So finally got around to taking a look at the coil packs. I changed the spark plugs on the passenger side and took a multi-meter to the coils I took out. If anyone knows anything about the resistance these coils should have, that would be great. I tested and wrote down every connections ohms reading but not sure what values are relevant. I have 2 pages of handwritten notes with all the values. It would also be helpful if I had a coil I knew was bad. So anyone know anything about electronics/ohms/resistance and coils? Cause I know nothing
Anyways my findings:
The Denso 673-1303 is identical to the 90919-02259 (08/2003-05/2005). It looks like they might even be made in the same factory and the Toyota logo is milled off. *See attached picture (PS the boots are partially removed)
There is something different about the coils on my 03 LX 90919-02230 (01/1998-08/2003). The wiring/circuitry is different as I got completely different results with the multi-meter on resistance and what connections make a completed circuit. The new 90080-19027 is again wired like my original coils but unlike the Denso 673-1301 or 90919-02259.
I’m not sure if I make any sense on all of this, or if it’s even worth putting time into.
BTW if anyone wants to buy a new, never used Denso 673-1303 or Toyota 90919-02259 Let me know. I’m going to be sticking with the 90080-19027.
