Parts for your 2010 Holden Colorado-Camshaft sensor

2010 Holden Colorado Camshaft Sensor

Based on technical sources, the 2010 Holden Colorado is fitted with a camshaft position sensor (CMP). The Holden RC Colorado Service Manual (2008–2012, Engine Controls), the Isuzu 4JJ1-TC Workshop Manual (D‑Max/Colorado, Engine Electrical), and GM service information for the HFV6 petrol all specify a CMP for these engines, with diagnostics like DTC P0340/P0341. Major catalogues from OEM-equivalent suppliers (ACDelco, Bosch, Delphi) also list direct-fit CMP sensors for 2010 Colorado variants, confirming its use across the 3.0‑litre 4JJ1 diesel and the petrol options.

What does it do? The camshaft sensor lets the ECU know exactly where the cam(s) are in their rotation. That timing data is essential for sequential fuel injection, stable idle, proper cold starts, variable valve timing on petrol V6 models, and for the diesel’s injection timing and misfire monitoring. When it’s healthy, the Colorado starts crisply, runs smoothly, and uses fuel efficiently. When it’s not, the ECU can’t sync injection to the correct stroke, which can mean long cranks, rough running, or limp mode.

Common signs a CMP is on the way out include:

• Hard starting or extended cranking, especially hot
• Rough idle, flat spots, poor fuel economy
• Check engine light with codes like P0340/P0341
• Intermittent stalling or loss of power

Replacement is straightforward for a trained tech. On the 3.0‑litre 4JJ1 diesel, the sensor sits on the cylinder head at the timing end, on the V6 petrol, each bank has a sensor near the front cover. Usual steps are to disconnect the battery, unplug the connector, remove the retaining bolt, swap the sensor and O‑ring, then torque the bolt to spec and refit the plug. It’s smart to inspect the loom for chafing and oil ingress, clean the connector, and check the crank sensor signal if issues persist, because the ECU relies on both CKP and CMP. Many replacements require no coding, some ECUs may perform a relearn automatically after a few drive cycles. A scan tool can clear codes and confirm cam/crank sync.

There’s no set service interval for the CMP. As part of routine servicing, a workshop can visually check the connector and harness, confirm there’s no oil leak into the plug, and scan for pending cam/crank correlation codes. Using quality parts and keeping the engine oil clean (especially on variable‑valve‑timed petrols) helps the sensor and timing components stay happy over the long haul across Aussie and Kiwi kilometres.

Popular questions

Where is the camshaft sensor on a 2010 Holden Colorado?
On the 3.0‑litre 4JJ1 diesel it’s mounted on the cylinder head at the timing end of the engine. Petrol V6 models have a cam sensor on each bank near the front cover. Exact placement can vary slightly by engine code and body layout, so a service manual or a quick visual check from above usually confirms it.

Can it be driven with a faulty camshaft sensor?
Sometimes it will still run, but starting can be slow and performance patchy, and it may drop into limp mode. Prolonged driving risks stalling at the worst time and can mask other faults. Best bet is to scan for codes and fix it sooner rather than later.

Does a new camshaft sensor need programming?
Most Colorados don’t need coding for a basic CMP replacement. Clear the codes, then the ECU will usually relearn cam/crank correlation after a few start–run cycles. A scan tool helps verify sync and ensure there are no related wiring or crank sensor issues.
