Parts for your 2011 Suzuki Splash-Throttle position sensors

2011 Suzuki Splash throttle position sensor (TPS)

Based on Suzuki workshop literature for the K10B/K12B petrol engines used in the 2011 Splash, plus Autodata wiring/diagnostic references and the related Opel/Vauxhall Agila B technical docs, this model does use a throttle position sensor. It’s integrated into the electronic throttle body as a dual-track sensor that reports throttle plate angle to the engine control module (ECM). The 1.3 DDiS diesel variant also uses a throttle valve assembly with position feedback. So yes—on a 2011 Suzuki Splash, a TPS is relevant and fitted.

On this Splash, the TPS tells the ECM exactly how far the throttle blade is opened, so fuel and ignition can be trimmed to match driver demand. The sensor is typically a non-contact or potentiometer-style dual sensor for redundancy, ensuring the ECM can cross-check both signals. If either track goes out of range, the car may drop into limp mode to keep things safe.

For servicing, the TPS itself isn’t a regular replacement item, but keeping the throttle body clean and the harness/connectors tidy goes a long way. Dust, oil vapour and carbon can make the throttle plate sticky, which the ECM can misinterpret as a sensor issue. When cleaning, use a proper throttle-body cleaner and avoid flooding the electronics. After cleaning or battery disconnection, a throttle/idle learn may be needed—some vehicles relearn with a simple key-on wait and short drive, others prefer a scan-tool routine. A workshop with Suzuki-capable diagnostics can run the adaptation in a few minutes.

• Common symptoms of TPS trouble: erratic idle, flat spots on acceleration, sudden throttle cut, high fuel use, or a MIL with codes like P0120–P0124 or P2135.
• If replacement is needed, choose a quality throttle body/TPS assembly (many are supplied as one unit). Check the connector pins for corrosion, fit a fresh gasket if removed, and torque fasteners evenly to avoid air leaks.
• After fitting, perform a throttle relearn and clear codes. A short drive cycle with gentle acceleration through the rev range usually helps the ECM settle trims.

With reliable TPS feedback, the Splash runs smoother, uses less fuel, and responds crisply to the right foot—exactly what’s wanted for city runs and weekend kilometres alike.

Popular questions

Where is the TPS on a 2011 Suzuki Splash?
The TPS is built into the electronic throttle body, mounted on the intake side of the engine. On K10B/K12B petrol engines, it’s part of the round throttle housing where the air duct connects. It isn’t a separate external sensor on most Splash petrol variants.

Does the TPS need calibration after replacement or cleaning?
Yes, a throttle/idle learn is recommended after cleaning the throttle body or replacing the throttle body/TPS assembly. Many cars relearn automatically after key-on and a short drive, but using a scan tool to run the throttle adaptation is the most reliable method.

What faults can mimic a bad TPS?
Air leaks (split intake hose, loose clamps), a dirty throttle bore, poor battery voltage, or a damaged connector can trigger similar symptoms and codes. Always rule out vacuum leaks and wiring issues before condemning the TPS.
