This forum is great !!! Could any of the Lexus experts please provide me with some insight regarding the CEL code 1349! I have a 2000 Lexus ES300 which appears to be having problems with the variable timing system after having a recent oil system flush. I am receiving a CEL code P1349 and the car is idling rough, along with hard shifting and a stiff brake pedal. The code and the symptoms appear to be related to the VVT system. I read some of the posts and started with OCV. I removed both OCVs, cleaned them and tested them by hooking directly to the battery and they both seemed to be working. I also removed both the OCV filters and cleaned them thoroughly, re installed everything and reset the code. It ran fine for a few minutes and it started idling rough and the dreaded 1349 code reappeared its ugly head again. By the way I am not getting the P1354 code like some people have reported.
Are there any other areas I can check without doing a major overhaul.
Was I supposed to manually advance the timing after cleaning the OCV valves.
What else can cause the dreaded P1349 code. Thanks for any input.
