Parts for your 2004 Nissan Tiida-Throttle position sensors

2004 Nissan Tiida throttle position sensors (TPS) — what they do and how to look after them

Technical references confirm that the 2004 Nissan Tiida (C11 series) is fitted with throttle position sensors. The Nissan factory service manual for the Tiida/Versa C11 platform (EC: Engine Control System, Throttle Control System) describes an Electric Throttle Control Actuator that houses dual throttle position sensors integrated into the throttle body, along with the throttle control motor. Nissan’s parts catalog for C11 likewise lists the throttle body assembly as the serviceable unit, not a standalone TPS.

On a 2004 Tiida, the TPS units sit inside the electronic throttle body and constantly report the throttle plate angle to the engine control module. That live feedback helps the ECU juggle fuel, spark and idle control for smooth take-offs, steady cruising and decent fuel economy. Because they’re integral (and there are typically two sensors for redundancy), the car can cross-check signals for safety and limp-home strategies if something goes off.

In day-to-day servicing, there’s no separate TPS to adjust. If the sensors fail, the fix is to replace the complete electronic throttle body assembly. After fitting, the ECU needs its learning procedures done — throttle valve closed position learning and idle air volume learning — with a capable scan tool or the factory key-on/key-off method as outlined in the Nissan EC section. Skipping those steps can leave the Tiida idling rough or stalling at lights.

Good maintenance helps the TPS live a long life. Every 50–80,000 kilometres, it’s worth removing the intake duct and carefully cleaning the throttle bore and plate with throttle-body-safe cleaner. Don’t force the plate open by hand and don’t soak the electronics. Check the connector for green corrosion, make sure the battery and engine grounds are tidy, and never tweak the throttle stop screw. If the MIL’s on and it’s surging, hesitating or stuck in limp with codes like P0120–P0123 or P2135, it’s time for proper diagnostics — verify power, ground, signal plausibility and wiring before condemning the throttle body.

When replacement is needed, choose a quality unit, fit a new gasket, torque to spec, clear codes and complete the learning procedures. Done right, the Tiida will idle cleanly and respond crisply under the bonnet for many more kilometres.

• Common signs: erratic idle, delayed throttle, poor fuel economy, MIL on
• Service tip: always perform throttle and idle relearns after work

Popular questions

Does a 2004 Nissan Tiida have a throttle position sensor?
Yes. Per the Nissan C11 factory service manual (EC/Throttle Control System), the 2004 Tiida uses an electric throttle body with dual, built-in throttle position sensors. They’re part of the throttle body assembly and provide continuous angle feedback to the ECU.

Can the TPS be replaced separately on a 2004 Tiida?
No. The TPS is integrated into the electronic throttle body and isn’t a separate service item. If the TPS fails testing, the correct repair is to replace the throttle body assembly, then carry out the throttle closed-position and idle air volume learning procedures.

What are the symptoms of a faulty TPS on a Tiida?
Owners may notice unstable idle, hesitation, flat spots, reduced power or limp mode. The check engine light often logs codes such as P0120–P0123 or P2135. Before replacing parts, confirm power, ground and signal integrity and rule out throttle bore contamination.
