Parts for your 2013 Holden Captiva 7-Throttle position sensors

2013 Holden Captiva 7 Throttle Position Sensors

Holden’s own CG Series II workshop documentation and GM Global Service Information for the 2013 Captiva 7 describe an electronic throttle control system. In this setup, the throttle body houses dual, independent throttle position sensors (TPS) that report the throttle plate angle to the engine control module (ECM). Petrol variants use a drive‑by‑wire throttle body with built‑in TPS, and the 2.2‑litre diesel uses an electronically actuated intake throttle valve with position feedback for EGR management and smooth shutdown. So, a throttle position sensor is absolutely relevant and fitted to the 2013 Holden Captiva 7.

What does the TPS actually do? It constantly tells the ECM how far open the throttle plate is. The ECM cross‑checks this with the accelerator pedal position sensors to deliver smooth acceleration, stable idle, correct cruise control behaviour, tidy gear changes, and proper emissions control. On the diesel, throttle plate position also helps with EGR flow and can influence DPF regeneration strategy.

There’s no scheduled replacement for the TPS because it’s integrated into the throttle body/actuator. However, the system does appreciate clean airways and solid electrical connections. Keeping the throttle bore clean of gum and soot (on diesels especially) helps the plate move freely and keeps the sensor readings consistent. Avoid drowning the electronics in cleaner—spray onto a cloth and wipe the bore and plate edge with the ignition off.

Common hints the TPS or throttle body is playing up include a check engine light, rough or hunting idle, flat spots, sudden reduced‑power/limp mode, poor fuel economy, or codes such as P0121–P0123, P0220–P0223, or P2135. If diagnostics confirm faulty internal sensor tracks, the fix is typically to replace the complete throttle body/actuator rather than the sensor alone.

• Use OEM‑quality parts and a new gasket where applicable.
• Inspect and tidy up wiring and connectors, look for oil or moisture ingress.
• After fitting, perform a throttle/idle learn. Many Captiva 7 models can self‑learn by key‑on (engine off) for ~30 seconds, key‑off for ~30 seconds, then start and let idle. A scan tool relearn is preferred.
• On diesels, consider EGR and intake cleaning at the same time to prevent repeat faults.

Handled this way, the Captiva 7’s throttle position sensors keep the drivability crisp and reliable, whether it’s the school run or a long Kiwi or Aussie highway haul.

Popular questions

How do you know the TPS is failing on a Captiva 7?
Typical signs are a check engine light, surging or stalling at idle, sluggish throttle response, and limp mode. Scan tool faults like P0121–P0123 or P2135 are common clues, and live data will show mismatched pedal vs throttle angle.

Can you replace just the TPS, or is it the whole throttle body?
On the 2013 Captiva 7, the TPS is built into the electronic throttle body (petrol) or throttle actuator (diesel). It’s not a separate service item, so replacement normally means swapping the complete unit and performing a throttle learn.

Does the diesel Captiva 7 actually have a throttle sensor?
Yes. While diesels don’t meter air the same way as petrols, the Captiva’s 2.2‑litre diesel uses an intake throttle valve with a position sensor for EGR control and smooth engine shutdown, and the ECM monitors its position just like a petrol TPS.
