Parts for your 2008 Nissan Tiida-Throttle position sensors

2008 Nissan Tiida Throttle Position Sensor (TPS)

Yes, the 2008 Nissan Tiida uses a throttle position sensor. Technical references including the Nissan Tiida/Versa C11 Factory Service Manual (EC – Engine Control, Electronic Throttle Control System) and mainstream service databases such as Autodata and ALLDATA note that the Tiida’s electronic throttle body houses the throttle position sensor(s) as part of the throttle actuator control assembly. It’s not a separate, cable-era bolt-on switch, it’s integrated into the electronic throttle body alongside the motor and is monitored together with the accelerator pedal position sensor.

On a 2008 Tiida, the TPS tells the engine computer exactly how far the throttle plate is open, so fuel delivery, ignition timing and idle control can be spot-on. Because it’s built into the throttle body, it’s designed for accuracy and reliability with redundancy inside the unit. If the readings don’t tally with the pedal sensor or expected values, the ECU will throw a code and may drop the car into limp-home to protect the driveline.

When it comes to servicing, there’s no separate TPS to adjust. If drivability issues pop up—like surging, hesitant take-off, erratic idle, stalling at lights, or the MIL on with codes such as P0121, P0122, P0123, P0221 or P2135—start with the basics: clean the throttle body, check the harness and connector for corrosion, and verify power/earth and reference voltages. After cleaning or battery disconnection, perform the Nissan relearn procedures (throttle valve closed position, accelerator released position, and idle air volume learn). A capable scan tool makes this far easier and more reliable than timing it by pedal.

• If the TPS signal is faulty and non-recoverable, the fix is typically a complete throttle body replacement (new gasket recommended). The sensor isn’t serviced separately.
• Use quality parts and ensure no vacuum leaks on reassembly. Clear codes and run the throttle/idle relearns so the ECU can park the blade correctly at idle.
• Preventive care: keep the intake tract clean, use good fuel, and inspect the connector during routine servicing. Many “TPS faults” are actually dirty throttle plates or poor earths.

Done right, the Tiida’s throttle control is set-and-forget for many kilometres, delivering smooth take-up and tidy fuel economy under the bonnet.

Popular questions about 2008 Nissan Tiida throttle position sensors

Where is the throttle position sensor on a 2008 Nissan Tiida?
The TPS is integrated into the electronic throttle body on the intake manifold. It isn’t a separate external sensor. The unit combines the throttle motor and dual-position sensors, all managed by the engine control module.

This design supports the Tiida’s drive-by-wire system and removes the need for periodic TPS adjustment.

Can the TPS be replaced on its own, or is a full throttle body needed?
On this model, the TPS is not sold as a standalone item. If the TPS fails testing after wiring and connector checks, the repair is to replace the throttle body assembly.

After fitting, a throttle/idle relearn is required so the ECU can correctly calibrate the new unit.

Do relearn procedures need to be done after cleaning or battery disconnection?
Yes, it’s good practice. Perform throttle valve closed position learning, accelerator released position learning, and idle air volume learn. Many scan tools can automate this, the pedal-timing method can work but is fussier.

Skipping relearns can leave the Tiida with a high or unstable idle and delayed throttle response.
