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. Measure pick-up coil/CMP sensor resistance at appropriate distributor harness connector terminals. Pick-up coil/CMP sensor resistance should be 240-325 ohms at 122-212°F (50-100°C). Replace CMP sensor if resistance is not within specification.
