DTC P0341: Variable Valve Timing Control Phase Gap

  1. Perform ECM/PCM reset procedure. See ECM/PCM RESET PROCEDURE/CLEARING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM. Start engine. If DTCs P0341 is set, go to next step. If none of listed DTCs reset, problem is intermittent. System is functioning properly at this time. Check for poor connection(s) or loose wire(s) between Variable Valve Timing Control (VTC) oil control solenoid 2-pin harness connector and Gray ECM/PCM 24-pin "B" harness connector.
  2. Check VTC oil control solenoid valve. See SOLENOIDS under SOLENOIDS & RELAYS in SYSTEM & COMPONENT TESTING article. If VTC oil control solenoid valve is okay, go to next step. If VTC oil control solenoid valve is faulty, clean or replace as necessary.
  3. Remove head cover and check cam chain. See appropriate article in ENGINES. If cam chain is okay, go to next step. If cam chain is faulty, replace it.
  4. Check VTEC actuator. See appropriate article in ENGINES. If VTEC actuator is faulty, replace it. If VTEC actuator is okay, update ECM/PCM or substitute with known-good ECM/PCM. If symptom or indication goes away, replace original ECM/PCM.
