Parts for your 2006 Suzuki Swift-Throttle position sensors

2006 Suzuki Swift Throttle Position Sensor

Technical sources confirm the 2006 Suzuki Swift does use a throttle position sensor (TPS). The Suzuki Swift (MZ/EZ, 2005–2010) Service Manual – Engine Control System section – specifies a TP sensor integrated into the electronic throttle body on the M15A petrol engine. Autodata and common OBD diagnostics for this model also list TP/APP-related fault codes (e.g., P0120, P2135), further verifying the TPS is present and monitored by the engine control module.

On the 2006 Swift, the TPS is built into the electronic throttle body as a dual-track position sensor. Its job is to report the exact angle of the throttle plate so the ECU can juggle fuel delivery, ignition timing and throttle control for smooth take-off, stable idle and decent fuel economy. It also plays nicely with cruise control and, on autos, helps shape shift quality. Because it’s a drive-by-wire setup, accurate throttle position feedback is critical—if the readings go wonky, the ECU will often kick the car into limp mode to protect the engine.

There’s no scheduled replacement for the TPS on this model, it’s a “monitor and maintain” item. During regular services—especially around the 60,000–100,000 km marks—good practice is to:

• Scan live data to verify steady throttle angle and smooth percentage change with pedal movement.
• Check the throttle body connector for corrosion or loose pins and the loom for chafing near the intake.
• Clean the throttle bore and plate with throttle-safe cleaner to prevent sticky operation that can mimic TPS faults.

Common symptoms that point to TPS/throttle body trouble include erratic idle, hesitation, a flat spot off the mark, higher-than-usual fuel use, the ESP/traction light joining the party and a Check Engine Light with codes like P0120/P0220/P2135. If cleaning and wiring checks don’t sort it, replacement is straightforward—but note that on this Swift the TPS isn’t a separate bolt-on. The whole throttle body assembly is typically replaced.

After replacement or a battery disconnect, a throttle/idle learn procedure is required. Many shops will use a scan tool to run the adaptation. If one isn’t available, key-on cycles and a short idle stabilisation period often do the trick, but a scan tool is the tidy way to ensure the ECU knows the new closed and open positions. Finish with a road test and a fresh scan to confirm the throttle position tracks cleanly with no correlation faults.

• Tip: Use quality parts and a new throttle body gasket, and don’t overtighten the fasteners into the alloy manifold.

Popular questions

Does a 2006 Suzuki Swift have a separate, replaceable TPS?

No. On the M15A-powered 2006 Swift, the TPS is integrated into the electronic throttle body. If the sensor fails, the usual repair is to replace the entire throttle body assembly, then perform a throttle/idle learn with a scan tool.

What are the signs the TPS is failing on a 2006 Swift?

Drivers may notice rough or high idle, hesitation, flat spots on acceleration, poor fuel economy, limp mode, or the Check Engine Light. Fault codes like P0120, P0220 or P2135 are common. Always rule out a dirty throttle plate or wiring issues before condemning the sensor.

Can the TPS be cleaned or reset instead of replaced?

The sensor itself isn’t serviceable, but cleaning the throttle bore and plate can restore smooth movement and clear minor issues. After cleaning or battery disconnection, a throttle/idle relearn is recommended. If faults persist, replacement of the throttle body is the reliable fix.
