OCV Oil Control Valve (VVT Solenoid) and Filter Question
 

1. Have an 05 Scion xB. I removed the Oil Control Valve (sometimes called the Variable Valve Timing VVT Solenoid) that is located on the right side of the alternator. I was wondering if there was a second valve for the Scion since I know some Toyotas have 2 valves.

2. I thought that the OCR valve FILTER was located just below the OCR, but when I unscrewed that 8mm hex bolt with my Allen wrench, I do not see a filter! Is the filter somehow located deep inside. IF YES, how do I get the filter out?

Thanks for any help

Ok...I was able to see inside the hole that the 8mm hex bolt was in. The tip of the filter is about 1/2 inch inside. I used a stiff wire to slide inside of the hole and snag the filter to pull out. I bent the very tip of the wire to make a hook. You might be able to use the right size fish hook.


The filter was clean, and the solenoid works when tested on a 12 volt battery. BUT it is possible that the valve itself may have hung up inside the shaft instead of sliding in and out easily as it should. I will know more when I replace it when my new valve arrives in a couple of days.


Anyway, I would still like to know if the 05 Scion has 2 of those Oil Control Valves or not. Thanks

The filter screen was 90% clean so I sprayed with a can of carb cleaner anyway. Next I replaced the Oil Control thingeee. It is called an "Engine Variable Timing Solenoid" at Autozone. Car still cranks but will not start. Next I will be double checking all fuses and connections. At this point I am beginning to suspect the ECU since I got a ton of codes all at once when this first happened and vehicle failed to start. I am hoping that it is not the camshaft gear wheel since that is the one part that I may not want to chance replacing by myself... and of course it is an expensive repair.


Grateful for anyone with suggestions that may have had this problem.
