May help, as an EX Auto elect now retired i can give you the correct test for the CPS, Best done at the ECU , Remove plug from ECU, measure on OHMs resistance on Pins 3 & 4 to spec below
All OK yes....next test, switch your Meter to AC readings and low value [say 10 / 20 AC ] Meter on pins get someone to crank engine over, you should see to spec below.
OHMS 600-1000K
AC Volts.. 2 /4... depends on how fast Cranking, doing these tests at ECU tests the loom as well.
