2) Measure resistance between "BLK/ORN" wire terminal
of CKP sensor connector and engine ground.
Is measured resistance value less than 3
6 Was terminal "B+" voltage in Step 3 within specification?
7 Engine start signal check
1) Check starting motor circuit for opening and short
referring to Step 2 of "DTC P0616: Starter Relay Circuit
