2014 Holden Colorado Crank Angle Sensor: What it does and when to replace it

Yes, the 2014 Holden Colorado (RG) uses a crank angle sensor—also called a crankshaft position (CKP) sensor. This isn’t optional kit, it’s a core engine control input. Technical sources that document the sensor include the Holden RG Colorado Service Manual (Engine Controls and Fuel – Diesel), GM Global Service Information for 2014 Colorado covering DTCs P0335/P0336, and the ACDelco/GM OE parts catalogue, which lists a CKP sensor for 2012–2016 RG models. Petrol variants and the 2.8‑litre Duramax turbo‑diesel both rely on it.

What’s its job? The crank angle sensor tracks the exact position and speed of the crankshaft. The ECU uses that signal to fire injectors, sync with the cam sensor, manage fuel, and stabilise idle. Without a clean CKP signal, the Colorado can crank for ages, stumble, or not start at all. It’s also tied into traction and stability logic, so a sick sensor can trigger warning lamps and limp mode.

There’s no scheduled maintenance for the sensor itself. It’s a replace‑on‑condition item. Typical symptoms include hard starting, intermittent stalling, sudden loss of power, a dead tachometer during crank, or the MIL on with P0335/P0336 stored. On the RG, the CKP is usually mounted on the engine block/timing case area and reads a toothed reluctor on the crank—access is most often from underneath with a single retaining bolt.

• Before replacing, scan for codes and check live data for an RPM reading while cranking, no RPM usually points to CKP signal loss.
• Inspect the connector and harness routing near the block and engine mounts—heat, oil wicking, or chafe can mimic a bad sensor.
• If replacing, use quality OEM‑spec parts, fit a new O‑ring, and keep the magnetic tip clean (no metal filings). Don’t crank the engine with the sensor removed.
• After installation, perform a crank variation learn (CKP relearn) with a capable scan tool. GM/Holden service info specifies this so the ECU maps the new signal correctly.
• If problems persist, check the crank reluctor wheel for damage or excessive end‑play before condemning the new sensor.

Done right, the job is straightforward and typically a short workshop visit. Skipping the relearn or ignoring wiring faults is what tends to drag it out.

Popular questions

Does a 2014 Holden Colorado have a crank angle sensor?
Yes. Both the 2.8‑litre turbo‑diesel RG Colorado and petrol variants use a crank angle (crankshaft position) sensor. This is confirmed in Holden/GM service information and parts catalogues for the 2014 model year.

Where is the crank angle sensor on a 2014 Colorado, and is it hard to replace?
On the RG, it’s typically mounted to the engine block or timing case, reading a toothed wheel on the crank. Access is generally from underneath, one retaining bolt and a sealed fit. Most techs allow under an hour if there’s good access and no seized fasteners.

What fault codes point to a bad crank angle sensor, and do you need a relearn?
Common codes are P0335 (CKP circuit) and P0336 (CKP performance/range). After replacing the sensor, a crank variation learn with a suitable scan tool is recommended so the ECU correctly recognises the new signal and avoids rough running or repeat faults.
