how timing chain work with crankshaft sensor

What is your question?

I replaced all the engine sensors In my 1996 toyota 4runner. I still have the crankshaft position sensor failure. I replaced this sensor 3 times. The engine dies when idling. The failure PO336 does not disappear. Thanks

What makes this problem better or worse?

Better when disconnecting throttle body pos sensor

How long has your 1996 Toyota 4Runner had this problem?

few years every time getting worse
