A23 - Check CKP Circuit Resistance

^ Key off.

^ DVOM on 20K ohm scale.

^ Measure resistance between J48 (CKP- I) and J35 (CKP+ I) at breakout box.

^ Is resistance between 2580 and 2700 ohms?

YES -- GO to A27. A27 - Check CKP Sensor and Trigger Wheel - Key Off

NO -- GO to A24. A24 - Check High or Low Resistance - Resistance Fault
