Parts for your 2013 Mazda Premacy-Crank angle sensor

2013 Mazda Premacy crank-angle sensor: what it does and how to look after it

Referencing technical sources, the 2013 Mazda Premacy is fitted with a crank-angle sensor (commonly called a crankshaft position or CKP sensor). The Mazda Premacy/Mazda5 factory workshop manuals for LF/L5-series engines (Mazda Service Information, 2012–2015), Autodata engine management data for the 2.0/2.5 petrol variants, and common DTC listings (P0335–P0339) all specify a CKP sensor mounted at the front of the engine reading a toothed reluctor on the crank. Aftermarket catalogues (Denso/NTK) also list a direct-fit CKP for 2013 Premacy. So yes, the crank-angle sensor is absolutely used on this model.

On the 2013 Premacy, the crank-angle sensor is the timekeeper for the whole show. It tracks crank speed and position so the ECU can trigger spark and fuel bang-on time, coordinate with the cam sensor, and keep features like i-stop (idle-stop) smooth. If the sensor signal goes missing or messy, expect hard starting, random stalling, rough idle, long cranks after i-stop, a dead tach during crank, or the MIL lit with P0335/P0336.

It’s a sealed, maintenance-free sensor, but it lives down low where heat, oil mist and road grime aren’t exactly friendly. As part of routine servicing, it’s smart to:

• Visually check the sensor connector and harness routing under the bonnet for chafe, oil contamination, or loose clips.
• Scan for stored or pending DTCs even if it seems to run fine, CKP issues can be intermittent.
• If there’s oil seepage near the front cover, fix the leak so it doesn’t wick into the connector.

Replacement is straightforward for a competent tech: battery disconnected, splash shield off, unplug the sensor, remove the single retaining bolt, swap the sensor and O-ring, and refit. Tighten the bolt to workshop-manual spec (typically around 8–10 N·m), lightly oil the O-ring, then clear codes and perform an idle/ECU relearn if needed. Access varies slightly between LF (2.0) and L5 (2.5) setups, but it’s usually done from underneath. Use quality OE-equivalent parts (Denso/NTK/Mazda Genuine) because signal quality matters. There’s no set replacement interval, it’s a fix-on-failure item, but a quick inspection at major services (e.g., every 100,000 km) helps prevent surprises.

If the Premacy starts stalling at lights, cranks a long time when hot, or logs P0335/P0336, don’t keep driving and hoping. A failing crank-angle sensor can become a no-start with zero warning, and that’s never fun on a Kiwi back road or an Aussie motorway.

Popular questions about the 2013 Mazda Premacy crank-angle sensor

Does a 2013 Mazda Premacy actually have a crank-angle sensor?
Yes. Mazda’s own workshop manuals for the Premacy/Mazda5 list a crankshaft position (crank-angle) sensor on the 2.0 and 2.5 petrol engines. It reads a toothed wheel on the crank and is essential for spark and fuel timing.

What are the typical symptoms of a failing crank-angle sensor?
Common signs include hard starting, random stalls, rough idle, sluggish throttle, a dead or jumpy tacho during cranking, and fault codes like P0335 or P0336. With i-stop models, you might notice longer restart times. If ignored, it can progress to a no-start.

Can you keep driving with a dodgy crank-angle sensor?
It’s risky. The car may run one minute and stall the next. Short trips to a workshop might be okay if it’s still starting, but plan for a tow. Fixing it early avoids being stranded and may protect the catalyst from misfire-related damage.
