2011 Suzuki Splash throttle position sensor (TPS): what it does and how to look after it

Technical sources indicate the 2011 Suzuki Splash is fitted with a throttle position sensor. The Suzuki Workshop Manual for K10B/K12B engines (Engine Control System section) details an electronic throttle body with an integrated dual-track TPS used for throttle angle feedback and diagnostics (DTCs P0120–P0124). Suzuki’s Electronic Parts Catalogue for 2011 Splash lists a complete throttle body assembly that incorporates the TPS, and the ECM diagnostic charts reference throttle position data as a primary input. So, a throttlepositionsensors is relevant and used on this model.

On the 2011 Suzuki Splash, the throttle position sensor sits inside the electronic throttle body and constantly reports the throttle plate angle to the engine control module. That signal is crucial for fuelling, spark timing, idle control, cruise control behaviour and emissions. Because it’s a drive-by-wire setup, the Splash uses dual TPS tracks to cross-check signals for safety, if the signals disagree, the car can drop into limp mode and light the check engine lamp.

As part of regular servicing, it pays to keep the throttle body clean and the TPS connector healthy. Dust, oil vapour and carbon can build up around the throttle plate, upsetting the reported angle and idle airflow. A careful throttle body clean (battery off, use proper throttle cleaner, don’t force the plate by hand) often restores crisp response and smooth idle. Inspect the wiring loom for chafe, make sure the connector is seated, and look for any green crust on pins, a quick contact clean and dielectric grease can prevent intermittent faults, especially in wet Kiwi and Aussie conditions.

When faults persist—like erratic idle, hesitation off the line, surging at steady speed, or codes P0120–P0124—the fix on a Splash is typically to replace the throttle body assembly, as the throttlepositionsensors is integrated and not meant to be serviced separately. After replacement, a throttle/idle relearn is recommended. Many scan tools offer a “throttle learn” or “idle learn” function, otherwise, allow the engine to reach operating temperature, then let it idle with all accessories off for several minutes so the ECU can relearn the closed position and airflow. If the light stays on, clear codes and check live data: throttle angle should move smoothly from closed to wide-open with no sudden jumps.

• Service tip: clean the throttle body every 30,000–40,000 km.
• Avoid water ingress at the connector after engine bay washes.
• If replacing, use a quality gasket and follow torque guidance from the workshop manual.

Popular question: Where is the throttle position sensor on a 2011 Suzuki Splash?

It’s built into the electronic throttle body mounted on the intake manifold, right where the air intake duct meets the engine. You’ll see a multi-pin connector on the throttle body—this carries the TPS and throttle motor signals.

Popular question: What are common symptoms of a faulty TPS on a Splash?

Drivers often notice a hunting or high idle, flat spots on tip-in, poor fuel economy, or the car dropping into limp mode. The check engine lamp may illuminate with codes like P0120–P0124, and live data will show erratic throttle angle changes that don’t match pedal input.

Popular question: Does the TPS need calibration after replacement?

Yes—because it’s part of the throttle body, a throttle/idle relearn helps the ECU store the correct closed and part-open positions. Use a scan tool’s relearn procedure if available, or let the engine warm fully and idle with all loads off for several minutes, then take a gentle drive so the ECU adapts.
