Question about crankshaft position sensor and timing pully operation

I accidentally broke some of the outer sprockets on the crankshaft timing pulley (see photo). Will this confuse the crankshaft position sensor? Those outer sprockets line up with the position sensor. I am having random/multiple misfire, idle and lack of power issues after a timing belt change and am hoping I have finally found the problem.

i did my t belt recently. not right after... but maybe a week later i noticed it seems like its lost some power. runs great otherwise. guess i need to check this timing. im guessing that ill have to pull the covers and all that to check it, fmr.

Yeah, not too expensive. My 95 uses the old timing system based on a distributor, but I had to change the same part because the keyway groove had become sloppy. Think the pulley was not tightened down properly when the belt was changed. Anyhow, the replacement pulley is the same as yours - with the timing teeth, that my car doesn't use. The teeth are very fragile and easy to break.

Bent teeth may or may not get picked up by the sensor. Best to replace it.

I did this on my very first 1MZ timing belt job by using a prybar to remove the stuck crank sprocket instead of a puller. Replace with junkyard sprocket.
