2016 Holden Colorado Camshaft Sensor: Purpose, Service Tips, and FAQs

Based on GM Global Service Information (GSI) for the RG-series Colorado (2016, 2.8‑litre turbo‑diesel), the vehicle is fitted with a camshaft position sensor. The factory workshop material details DTCs such as P0340 and P0341 relating to the camshaft position (CMP) signal, and includes a CMP replacement procedure. Holden’s Electronic Parts Catalogue also lists a CMP sensor within the engine electrical group for this model, and major aftermarket catalogues carry a direct-replacement sensor specified for the 2012–2016 RG Colorado. So yes, the camshaft sensor is relevant and used on the 2016 Holden Colorado.

The camshaft sensor on a 2016 Holden Colorado isn’t just along for the ride—it’s a key player in how smoothly the 2.8‑litre diesel runs. It feeds the engine control module precise cam position data so the ECU can sync injection events to the correct stroke, manage pilot injection for quieter operation, and keep starts brisk on cold mornings. Working in tandem with the crank sensor, it helps the ECU identify cylinder phase, cut down on rough running, and maintain clean emissions. Without a solid cam signal, owners can see hard starting, limp mode, higher fuel use, and a glowing check engine light.

There’s no fixed replacement interval—this sensor is solid‑state and designed to last—but it does live in a hot, oily spot near the cylinder head, so periodic inspection during scheduled servicing is smart. A quick look for oil weep around the O‑ring, brittled conduit, or a loose connector can prevent headaches later. If fault codes like P0340/P0341 pop up, or the ute cranks longer than normal, idles lumpy, or stumbles under load, a diagnostic scan and a look at live cam/crank sync data will usually pinpoint the issue.

Replacement on the RG Colorado is straightforward for a trained tech: disconnect the battery, access the sensor at the top/side of the head or timing cover area, unplug the connector, remove the retaining bolt, and swap the sensor and O‑ring. A light smear of clean engine oil on the new O‑ring helps it seat properly. Clearing codes and verifying cam/crank correlation on a short road test is good practice. Using a quality OE‑equivalent sensor keeps the ECU happy and maintains crisp starting and smooth drivability.

• Common symptoms: extended crank, intermittent stalling, reduced power, poor economy, check engine light.
• Typical related DTCs: P0340 (CMP circuit) and P0341 (CMP performance). Sometimes P0016 (cam/crank correlation) may appear.
• Service tip: keep the harness clipped away from hot exhaust components and check for oil contamination at each major service.

Does the 2016 Holden Colorado have a camshaft sensor?

Yes. The RG Colorado’s 2.8‑litre turbo‑diesel uses a camshaft position sensor to synchronise injection and smooth out starts and idle. It’s a documented, replaceable component in GM’s service literature and listed in parts catalogues.

What are the signs the camshaft sensor is failing?

Owners often notice longer cranking, a rough idle, flat spots on acceleration, or the check engine light. Scan tools may show DTCs P0340/P0341. If it’s intermittent, heat soak after a hot shutdown can trigger symptoms first.

Is it okay to keep driving with a dodgy camshaft sensor?

It’ll usually start and run, but performance and fuel economy can suffer, and it may drop into limp mode. Prolonged driving risks poor DPF regeneration and added stress on the fuel system. It’s best to diagnose and sort it promptly.
