I used to always check mine for pulse, never knew there was an ohm test till recently. If you don´t get a pulse reading on low voltage D/C, try changing to the A/C scale on your meter.
It´s worth it to test the CPS wires at the plug to ECU wires at the plug, with an ohm meter, this will tell you if you have excessive resitance in the C 101 plug.
I jumped the C-1 (purpel with white stripe) and D-1 (white with black stripe) pins at the C/D (same plug) connector at the ECU, with a small piece of solid copper wire and measured resistance in a loop at the CPS connector. Will tell you if there is much/any resistance in the wiring.
I may have the colors for the C-1 and D-1 pins reversed, but it doesn´t really make any difference.
I didn´t find any resistance for the CPS on mine at the C-101 plug, but did find resistance for the TPS, I just jumped the TPS wires at the C-101 plug and left the rest as is, the rest tested OK and had "0" resistance ("If it ain´t broke don´t fix it").
