what's the difference between a 1991 & a 1992 3.0 toyota distributor?

I have a 1992 toyota 4-Runner with a 3.0 v-6. Someone had replaced the engine & i keep getting a no knock signal code. i've replaced the knock sensor & pigtail, i have also checked the wiring to make sure there were no broken wires. The knock sensor i pulled out was different than the 1992 knock sensor. I think i read somewhere that there's a difference between a 1991 & a 1992 distributor. i was wondering if that is what's causing the no knock signal code?

KS,

parts replacement catalog shows '92-'02 is the same sensor. '91 KS be different. i'd like to think it maybe just due to a connector config as 89-95.5 *production* years are basically the same. and same FSM. go with the 92 sensor to match the ecm. then recheck the wiring you changed per ***connector/wire info link below.

then clear the ecm by pulling the EFI mean fuse for 30secs. key off. start it, let it warm, pull codes again.

***wiring, color codes, splice points, and connector configs for that,

EDIT,

i read wrong. you're right. replacement shows 92-85 runner hilux/pu different from the 91.

cap, rotor, ignitor differ. but coil is gen good.

what's the difference between a 1991 & a 1992 3.0 toyota distributor?
