WARNING: This page is about a different car, the 2003 Mazda Protege5, 2003 Mazda Protege, 2003 Mazda MX-5 Miata, 2003 Mazda MPV, and 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Mazda6 and MPV air gap inspection procedure and specification not available from manufacturer.

Using a feeler gauge, measure air gap between crankshaft pulley and Crankshaft Position (CKP) sensor. See Fig 1 and Fig 2 . 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. See CRANKSHAFT POSITION SENSOR under ENGINE SENSORS & SWITCHES in REMOVAL, OVERHAUL & INSTALLATION article.
