Parts for your 2015 Holden Colorado-Crank angle sensor

2015 Holden Colorado crank-angle sensor — fitment, purpose and service tips

Yes, the 2015 Holden Colorado is fitted with a crank-angle sensor (commonly called a crankshaft position sensor or CKP). Technical documentation including the Holden RG Colorado Service/Workshop Manual for the 2.8‑litre diesel (Engine Controls section) lists the CKP, its signal characteristics and related diagnostic trouble codes (P0335–P0339). GM Service Information and GDS2 procedures also reference a crankshaft position variation learn after replacement. Major parts catalogues from OE and aftermarket suppliers (e.g., NTK/NGK, Delphi) show direct-fit CKP sensors for the 2012–2016 RG Colorado. Those sources confirm the sensor is standard equipment and critical to engine management.

On the 2.8‑litre turbo‑diesel, the crank-angle sensor reads a toothed wheel on the crankshaft (at the rear of the block near the bellhousing) and feeds the engine control module precise engine speed and position data. That signal is the backbone for injection timing, fuel delivery and torque control. If the signal drops out or goes noisy, the ute may crank but not start, stall unexpectedly, surge, or throw the MIL with codes like P0335. Because modern common‑rail diesels rely on this reference, a failed sensor can leave the Colorado going nowhere fast.

It’s not a scheduled replacement item, but given its harsh under‑vehicle environment, periodic inspection during servicing is smart. A tech will usually:

• Check the harness and connector for oil ingress, rubbed insulation, or loose pins
• Verify the sensor mounting is clean and correctly seated, with no metallic debris on the tip
• Scan for pending codes and review live RPM during crank to confirm a solid signal

Replacement is straightforward for a competent DIYer, though many owners prefer a workshop to handle it:

• Disconnect the battery and safely raise the vehicle for access underneath
• Unplug the connector, remove the retaining fastener, and ease the old sensor out
• Lightly oil the O‑ring on the new unit, seat it squarely, and torque the bolt to spec
• Clear codes and perform a crankshaft position variation learn with a scan tool if specified by GM/Holden procedures

Genuine or OE‑quality sensors are worth it here, cheap copies can cause hot‑start grief or intermittent stalls. If the Colorado shows hard starting after a long run, random cut‑outs, or erratic tacho behaviour, a CKP check belongs near the top of the list. Keeping the wiring clipped away from exhaust heat and free from oil leaks will help the new sensor live a long, drama‑free life.

Popular questions about 2015 Holden Colorado crank-angle sensors

Where is the crank-angle sensor on a 2015 Holden Colorado?

On the 2.8‑litre diesel, it’s mounted at the rear of the engine block near the bellhousing, reading a toothed wheel on the crank. Access is usually from underneath, removing undertrays or splash shields helps.

What are the common symptoms of a failing crank-angle sensor?

Hard starting or no‑start when hot, intermittent stalling, rough idle, surging, the tacho dropping to zero, and the MIL illuminated with codes such as P0335. A scan showing zero RPM while cranking is a classic giveaway.

Do you need to perform a relearn after replacing the sensor?

Many RG Colorados require a crankshaft position variation learn with a suitable scan tool after CKP replacement. It helps the ECM match the new sensor’s signal to the engine’s unique tooth profile for clean starts and smooth running.
