2000 Lexus ES300 Question: Trouble code P1349
Customer Concern: Setting a code P1349 for a Variable Valve Timing (VVT) Oil Control Valve (OCV) system malfunction. At times the engine runs rough and misfires on one bank. Has an aftermarket remanufactured engine in it. Transmission goes into failsafe when the code sets. Tests/Procedures: 1. When the problem occurs, remove the OCV and see if it is sticking. 2. Can also try unplugging the solenoid, which would keep it from opening and possibly sticking. Potential Causes: Variable Valve Timing (VVT) Oil Control Valve (OCV) - EXPERTEC
this comes a lot from not changing the oil at intervals. sludge gets in the passages and cause the failure. let a shop check it for you. there are tsb on this to replace the solenoid but it is useless if there is sludge in the motor. Roy - mastertech6371
