Parts for your 2015 Toyota Hilux-Crank angle sensor

2015 Toyota HiLux crank angle sensor: what it does and how to look after it

Based on Toyota technical literature, the 2015 HiLux is fitted with a crank angle sensor (Toyota calls it the crankshaft position sensor, CKP). The Toyota Repair Manual and Electrical Wiring Diagram for engines used in 2015 HiLux models (including 1KD‑FTV and 2KD‑FTV diesels, later 1GD‑FTV diesel, plus 2TR‑FE and 1GR‑FE petrols), along with the Toyota Electronic Parts Catalogue, all list a CKP/“NE” sensor. So it’s very much a relevant, critical component on the 2015 HiLux.

On this HiLux, the crank angle sensor reads a toothed wheel on the crankshaft to tell the ECU exactly where the pistons are and how fast they’re spinning. That info is the heartbeat for fuelling, injection timing and, on petrol models, ignition timing. If the signal goes wonky or disappears, the ute can be hard to start, run rough, drop into limp mode, or not start at all.

It’s a solid-state item and not a routine replacement part, but it does live down low on the engine where heat, oil mist and road grime can make life hard. The sensor is typically mounted on the timing cover or engine block and reads the crank pulley reluctor, some variants place it near the flywheel. Either way, it’s worth keeping an eye on the connector and wiring.

• Common hints it’s failing: long crank/no start, random stalling, misfire under load, poor fuel economy, and fault codes such as P0335/P0339.
• Quick checks: look for damaged wiring, loose plugs, oil-soaked connectors, or metal debris stuck to the sensor tip (on magnetic types).

Replacement is straightforward for a competent DIYer, and a breeze for a workshop. Disconnect the battery, unplug the connector, remove the retaining bolt, and pull the sensor. Lightly oil the new sensor’s O‑ring, seat it cleanly, and tighten the bolt to the Toyota spec. On refit, confirm the correct air gap where specified in the workshop manual. Clear any codes, then road test and check live data. No special relearn is usually required, the ECU will sync as soon as it sees a clean signal.

Preventative care boils down to keeping the area clean, making sure the harness isn’t chafing, and using a genuine or quality OEM‑equivalent sensor. If the HiLux has been off‑road through mud and water, a quick inspection under the bonnet after a wash isn’t a bad shout.

• Tip: If the engine still won’t fire after fitting a new CKP, check the cam sensor and timing, as the ECU uses both signals together.

FAQs

Where is the crank angle sensor on a 2015 HiLux?
It’s mounted to the engine so it can “see” a toothed reluctor on the crank. On many 1KD/2KD diesels it’s on the timing cover near the crank pulley, some later engines place it at the rear of the block by the flywheel. A quick look from under the front with a torch usually spots it.

Should the crank angle sensor be replaced during routine servicing?
No. It isn’t a scheduled service item. Replace it only if there are symptoms or stored fault codes. During servicing, it’s smart to inspect the connector and harness for oil contamination or damage, especially if the vehicle does regular off‑road work.

Can a bad crank angle sensor cause intermittent stalling?
Yes. An intermittent or noisy CKP signal can cut fuel delivery or timing, causing random stalls, rough running and hard restarts. Scanning for codes like P0335 and checking live RPM while cranking helps confirm the diagnosis before replacing parts.
