2018 Toyota Hilux Crank Angle Sensor: What It Does, Why It Matters, and When to Replace It

Yes, the 2018 Toyota Hilux is fitted with a crank angle sensor (often listed by Toyota as the crankshaft position sensor/CKP). This is confirmed in Toyota service documentation for the N80-series Hilux (2015–2019) with 1GD-FTV 2.8 diesel, 2GD-FTV 2.4 diesel, and 2TR-FE 2.7 petrol engines, which includes DTCs such as P0335 Crankshaft Position Sensor “A” Circuit and related wiring diagrams. The Toyota Repair Manual, the Hilux Electrical Wiring Diagram manual, and Denso common-rail system training material all describe the CKP as a primary engine control input.

On the 2018 Hilux, the crank angle sensor reads a toothed wheel on the crankshaft and feeds the ECU the exact position and speed of the crank. That live signal is critical for injection timing on the diesels, ignition timing on the petrol variants, and synchronising with the cam sensor for proper start-up and smooth running. If the CKP goes quiet or erratic, the ute can be hard to start, stall, or refuse to fire at all, and the MIL will generally light with a stored fault.

There’s no scheduled replacement interval for the CKP, it’s a solid-state sensor designed to last the life of the engine. As part of sensible servicing, a workshop will usually:

• Scan for fault codes (P0335/P0339 and friends) if there’s a hard start, misfire, or stall complaint.
• Inspect the CKP connector and harness near the timing cover for chafe, oil contamination, or water ingress.
• Check for metal debris at the sensor tip if there’s been internal wear or recent engine work.

Replacement is straightforward if diagnostics confirm the sensor itself is at fault. Battery off, connector off, one retaining bolt out, and the sensor lifts from the timing cover, refit with a fresh O-ring and tighten to the workshop-manual spec. Because the Hilux uses a fixed-gap, ECU-referenced system, no shimming or manual adjustment is required. After refitting, clear codes and verify a clean crank signal and stable idle on a scan tool. On common-rail diesels, a brief relearn/drive cycle helps the ECU settle fuel timing, but no special coding of the sensor is needed.

Owners often chase fuel or glow issues on a no-start when the real culprit is an intermittent CKP signal. A quick scan and a look under the bonnet can save a heap of time—and keep the Hilux doing what it does best.

Popular questions

Where is the crank angle sensor on a 2018 Hilux?
The CKP sits at the front of the engine near the crank pulley/timing cover on GD-series diesels, reading a reluctor on the crankshaft. It’s accessible from the front or underneath once the splash shield is off, with a single bolt and a two- or three-pin connector.

What are the symptoms of a failing crank angle sensor on a 2018 Hilux?
Common signs include long crank or no-start, random stalling at idle, rough running, and the check engine light. Scanning typically reveals P0335/P0339. Wiring damage or oil contamination at the connector can mimic a bad sensor, so testing is key.

Does the 2018 Hilux need a relearn after CKP replacement?
No special coding of the sensor is required. Clear fault codes, start the engine, and let it idle, then take a short drive. The ECU adapts quickly, using a scan tool to confirm a clean, stable RPM signal is good practice.
