Parts for your 2007 Holden Captiva 5-Crank angle sensor

2007 Holden Captiva 5 crank-angle sensor

Technical sources confirm the 2007 Holden Captiva 5 is fitted with a crank-angle sensor (often called the crankshaft position sensor). The Holden CG Captiva Service Manual (Engine Controls – LY7 3.2L V6 and Z20S1 2.0L diesel), GM Global Service Information, and OEM parts catalogues (ACDelco/Bosch) all list this sensor as a core engine control component on Captiva 5/Maxx models of that year.

This sensor’s job is to tell the engine control module the exact position and rotational speed of the crankshaft, so fuel injection and spark are timed spot on. It also keeps the ECU in sync with the cam sensor for proper sequential injection and VVT control where fitted. Without a clean crank signal, the Captiva can crank but not start, stall when hot, or run roughly with poor fuel economy.

• Common symptoms when the sensor or wiring is failing: hard starting or no start, random stalling (often after heat soak), rough idle or misfire, sluggish performance, and fault codes such as P0335–P0339.
• Location notes: on the 3.2L LY7 V6 it’s mounted low on the block near the bellhousing area, on the 2.0L diesel it’s similarly positioned at the transmission side of the block.

As a rule, the crank-angle sensor isn’t a periodic service item, but it does appreciate a healthy environment. During scheduled servicing, it’s smart to check for oil weeps around the rear of the block, heat-damaged conduit near the exhaust, and loose or corroded connectors. Keeping the loom clipped away from hot spots will save headaches down the track.

1. If replacement is needed, disconnect the battery, raise the vehicle securely, and access the sensor from underneath.
2. Unplug the connector, remove the retaining bolt, and twist-pull the sensor out. A light film of clean oil on the new O-ring helps installation.
3. Route the harness exactly as per factory, refit the bolt torqued to manual spec, reconnect, clear codes, and perform a crank variation learn (CASE) with a scan tool if required by the ECU.

Quality matters here—choose an OE-equivalent sensor (ACDelco/Delphi/Bosch) and avoid forcing the harness. After fitting, a proper scan-tool relearn and a short road test at varying kilometres per hour will keep the Captiva happy under the bonnet.

Where is the crank-angle sensor on a 2007 Captiva 5?

On the 3.2L LY7 V6 it’s typically low on the engine block near the bellhousing/starter area, accessed from underneath. On the 2.0L diesel, it’s also mounted at the transmission side of the block. Expect limited space, a small ratchet and patience help.

Does a crank-angle sensor replacement need a relearn?

Yes, GM systems often require a crankshaft variation learn (CASE). A capable scan tool runs the procedure so the ECU matches the new sensor’s signal to the reluctor wheel. Skipping it can leave rough running or recurrent fault codes.

What fault codes point to a bad crank-angle sensor?

Typical codes include P0335 (crankshaft position sensor “A” circuit), P0336 (range/performance), and related P0337–P0339 variants. Intermittent heat-soak failures may not log a code straight away, so checking live RPM during cranking can help diagnosis.
