Parts for your 2010 Nissan Dualis-Throttle position sensors

2010 Nissan Dualis throttle-position-sensors: what they do and how to look after them

Yes, the 2010 Nissan Dualis (J10 – also known as Qashqai in other markets) uses throttle-position-sensors, and they’re integral to the electronic throttle body. This isn’t guesswork: the Nissan Dualis/Qashqai J10 Electronic Service Manual (EC section) details an Electronic Throttle Control system with a throttle control motor and dual-track throttle-position-sensors built into the throttle body, and it lists fault codes such as P0120–P0123, P0220–P0223 and P2135 for those sensors. Nissan’s CONSULT-III/CONSULT-III Plus procedures also specify “Throttle Valve Closed Position” and “Idle Air Volume Learn” after servicing, further confirming the TPS role on this model.

On a 2010 Dualis, the throttle-position-sensors tell the engine control module exactly where the throttle plate is at any moment. That lets the ECU manage torque, idle stability, cold starts, cruise control, and even traction/ESC strategies. Because it’s a drive‑by‑wire setup, the car also has an accelerator pedal position (APP) sensor at the pedal, and the ECU cross-checks APP and TPS signals for safety and smoothness.

There’s no fixed replacement interval for the TPS because it’s part of the throttle body assembly. Sensible servicing includes checking for related fault codes, inspecting the throttle body connector and loom for corrosion or chafing, and cleaning the throttle bore and plate with a throttle‑body‑safe cleaner if there’s sticking or carbon build-up. Never force the plate open by hand. After cleaning or replacing the throttle body, carry out the throttle and idle relearn using a capable scan tool (CONSULT-III or equivalent) or the approved manual procedure, otherwise, rough idle or a high idle can persist.

Symptoms that point to TPS issues include erratic idle, hesitation on tip-in, poor fuel economy, cruise control dropouts, or the car dropping into limp mode with the MIL on. Common codes are P012x/P022x/P2135. Before replacing parts, it’s worth verifying good battery voltage, clean grounds, and an intact intake system, as low system voltage or air leaks can mimic sensor faults.

If replacement is needed, the TPS is generally not serviced separately on the Dualis, the throttle body is replaced as an assembly. Use a quality unit (OEM or reputable aftermarket), fit a new gasket, check and clean the mating surfaces, and perform the required relearn. Clearing codes and test driving to confirm stable idle and smooth throttle response rounds out the job. Many workshops in Australia and New Zealand will bundle this into a major service if drivability concerns or relevant DTCs are present.

• Key benefits of a healthy TPS on the Dualis: smoother take-off, stable idle, better fuel economy, and reliable cruise/traction performance.
• Best practice after service: throttle and idle relearn, code clear, and verification drive.

Popular questions about 2010 Nissan Dualis throttle-position-sensors

Does the 2010 Dualis have a separate TPS or is it just the pedal sensor?
It has both. The accelerator pedal has an APP sensor, and the throttle body contains dual throttle-position-sensors. The ECU compares both for accuracy and failsafe operation.

Can the TPS be replaced on its own?
On this model, the TPS is integrated into the throttle body. In most cases, the fix is to replace the complete throttle body assembly, then carry out the relearn procedures.

Do I need a relearn after cleaning or replacing the throttle body?
Yes. Perform “Throttle Valve Closed Position” and “Idle Air Volume Learn” using a suitable scan tool or the approved manual sequence. Skipping this can leave the Dualis idling too high, too low, or hunting.
