2020 Toyota HiLux Camshaft Position Sensor: What It Does and When to Service It

Technical sources confirm the 2020 Toyota HiLux is fitted with a camshaft position sensor (CMP). Toyota’s Repair Manual (TIS) for GUN125/GUN126 series (1GD-FTV and 2GD-FTV turbo-diesel) and 2TR-FE petrol lists “Camshaft Position Sensor – Inspection/Removal/Installation” procedures, the Toyota Electronic Parts Catalogue specifies a “Sensor, Cam Position” for these engines, and Toyota’s diagnostic documentation includes DTCs P0340/P0341 for the CMP circuit on 2020 HiLux models. So yes—this part is relevant and used on the 2020 HiLux.

On the 2020 HiLux, the camshaft sensor feeds the ECU precise information about camshaft angle and timing. That data lets the ECU sync injection events with the crankshaft, manage variable valve timing (where applicable), and deliver clean starts, smooth idle, solid torque, and good fuel economy. If the sensor signal goes wonky, the ute can be hard to start, feel down on power, run rough, or log a check-engine light.

It’s not a routine replacement item, but it does benefit from sensible care during servicing. Keeping engine oil fresh and the right spec helps prevent sludge and varnish that can affect signal quality or O-ring sealing around the sensor boss. During a scheduled service, a quick visual once-over is worthwhile: check the CMP connector for corrosion, broken tabs, or oil wicking in the loom, make sure the harness isn’t rubbing on the rocker cover or bracketry, and scan for stored or pending fault codes that might point to an intermittent signal.

If replacement is needed, it’s a straightforward job for a competent DIYer or any workshop:

• Disconnect the battery and unplug the sensor.
• Remove the hold-down bolt and ease the sensor out—there’s an O-ring that can stick.
• Lightly oil the new O-ring, install the new sensor squarely, and tighten the bolt to the workshop manual spec.
• Clear fault codes and verify live data and starting/idle quality.

Owners often chase misfires or poor economy with filters and fuel treatments first, if the HiLux is still cranky to start or the revs hunt at idle, it’s smart to include the cam sensor and its wiring in the diagnostic plan. A healthy CMP keeps the 2020 HiLux firing on cue, whether it’s a daily commute or a long haul with the trailer on.

Popular questions about 2020 Toyota HiLux camshaft sensors

Where is the camshaft sensor on a 2020 HiLux?
On the 1GD-FTV/2GD-FTV diesels it’s mounted on the cylinder head near the camshaft drive, on the 2TR-FE petrol it’s on the head at the front. It has a small two- or three-pin connector and a single retaining bolt. Exact location varies slightly by engine and build, so a quick look-up in the workshop manual helps.

What are the signs a HiLux camshaft sensor is failing?
Common clues include longer cranking, rough idle, flat spots, reduced power, and a check-engine light with codes like P0340 or P0341. Intermittent faults may only appear when hot or over bumps, so checking the connector and loom is as important as testing the sensor itself.

Do camshaft sensors need regular replacement?
Not typically. They’re replaced on condition, not by kilometres. Good oil quality, tidy wiring, and proper sealing go a long way. If the ECU flags repeated CMP circuit faults and wiring checks out, then fit a quality replacement and reverify with a scan tool.
