Parts for your 2014 Holden Captiva 7-Throttle position sensors

2014 Holden Captiva 7 Throttle Position Sensors

Yes, the 2014 Holden Captiva 7 uses throttle position sensing. Holden/GM Service Information (CG Series II, 2011–2015) identifies an electronic throttle body on the petrol engines (with an integrated throttle position sensor), a throttle valve with position sensing on the 2.2‑litre diesel (for EGR/shutdown control), and dual-track accelerator pedal position sensors. ACDelco parts catalogues note the sensor is integral to the throttle body and not serviced separately on these models, and GM GDS2 diagnostic procedures include throttle/idle learn functions after replacement—confirming the system relies on TPS feedback. Bosch documentation for the 2.2‑litre diesel throttle valve likewise specifies an integrated position sensor.

On a Captiva 7, the throttle position sensor (TPS) tells the engine control module exactly how far the throttle plate is open. Because it’s a drive‑by‑wire setup, the ECU compares the TPS with the accelerator pedal sensors to deliver smooth throttle, solid fuel economy, and stable idle. It’s a safety‑critical, dual‑track sensor designed for redundancy—if signals don’t agree, the ECU will throw a code and may drop the car into limp mode to protect the drivetrain.

For servicing, there’s no separate TPS to swap on the petrol models—it’s built into the throttle body. If the sensor goes out of spec, the fix is replacing the throttle body assembly (and the gasket), then performing a throttle/idle learn with a scan tool such as GDS2. On the diesel, the position sensor lives in the throttle valve assembly, replacement is similar and also needs a learn procedure. The accelerator pedal sensors are a separate pedal module if faults point that way.

• Common symptoms: check‑engine light, uneven idle, surging, hesitation, poor shifting, high fuel use. Typical DTCs include P0120–P0124, P0220, P2101, and P2135.
• Good practice: inspect the connector and loom under the bonnet for rubbing or oil ingress, clean the throttle body bore on petrol engines with proper cleaner (don’t soak the electronics), never try to “adjust” the sensor.
• After battery disconnect or throttle work, carry out an idle/throttle learn. Without it, the Captiva can idle rough or flare.
• Use quality OEM‑equivalent parts (ACDelco/Bosch). Cheap units can trigger correlation faults between the TPS and pedal sensors.

Replacement is straightforward for a trained tech: depressurise, remove intake ducting, unplug the connector, swap the unit, torque evenly, refit, then run the learn. Budget roughly an hour or so, depending on engine and access. Done right, the Captiva’s throttle response comes back crisp and consistent across Kiwi and Aussie conditions.

FAQs

Does the 2014 Captiva 7 have a separate TPS I can replace on its own?
No. On the petrol engines the TPS is integrated into the electronic throttle body, and on the 2.2‑litre diesel it’s built into the throttle valve assembly. If the sensor fails, the whole unit is replaced. The accelerator pedal has its own position sensors, but that’s a separate pedal module.

Do I need a throttle or idle relearn after replacement or a flat battery?
Yes. GM specifies a throttle/idle learn after replacing the throttle body, throttle valve, or pedal module—and often after battery disconnection. Without it, the Captiva may idle poorly or set correlation codes. A scan tool (GDS2 or capable aftermarket) makes it quick and reliable.

What fault codes point to TPS issues on a Captiva 7?
Look for P0120–P0124/P0220 (throttle/pedal sensor circuits), P2135 (throttle/pedal correlation), and P2101 (throttle actuator performance). Intermittent loom faults and dirty throttle bores can mimic sensor trouble, so confirm with live data and wiring checks before replacing parts.
