JA40 - Check CKP Sensor Amplitude at ICM - KOEC

- Key Off.

- DVOM on 40 volt AC scale.

- Crank engine and measure voltage between J48 (CKP+I) and J47 (CKP-I) at breakout box.

- Is settled AC voltage reading greater than 0.4 volts?

YES -- Go to Pinpoint Test Step JC1. JC1 - Check For Spark During Crank

NO -- Amplitude fault. Go to JA41. JA41 - Check CKP Amplitude at ICM - Amplitude Fault
