Parts for your 2014 Holden Captiva 5-Throttle position sensors

2014 Holden Captiva 5 throttle position sensor (TPS)

On the 2014 Holden Captiva 5, a throttle position sensor is absolutely used — it’s built into the electronic throttle body. GM/Holden Service Information for the Captiva/Antara platform describes an electronic throttle control system with dual throttle position sensing for redundancy, and parts catalogues from ACDelco/Delphi list a complete electronic throttle body assembly for the 2.4L petrol, noting the TPS is integrated rather than a separate bolt-on sensor. That setup is typical across late-model GM vehicles.

The TPS tells the engine control module exactly how far the throttle plate is open, so fuelling, ignition timing, and transmission shift strategy can be adjusted on the fly. On the Captiva 5’s drive‑by‑wire system, there are two (often three) position tracks inside the throttle body that cross‑check each other for accuracy. If the readings don’t agree, the ECM flags a fault and can drop the car into limp mode to protect the engine and drivetrain.

Signs the TPS/throttle body may be playing up include erratic idle, hesitation, surging, stalling when coming to a stop, poor fuel economy, or a check engine light with codes such as P0121, P0122, P0123, P0220–P0222, or P2135. Because the TPS is part of the throttle body, replacement generally means swapping the entire throttle body assembly rather than just the sensor.

As part of servicing a Captiva 5, it’s smart to inspect the air intake duct, electrical connector and wiring to the throttle body, and to clean light carbon build‑up in the throttle bore using throttle‑body-safe cleaner. Don’t force the throttle plate open by hand, use gentle cleaning with the ignition off. After cleaning or replacement, an idle/throttle relearn is recommended. Many scan tools can run the ETC learn procedure, otherwise, follow the Holden/GM SI key‑on cycles for an idle learn, and allow the engine to reach operating temperature without accessories on.

When replacement is needed, go with quality OEM‑equivalent parts. Fit a new gasket or O‑ring seal, keep the mating surfaces clean, and torque fasteners to the spec in the Holden workshop manual. After installation, clear any DTCs, perform the throttle relearn, and road‑test to confirm smooth response and stable idle. Regular air filter changes and keeping the intake sealed from dust will help the TPS and throttle body live a long, drama‑free life under the bonnet.

Does the 2014 Captiva 5 have a separate TPS I can change?

No. On this model the TPS is integrated into the electronic throttle body. If the TPS fails or the internal tracks disagree, the fix is to replace the complete throttle body assembly, then perform a throttle/idle relearn with a suitable scan tool.

What fault codes point to a TPS/throttle body issue on a Captiva 5?

Common codes include P0121–P0123 (TPS circuit range/performance/low/high), P0220–P0222 (throttle position sensor 2 faults), and P2135 (TPS 1–2 correlation). If these show up, inspect the connector and wiring first, then consider cleaning or replacing the throttle body.

Do I need a relearn after cleaning or replacing the throttle body?

Yes, a throttle/idle relearn is best practice. After cleaning, some vehicles will relearn over a few drive cycles, but using a scan tool to run the ETC or idle learn routine gives a smoother, quicker result and helps avoid high idle or stumble.
