Parts for your 2016 Holden Colorado-Crank angle sensor

2016 Holden Colorado crank angle sensor: what it is, why it matters, and how to look after it

Technical sources confirm the 2016 Holden Colorado (RG series, 2.8L Duramax turbo‑diesel) is fitted with a crank angle sensor, more formally the crankshaft position (CKP) sensor. GM Global Service Information (Model Year 2016, Colorado RG, Engine Control – 2.8L Diesel XLD28/LWN) describes the CKP sensor’s role and diagnostics, including DTCs P0335–P0339. The Holden Colorado RG Workshop Manual (2012–2016) includes a “Crankshaft Position Sensor – Removal and Installation” procedure, and GM Genuine Parts/ACDelco catalogues list a CKP sensor for this engine. Together, these technical references establish that the crank angle sensor is relevant and fitted to the 2016 Colorado.

On the 2016 Colorado, the crank angle sensor tells the engine control module exactly where the crankshaft is and how fast it’s spinning. That data is the heartbeat for fuel injection timing, pilot injections, start-up fuelling, and idle stability. Paired with the cam sensor, it keeps the 2.8 Duramax in sync, prevents misfires, and helps the ute pull cleanly under load. If the sensor signal goes missing or messy, expect long cranking, a no‑start, sudden stalling, rough idle, limp mode, or the check engine lamp with codes like P0335/P0336.

There’s no scheduled replacement for the CKP on this model, but it’s smart to keep an eye on it during regular services (every 10,000–15,000 km, or as per the book). Because the sensor sits low on the block near the bellhousing, road grime and the odd oil mist can build up. A quick visual check for oil leaks, damaged loom insulation, loose connector locks, and chafing above the starter goes a long way. If the engine’s been making metal or there’s clutch/flywheel debris, the sensor’s magnetic tip can collect swarf—cleaning may restore a clean signal, but if faults return, replacement is the go.

• Typical replacement steps: disconnect the battery, raise the vehicle safely, unplug the sensor, remove the retaining bolt, twist and withdraw the sensor, lightly oil the new O‑ring, install and torque to the specification in GM SI, reconnect, then clear codes.
• Always perform a crankshaft position variation relearn with a capable scan tool after replacement so the ECM can resync—this is called out in GM service procedures.
• Use quality OE‑equivalent parts, route the harness in the factory clips, and avoid running it tight against the starter or exhaust—heat and electrical noise are the enemies here.

If the ute is hard to start when hot, the tacho flickers, or it drops into limp with CKP‑related codes, it’s time for testing with a scan tool or oscilloscope and, if confirmed, a fresh sensor. Done right, the job is straightforward and restores clean, drama‑free running.

Popular questions about the 2016 Holden Colorado crank angle sensor

Where is the crank angle (crankshaft position) sensor located on a 2016 Colorado?
On the 2.8L Duramax diesel it’s mounted low on the engine block near the transmission bellhousing, typically above or near the starter. It reads a toothed reluctor on the crank. Access is usually from underneath once the vehicle is safely raised.

What fault codes point to a bad crank angle sensor?
Common codes are P0335 (Crankshaft Position Sensor “A” Circuit) and P0336 (Range/Performance). Intermittent signal or correlation issues can also flag related codes. Always check wiring and connector condition before condemning the sensor.

Do I need a relearn after replacing the sensor?
Yes. A crankshaft position variation relearn is required using a capable scan tool. GM’s service information specifies this step so the ECM can accurately map crankshaft variations for smooth idle and precise injection timing.
