crank sensor? - 6G Celicas Forums

Topic #71213 10 posts Started by reggaestylin
what am i do to about the crank position sensor on an obd1 block to obd2 wire system?

i completed the mechanical swap of a 7afe from a 93 corolla into my 97 st (my original engine basically died so i swapped w' a similar engine). i started connecting wires and hoses back and was left w' 1 wire not connected which i found to be the sensor for the crank position, which i believe is resulting in the engine not getting fuel and not running. i've been trying to do as much research as possible but i am still unclear on what to do....
the 93 block does not have a crank position sensor?

is it not part of the oil pump assy, like the 5sfe? if so, you would just need to swap oil pumps, and crank pullys.

93 7afe has no crank sensor, just cam in the dist. you need to swap crank pulleys and timing covers i think to be able to install one.

thanx for the help guys. hopefully in the next couple days i'll find some time to work on it
i found out this morning that the crank position sensor can be easily removed from the old engine by simply unbolting it. this still doesn't help much because i also found out that the slot in which the sensor rests in is part of the oil pump housing. so that means i would have to swap the whole oil pump housings which probably means taking out the engine again. i probably could get this all done but my apartment complex has band residents from doing any car maintenance in the complex and if caught will result in a $100 fee everytime seen working on a car in the complex.

i looked at the sensor n where it sits in it seems that the magnet at the end of the wire signals from detecting the movement of the crank. i was thinking of just rigging it to operate off of some of metal piece that moves simultaneously w' the crankshaft. is this really possible or am i just f*****?

that was exactly what i was saying in my earlier post.
why cant you get the oil pump housing out with the engine in the car?

i would have just unbolt the engine mounts and lower the engine down so you have easier access to the crank pos senser.

you have easy access to it with the wheel off and the fender liner removed.

does anyone have a pdf manual or know exactly how to take off the oil pump housing?
