshaft profile control solenoid
  • Change the oil and filter with the correct specification
  • Repair the wiring or connector in the control circuit
  • Replace or reprogram the ECM if it is confirmed faulty

Questions and answers

Can I drive with a P002F code?

Briefly, yes, but don't put it off. Power and economy drop, and bad oil combined with a faulty VVT system can speed up engine wear. Have it diagnosed soon.

Where should I start with P002F?

Check the oil level and condition, then inspect the Bank 2 solenoid connector and wiring. These are the simplest and most common causes.

What does Bank 2 mean in P002F?

Bank 2 is the cylinder bank that does not contain cylinder 1. Inline engines normally have only one bank, so this code applies to V-type and flat engines.

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.
