Parts for your 2020 Toyota Hilux-Crank angle sensor

2020 Toyota Hilux crank-angle sensor — what it does, and when to replace it

Based on Toyota’s service literature for the N80-series Hilux (2015–2020) and common-rail engine control fundamentals from Denso/Toyota technical training, the 2020 Toyota Hilux is fitted with a crank-angle sensor, more commonly listed as a crankshaft position (CKP) sensor. The Engine Control chapter in Toyota workshop manuals describes the CKP as a core input for injection and timing control on the 1GD-FTV 2.8 diesel (and ignition timing on petrol variants). Toyota’s electronic parts catalogues for the 2020 Hilux also list a dedicated CKP sensor and associated harness connector. So yes, this part is relevant and used on the 2020 Hilux.

On a 2020 Hilux, the crank-angle (crankshaft position) sensor is the engine control module’s timekeeper. It tracks the exact position and speed of the crankshaft using a toothed reluctor wheel and a magnetic or Hall-effect pickup. That live signal lets the ECU fire injectors (and coils on petrols) at the right moment, sync with the cam sensor, manage idle stability, control boost and EGR, and keep emissions in check. If it goes out of whack, expect hard starting, sudden stalling, sluggish performance, or a no-start with a P0335–P0339 fault code.

Good news: the CKP isn’t a regular service item. It’s designed to last the life of the engine. During routine servicing, it’s smart to cast an eye over the sensor area for oil weeps, check the connector for dust or water ingress (especially if the ute does river crossings or beach work), and make sure the harness isn’t rubbing on a bracket. A light wipe of the connector and ensuring the locking tab is secure can save headaches later.

If replacement’s needed, go for a quality OE or OE-equivalent unit. The sensor typically mounts to the block aligned with the crank’s reluctor, access varies by engine. Key tips:

• Disconnect the battery before unplugging the sensor.
• Inspect and replace the O-ring if fitted, a tiny nick can become an oil leak.
• Torque the retaining bolt to spec and confirm the air gap if the manual calls it out.
• Clear fault codes and check live data for stable rpm during cranking.

Most Hilux models don’t need coding after a CKP swap, but pairing it with a quick cam/crank correlation check is wise. If your Hilux shows intermittent cut-outs over corrugations, wiggle-test the loom at the sensor — connector issues mimic sensor failure more often than you’d think.

Popular questions about the 2020 Toyota Hilux crank-angle sensor

Where is the crank-angle sensor on a 2020 Hilux?
It’s mounted on the engine block facing a toothed wheel on the crankshaft. Depending on engine variant, it may sit near the front timing cover or low on the block/bellhousing area. A quick look beneath with a torch or a peek in the workshop manual will point to the exact spot for your engine code.

What are the signs the sensor is failing?
Common signs include extended cranking, sudden stalls, rough idle, loss of power, and an engine light with codes like P0335. If the ECU loses a clean crank signal, it may stop fuelling to protect the engine, leading to a no-start until the signal returns.

Do I need to program the sensor after replacement?
Typically, no programming is required on the 2020 Hilux. After fitting, clear any stored codes and verify stable rpm during cranking in live data. If issues persist, check the wiring, connector, and sensor air gap per the service manual.
