Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pick-Up Coil/Camshaft Position (CMP) Sensor
Measure pick-up coil/CMP sensor air gap. If gap is not .008-.016" (.20-.40 mm), adjust CMP sensor or replace distributor. Using DVOM, measure pick-up coil/CMP sensor resistance at distributor connector terminals No. 1 (Red wire) and No. 2 (White wire). Pick-up coil/CMP sensor resistance should be 185-275 at 14-122°F (-10-50°C). Replace CMP sensor if reading is not within specification.
