MATT RR Posted December 12, 2015 Share Posted December 12, 2015 Just a quick write up on how I cleaned my Oil Control Valve (OCV) and filter on my VVTI Supra. The valve itself controls the oil pressure sent to the VVTi intake cam. I changed this more as a prevention than a cure. I decided to replace the following two parts with new Toyota parts instead of cleaning them, as they are very cheap: Oil Control Valve Filter Washers for the union bolt OCV o-ring In the end I didn’t use the new o-ring as the OCV was in very good condition as was the o-ring Tools Required: 10mm socket 22mm spanner 5mm Alan key Cloth/cleaning rag First, the two plugs need to be unplugged/removed so you can access the union bolt as pictured: Then, using the 22mm spanner under the nut to remove the union bolt and washers, careful not to drop the washers! The bolt should come out with the OCV filter attached as pictured: The filter easily pops off, here is the old and new filter: If you are not replacing the part then clean it all up with a degreaser, be very careful with the mesh if doing this! Then pop it all back in reverse of the process to take it out so you end up with it looking like this: Next up is cleaning the actual OCV, to do this remove the cam cover bolts and then the cam cover, this reveals the OCV (circled), remove the nut holding it in place (as per pic) and slide the OCV out: The end of the OCV Where the OCV sits: Give the OCV a good clean with a degreaser/cam cleaner, if the o-ring needs replacing nows the time to do it but it shouldn’t really be necessary. Then put it all back together in reverse of the above process: Put the cam cover back in place and its all done. According to a US forum this can be done if you have idle issues on your VVTI, or if there are error codes such as code 59 for supra and P1329 for IS300/Aristo which may be cleared by cleaning the OCV if there are issues with the VVTi system. I did mine our of interest/prevention/boredom etc J Anyway I hope someone finds this useful Quote Link to comment Share on other sites More sharing options...

David P Posted December 14, 2015 Share Posted December 14, 2015 The end of that OCV looks poorly? Is that secondary belt line on the cam pulley an old wound, or is the belt tensioner on it's way out? Quote Link to comment Share on other sites More sharing options...
MATT RR Posted December 14, 2015 Author Share Posted December 14, 2015 The end of that OCV looks poorly? Is that secondary belt line on the cam pulley an old wound, or is the belt tensioner on it's way out? Hi David, the end of the OCV cleaned up, it was just some oil on the end, belt and tensioner should be fine just had them changed by SRD: Quote Link to comment Share on other sites More sharing options...
David P Posted December 14, 2015 Share Posted December 14, 2015 (edited) I can see it's a new belt, was the tensioner arm and bearing renewed too? In your latest pic the belt is running a different line on the pulleys, maybe that pic was taken before the engine was turned? Are you sure about that OCV end, in the pic it looks as if the casting is failing?

adam1983 Posted December 22, 2018 Share Posted December 22, 2018 Does anybody know if part number 15330-46011 is interchangeable with 15330-46010? I ordered the 46010 from Toyota and received 46011. The end looks slightly different but not sure if it makes any difference. Quote Link to comment Share on other sites More sharing options...
shifted Posted February 22, 2022 Share Posted February 22, 2022 @adam1983 did you manage to answer your query above? Interested to know. Mine has started to hunt idle so trying to figure out what part it could be that needs replacing. Quote Link to comment Share on other sites More sharing options...
Scooter Posted February 22, 2022 Share Posted February 22, 2022 some interesting info here, but I was trying to find a VVTI throttle body reset procedure for you and might help........will post another link if I do! Quote Link to comment Share on other sites More sharing options...
Scooter Posted February 22, 2022 Share Posted February 22, 2022 (edited) This mentions the reset, but I can't see the exact procedure....opps yes it does see below. Try reset the ETCS-i system – Turn the key to the “ON” position but don’t turn over the car, put your foot completely down on the throttle “Gas” pedal for 30 seconds, you should hear a beeping/humming sound while the ETCS-i system resets, turn the ignition to “Off”. Now turn the car back over and re-test to see if you have any symptoms Edited February 22, 2022 by Scooter (see edit history) Quote Link to comment Share on other sites More sharing options...

The part number was slightly different as mentioned in my comment. I was told by Toyota that it was a newer version but works the same as the previous. Had no issues since it was changed out.
