Crankshaft Position Sensor Air Gap (Except MPV)

Using a feeler gauge, measure air gap between crankshaft pulley and Crankshaft Position (CKP) sensor. See Fig 1 -Fig 5 . If air gap is not .020-.060" (.5-1.5 mm), replace crankshaft pulley or CKP sensor. On Miata, CKP sensor is adjustable. If sensor will not adjust, replace CKP sensor or plate behind crankshaft pulley.
