Parts for your 2019 Toyota Hilux-Camshaft sensor

2019 Toyota HiLux camshaft sensor — fitted, what it does, and how to look after it

Yes, the 2019 Toyota HiLux uses a camshaft position sensor (CMP). This is documented in Toyota’s service literature for the N80 HiLux platform, including the Engine Control System sections for the 1GD‑FTV 2.8L turbo‑diesel and 2TR‑FE 2.7L petrol engines, the Electrical Wiring Diagram (which shows the G2 cam signal circuit alongside the NE crank signal), and the Toyota Electronic Parts Catalogue for these engines. Related diagnostic trouble codes such as P0340/P0342 for “Camshaft Position Sensor” are also listed in the 2019 HiLux repair manual, confirming the part is fitted and monitored by the ECU.

On this HiLux, the camshaft sensor lets the ECU know exactly where the cam is in its rotation so it can sync fuel injection and ignition (petrol) or injection events (diesel) to the correct cylinder at the right moment. It teams up with the crankshaft sensor to sort fast, clean starts and smooth running. On the 1GD‑FTV diesel, accurate cam phase information is critical for pilot/main injection timing and stable idle, on the 2TR‑FE petrol, it also supports variable valve timing control. Without a reliable cam signal, the ute may crank longer, run roughly, drop into limp mode, or not start at all, and it’ll likely throw a check‑engine light with a cam sensor code.

The cam sensor isn’t a routine “replace-at-X‑kilometres” item. During regular servicing, it’s smart to:

• Visually check the sensor connector and harness on the cylinder head for oil seepage, brittle insulation, or loose pins.
• Keep up with oil and filter changes, clean oil helps reduce magnetic debris that can cling to the sensor tip.
• Avoid blasting the area with high‑pressure water around the plug — moisture in the connector can trigger intermittent faults.

Replacement is straightforward for a trained tech: disconnect the battery, unplug the connector, remove the retaining bolt, and withdraw the sensor. Fit a new O‑ring, lightly oil it, seat the new sensor squarely, and torque the bolt to the spec in the Toyota repair manual. A quality OEM‑equivalent part is recommended. After installation, clear any stored DTCs and confirm cam/crank sync and start‑up behaviour with a scan tool. If a no‑start or rough running persists, don’t guess — verify power, ground, and signal integrity at the sensor and the ECU, because wiring faults can mimic a failed sensor.

Common signs it’s time to test or replace the cam sensor on a 2019 HiLux include hard starting (especially hot), misfires or surging, higher fuel use, sudden loss of power with limp‑home, and the MIL on with a P0340‑series code. Proper diagnosis prevents swapping parts unnecessarily.

Does a 2019 HiLux have more than one camshaft sensor?

Most 2019 HiLux engines fitted in Australia and New Zealand use a single camshaft position sensor on the cylinder head. Variants and market specs can differ, but for the common 1GD‑FTV diesel and 2TR‑FE petrol, one CMP sensor provides the cylinder identification the ECU needs for sequential control.

Can a 2019 HiLux run with a failed camshaft sensor?

Often it won’t start, or it may start after extended cranking and then run poorly in limp mode. The diesel in particular relies on the cam signal for accurate injection timing, without it, the ECU may inhibit starting to protect the engine. Always scan for codes and confirm the cam and crank signals before driving on.

Is the camshaft sensor a scheduled replacement item?

No, it’s not a consumable. With clean oil and intact wiring, the original sensor can last the life of the vehicle. Replace only when diagnosis confirms a fault, using an OEM‑quality part, and follow the torque and sealing instructions from the Toyota repair manual.
