2006 Nissan Tiida throttle position sensor: what it is and how to look after it

Technical conclusion: The 2006 Nissan Tiida (C11 series, HR and MR petrol engines) does use a throttle position sensor. Per the Nissan C11 Factory Service Manual (EC and Accelerator Control System sections, 2006) and Nissan’s Electronic Throttle Control System description used on the Tiida/Versa platform, the TPS function is built into the electronic throttle body (throttle control actuator) as dual position sensors. It isn’t a stand‑alone, adjustable sensor, diagnosis and service are performed via the throttle body assembly and ECU procedures (DTCs such as P0121, P0122, P0123, P2135 are defined in the FSM). Trade data sets such as Autodata/Haynes align with this architecture, noting the TPS is integral and replaced with the throttle body if faulty.

The throttle position sensor on a 2006 Nissan Tiida lives inside the electronic throttle body, tracking the throttle plate angle so the ECU can nail fuel delivery, ignition timing and idle control. It works in tandem with the accelerator pedal position sensor and uses two tracks for redundancy, so the ECU can cross‑check for accuracy and keep the drive‑by‑wire setup safe and smooth.

Because it’s integrated, there’s nothing to “adjust” on the TPS. Servicing focuses on keeping the throttle body clean and the electrical connection healthy. If the Tiida starts idling rough, feels laggy off the mark, jumps into limp mode, or logs codes like P0121, P0122, P0123, P2101 or P2135, it’s time for a proper check.

Good maintenance under the bonnet goes a long way. Every 20,000–30,000 kilometres (more often if it sees dusty city driving), it’s worth inspecting and carefully cleaning the throttle bore and plate. Don’t force the plate open by hand and avoid harsh solvents that can strip any protective coating—use a throttle‑safe cleaner and a lint‑free cloth. Make sure the TPS/actuator connector is clean, pins are snug, and engine earths are solid. Also rule out vacuum leaks and a sticky accelerator pedal before condemning the throttle body.

If the sensor proves faulty, the fix is to replace the throttle body assembly with a new gasket. After any cleaning or replacement, the Tiida needs the learning procedures: Accelerator Pedal Released Position Learning, Throttle Valve Closed Position Learning and Idle Air Volume Learning. A scan tool (CONSULT‑III or equivalent) is the simplest way, but the manual method from Nissan service literature also works if followed closely. Do it with a fully charged battery and a warm engine to avoid a high idle or hunting behaviour afterwards.

Owners and techs will notice that when the TPS is happy, the Tiida’s throttle response is crisp, idle is steady, fuel economy is consistent, and the auto (where fitted) shifts predictably. When it’s not, the ECU will tell you—so don’t ignore that MIL.

Does the 2006 Nissan Tiida have a separate throttle position sensor I can replace?

No. On the C11 Tiida the TPS is built into the electronic throttle body as dual sensors. If the TPS side fails testing, the remedy is to replace the throttle body assembly and perform the learning procedures noted in Nissan’s service manual.

Do I need to do a throttle relearn after cleaning or replacing the throttle body?

Yes. Perform Accelerator Pedal Released Position Learning, Throttle Valve Closed Position Learning and Idle Air Volume Learning. Skipping these can leave the idle high or unstable and may set fault codes. A capable scan tool makes it straightforward.

What are common signs of a failing TPS on a 2006 Tiida?

Rough or high idle, hesitation, poor fuel economy, limp mode, and warning lights. Typical related codes include P0121, P0122, P0123, P2101 and P2135. Always check for vacuum leaks and pedal sensor issues before replacing parts.
