An FT86 (BRZ/FRS) came in with a timing issue. This one was different from the standard OCV failure, cam sensor spacing from camshaft, cam gear failure we have previously seen. Upon removal of timing components we found a small indent on the cam angle sensor pick up wheel. The small indent was enough to cause the cam sensor to pick up a second "TDC" causing absolute mayhem. I suspect the wheel was "damaged" during assembly of the engine, but I can not explain why it worked for some time prior to becoming an issue.


Have a great weekend!
