FI SYSTEM DIAGNOSIS 5-29
Step 2
1) Crank the engine a few seconds with the starter motor, and
measure the CKP sensor peak voltage at the coupler.
2) Repeat the above test procedure a few times and measure
the highest peak voltage.

YES
• Bl/G or B wire open or shorted to ground.
• Loose or poor contacts on the CKP sensor cou-
pler or ECM coupler. (terminal
9
or
D
)
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
NO
• Inspect that metal particles or foreign material
stuck on the CKP sensor and rotor tip.
• If there are no metal particles and foreign mate-
rial, then replace the CKP sensor with a new
one.
When us ing the m ulti-circuit te ster, do no t s trongly
touch the terminal of the ECM coupler with a needle
pointed tester probe t o pr event t he terminal damage
or terminal bend.
