Billyd....congrats it looks like the forum administrator restored your original clublexus id name. Here's an update on my 1354, 1351, 300, 302, 304, 306, and 308 codes (all Pass. side), I did all the cleaning and etc., only to notice there was a crack(between the 2 contacts) inside the electrical connector on the ocv itself, the circuit was obviously being shorted. I replaced both ocv's and voila! no more codes.
What is an ocv please

The ocv is the "oil control valve" that controls the flow of oil to variable valve timing (vvt) engines which first appeared on the 1998 Lexus LS and later model engines. There are 2 of these valves, one for each camshaft located on left and right side of the engine. There is a lot of discussion about the ocv's on this and other threads on this forum, in fact its exactly what Billyd was referring to when he responded about "cleaning" them. The "check engine light" codes were the result of a bad ocv, the one located near the passenger side cam on the engine, which I just replaced and the error codes no longer appear.

Had a P1349 pop up. Searched and found it was caused by a OCV on bank one (driver side). This of course triggered misfires all down bank one (cylinders 1,3,5,7). I pulled the valve and put 12v on the prongs and it opened. So I cleaned it, put it back in and drove away. The problem remained. So I did a ton of stuff trying to find what's going on because the valve worked. I finally paid the money and replaced it voila, problem solved. Bottom line, even if the OCV seems to work when power is applied, just swap it out.
