Crankshaft Position Sensor: MIATA

Loosen CKP sensor bolt. Using feeler gauge, adjust air gap between sensor and crankshaft sensor plate projections to .020-0.59" (0.5-1.5 mm). See Fig 1 . Tighten CKP sensor bolt. If clearance is still not within specification, replace CKP sensor or sensor plate behind crankshaft pulley.
