C3: Check Harness Continuity - Power (Mechanical Guard)

With EM010 & EM011 disconnected, measure the resistance between
PI042/004 & EM011/008
PI042/004 & EM010/021

Is the resistance < 0.5 ohms?

Yes
Go to C4 C4: Check Harness Continuity - Ground (Mechanical Guard)

No
Inspect PI042, EM011, EM010 & PI001 for bent/pushed back pins or locate & repair the harness/splice EMS01 or PIS09

If OK? Go to C18 C18: Check Sensor Supply Voltage
