Parts for your 2014 Mazda Cx-5-Crank angle sensor

2014 Mazda CX-5 crank-angle sensor (crankshaft position sensor)

Technical sources including the Mazda CX-5 Workshop Manual (2013–2016, Engine Control System sections for SKYACTIV-G and SKYACTIV-D), Mazda electronic parts catalogues listing a “Crankshaft Position (CKP) Sensor” for 2014 CX-5 petrol and diesel engines, and independent service data (e.g., Autodata/Haynes engine management overviews) confirm that a crank-angle sensor—also called the crankshaft position sensor—is fitted and is essential on the 2014 Mazda CX-5.

On the 2014 Mazda CX-5, the crank-angle sensor keeps the engine computer in the loop about the exact position and rotational speed of the crankshaft. That live signal lets the ECU time fuel injection and spark bang-on, run variable valve timing properly, and monitor misfires. Without a healthy CKP signal, the CX-5 can be a pig to start, run rough, or not run at all.

Mazda mounts the sensor at the engine block near the crankshaft—typically down low by the bellhousing on the SKYACTIV-G petrol engines and near the front cover on the SKYACTIV-D diesel. It’s a solid-state unit reading a toothed reluctor on the crank, so there’s no periodic adjustment. It’s not a scheduled service item, but it does appreciate a bit of attention during routine servicing.

• What to watch for: intermittent no-start, sudden stalling, a dead tach while cranking, rough idle, poor economy, and an illuminated MIL with codes like P0335–P0339.
• Quick checks at service: inspect the connector and wiring for chafing or oil contamination, ensure the harness is clipped and clear of the driveline, and look for oil leaks that could wick onto the plug.

If replacement is needed, use a quality genuine or OE-equivalent sensor and a fresh O-ring. Typical approach: disconnect the battery, safely raise the vehicle, unplug the connector, remove the retaining bolt, withdraw the sensor, lightly oil the new O-ring, install, and tighten to the manufacturer’s spec. Route the loom exactly as Mazda intended to avoid future rub-through. After refit, clear fault codes, perform an idle/trim relearn if required, and road test. On high-kilometre cars, it’s smart to check the camshaft sensor and related grounds at the same time, as the ECU uses both signals together.

Handy tip: don’t blast the area with a pressure washer—moisture forced into the connector is a common cause of intermittent dramas. A quick visual once a service can save a tow later.

Does a 2014 Mazda CX-5 have a crank-angle sensor?

Yes. Mazda fits a crankshaft position (crank-angle) sensor to both the SKYACTIV-G petrol and SKYACTIV-D diesel engines. It’s critical for timing fuel and spark and for misfire monitoring, so the car won’t run properly without it.

Where is the crank-angle sensor on a 2014 CX-5?

It’s mounted at the engine block reading a toothed wheel on the crank. On most petrol models it’s down low near the transmission bellhousing, on diesel variants it’s typically at the front of the engine by the timing cover. Access is usually from underneath.

How much does replacement cost on a 2014 CX-5?

In Australia and New Zealand, expect roughly $80–$250 for the sensor depending on brand, plus about 0.5–1.0 hour of labour. Drive-in, drive-out totals commonly land in the $200–$450 range, varying with engine, workshop rates, and access.
