Need Known Good Cam/Crank Waveform
Looking for a known good cam/crank waveform for 95 buick 3.8, thanks in advance
Here is a 1998 3.8L
Thanks jamey! I think the channel labels got cut off, im guessing the red channel is 18x and the blue is 3x?
Cha/ckp sync - chb/ckp18x - chc/3xref - chd/cmp
The 1995 3.8 can signal is different from the 1996 3.8 . If you insert a 1996 cam sensor latter in to a 1995 engine platform the ECM with koeo causes the ignition coil to continues fire without the engine turning. Use only a 1995 and maybe a 1994 cam sensor the signals are inversed. In 720 degrees of turning it's only changed in one spot and for a very small time.
good to know.. this vehicle had a bad ckp sensor the 18x signal was erratic. Replaced that sensor and the signal was restored but still getting a cam/crank error code. Just wanted to confirm i had good cam/crank corr before I switch My focus to the ecm
