Parts for your 2016 Mazda Cx-5-Crank angle sensor

2016 Mazda CX-5 crank-angle-sensor (crankshaft position sensor) – purpose, servicing and replacement

Technical sources confirm the 2016 Mazda CX-5 is fitted with a crank-angle-sensor, commonly labelled by Mazda as the Crankshaft Position (CKP) Sensor. The Mazda MGSS workshop manual and wiring diagrams for SKYACTIV-G 2.0/2.5 petrol and SKYACTIV-D 2.2 diesel engines show the CKP sensor as a primary engine control input, with related fault codes P0335–P0339. Mazda’s EPC (parts catalogue) also lists the CKP sensor for this model year. It’s absolutely relevant to the vehicle’s engine management.

On the 2016 CX-5, the crank-angle-sensor tracks the crankshaft’s rotational position and speed, giving the PCM precise timing for fuel injection, ignition, variable valve timing, and misfire monitoring. Without a clean signal, the engine can be hard to start, run roughly, or stall. It’s a small, solid-state Hall-effect sensor reading a toothed reluctor wheel on the crank, delivering accurate pulses even at very low cranking speeds.

This sensor isn’t a scheduled maintenance item, but it benefits from sensible servicing checks. During routine services, technicians typically inspect the CKP wiring and connector for oil contamination, heat damage, or chafing, and confirm there are no stored or pending fault codes. Keeping oil leaks in check helps protect the sensor and its connector seal. If the engine has had front or rear main seal work, it’s wise to double-check the CKP harness routing and connector engagement.

Replacement is straightforward but best done with care. Access varies: on SKYACTIV-G petrol it’s commonly mounted low on the block near the transmission bellhousing, on SKYACTIV-D it’s typically near the crank pulley. Good practice is to disconnect the battery, raise and support the vehicle safely, remove any undertrays for access, unplug the connector, remove the single retaining bolt, and swap the sensor with a lightly oiled new O-ring. The retaining bolt should be tightened to factory spec. Most CX-5s don’t require a special relearn, clearing codes and verifying stable RPM and sync on a scan tool is usually enough.

Typical failure symptoms include:

• No-start or long crank, intermittent stall, rough idle
• Tacho dropouts, reduced power, limp mode
• DTCs such as P0335–P0339

Quality matters. Genuine or reputable aftermarket sensors deliver the correct signal amplitude and durability. Expect around 0.5–1.0 hour labour. If faults persist after replacement, a scope check of CKP and cam signals, harness continuity, and engine earths is recommended, as the issue may be wiring or timing-related rather than the sensor itself.

Popular questions about the 2016 Mazda CX-5 crank-angle-sensor

Where is the crank-angle-sensor located on a 2016 Mazda CX-5?
On SKYACTIV-G 2.0/2.5 petrol engines it’s typically low on the engine near the transmission bellhousing, reading a reluctor on the crank. On the SKYACTIV-D 2.2 diesel, it’s commonly at the front of the engine near the crank pulley. Exact access can vary with model year and market, so workshop manual guidance is handy.

What are the common signs the sensor is failing?
Owners often report intermittent no-start, stalling at idle, a wavering tacho, and fault codes like P0335. The engine may crank strongly but not fire, or it might cut out once warm. Because these symptoms overlap with wiring or cam sensor faults, a quick scan tool check and visual inspection of the harness is smart.

Does a new crank-angle-sensor need calibration?
For most 2016 CX-5 variants, no special relearn is needed. After fitting, clear any codes, confirm stable RPM on live data, and road test. Some workshops perform an idle learn or KAM reset as good housekeeping, but the CKP signal itself generally doesn’t require calibration on this platform.
