Parts for your 2016 Suzuki Splash-Throttle position sensors

2016 Suzuki Splash throttle-position-sensors

Technical sources confirm the 2016 Suzuki Splash uses a throttle position sensor (TPS). The Suzuki Splash/Agila B Service Manual (K10B/K12B) under Engine Control System lists a dual-track TP sensor integrated into the electronic throttle body, with related DTCs P0120–P0124. This is mirrored in Suzuki Swift (K12B) workshop documentation—same K-series family—showing the TP sensor as part of the throttle body assembly and not serviced separately. Autodata/HaynesPro listings for Splash/Agila also show TP sensor monitoring and correlation checks with the accelerator pedal position (APP) sensor.

The TPS on a 2016 Suzuki Splash is there to tell the engine control module exactly how far the throttle plate is open. Because the K-series engines run drive-by-wire, the TPS is built into the throttle body and works in tandem with the accelerator pedal position sensor. Together they manage fuel delivery, ignition timing and idle control, and they keep emissions in check while making the car feel smooth around town. If the TPS signal drifts or drops out, the ECM will flag a fault, pop the MIL on, and often drop the car into limp mode to protect the engine.

Servicing is straightforward but a bit specific on these. The TPS is not sold separately from the throttle body by Suzuki, so replacement typically means swapping the entire throttle body assembly. Before getting the spanners out, a quick check with a scan tool can save time—look at TP1/TP2 live data and correlation, and confirm any DTCs like P0122, P0123, P0222 or P0223. If the throttle body is replaced or removed for cleaning, plan on an idle relearn with a capable scan tool, some cars will relearn after a few key cycles and steady idle, but it’s best to follow manufacturer procedures for a stable tick-over.

• Common symptoms: erratic idle, flat spots on take-off, poor fuel economy, MIL on, or limp-home behaviour.
• Maintenance tip: avoid soaking the throttle shaft with harsh cleaners, use throttle-body-safe spray and keep electronics dry.
• When to act: persistent DTCs, obvious wear, water ingress, or binding throttle plate call for replacement rather than endless cleaning.

Quality parts and a clean gasket seal are key. After installation, verify throttle angle, idle speed and APP/TPS correlation with a scan tool, take it for a gentle drive, and you’re good as gold.

FAQs

Does the 2016 Suzuki Splash have a separate throttle position sensor or is it built into the throttle body?
It’s integrated into the electronic throttle body. Suzuki’s service information for the K10B/K12B engines shows the TP sensor as part of the throttle body assembly, with dual sensor tracks for redundancy, so it isn’t normally replaced on its own.

What are the signs the TPS on a Splash is playing up?
Look for a check engine light, rough or high idle, hesitation on light throttle, poor fuel economy, or the car dropping into limp mode. A scan tool will usually reveal TP-related DTCs and mismatched readings between the TPS and the accelerator pedal sensor.

Can cleaning fix TPS issues on this model?
Light cleaning of the throttle plate and bore can help sticky idle, but it won’t repair a failing internal sensor. If faults persist after cleaning and an idle relearn, the cure is generally a new throttle body assembly.
