Parts for your 2019 Suzuki Splash-Throttle position sensors

2019 Suzuki Splash throttle-position-sensors

Based on factory service information for the Suzuki Splash/Opel Agila B platform (K10B/K12B engines), the Maruti Suzuki Ritz workshop manual (the Indian-market twin of Splash), and general OEM EFI guidance used in Autodata, the Splash uses a throttle position sensor (TPS). On most variants it’s integrated into the electronic throttle body (drive‑by‑wire) with dual sensor tracks for redundancy, so the TPS is absolutely relevant and fitted to a 2019‑registered Splash.

What does it do? The TPS constantly reports the throttle plate angle to the engine control module. That signal is key for fuelling, ignition timing, idle speed strategy, decel fuel cut, and—where applicable—auto transmission shift logic and cruise control behaviour. In short, it helps the Splash feel smooth off the line, responsive in traffic, and efficient on petrol.

Common signs the TPS or throttle body is unhappy include:

• Hesitation, flat spots, or surging on light throttle
• High or hunting idle, stalling when coming to a stop
• Poor fuel economy and a glowing MIL/engine light (often codes like P0120–P0123, P0220 range/performance)
• Limp-home mode and limited throttle response

Servicing advice for a Splash’s TPS/throttle body:

• At 20,000–40,000 km intervals, have the throttle body inspected and cleaned. Carbon build-up around the throttle plate can mimic TPS faults.
• Check for vacuum leaks and brittle hoses—unmetered air skews TPS/airflow correlation.
• Scan live data: the two TPS tracks should rise smoothly and agree. Any dropouts or mismatched signals point to a failing unit or wiring.

Replacement considerations: on most drive‑by‑wire Splash models, the TPS is not sold separately, the entire throttle body is replaced. Expect roughly 0.8–1.5 hours of labour. After fitment, a throttle/idle learn procedure with a scan tool is recommended so the ECU relearns end‑stops. Always inspect and, if needed, clean the intake before first start, clear fault codes, and verify there’s a stable 5 V reference and good grounds at the connector. If yours is an earlier cable‑throttle variant where the TPS is a bolt‑on sensor, it can be swapped individually, set the sensor so closed‑throttle voltage sits within spec per service data, then confirm a smooth sweep with no dead spots. Keeping connectors clean and dry, using quality fuel, and staying on top of scheduled servicing will help the Splash’s TPS do its job for the long haul under Aussie and Kiwi conditions.

Popular questions about 2019 Suzuki Splash throttle-position-sensors

Does the 2019 Suzuki Splash actually have a TPS?
Yes. Manufacturer service data for the Splash/Agila B and the Maruti Ritz manuals specify an electronic throttle body that contains dual throttle position sensors. It’s a standard component of the fuel‑injection and throttle control system.

Do I need to programme anything after replacing the TPS/throttle body?
On drive‑by‑wire Splash models, perform a throttle/idle relearn with a scan tool after replacement or cleaning. This lets the ECU relearn throttle end‑stops and idle airflow. Skipping this step can leave the idle high or cause a hesitant tip‑in.

Can cleaning fix TPS‑type symptoms?
Often, yes. Carbon around the throttle plate can cause erratic airflow that looks like a TPS fault. A careful throttle body clean, checking for vacuum leaks, and verifying wiring can restore smooth running before any parts are replaced.
