Parts for your 2007 Nissan Dualis-Throttle position sensors

2007 Nissan Dualis throttle position sensor (TPS)

For the 2007 Nissan Dualis (J10, MR20DE), a throttle position sensor is very much in play. Technical references including Nissan’s J10 Electronic Service Manual (Engine Control System for MR20DE) specify an electronic throttle body (drive‑by‑wire) that incorporates dual throttle position sensors within the throttle actuator. These are not serviced separately from the throttle body assembly. Industry data services (e.g., Autodata/Alldata) also list TPS‑related diagnostics (such as P0120–P0124) for this model, confirming its presence and role.

On this Dualis, the TPS tracks how far the throttle plate is opened and sends that position to the engine control module. Alongside the accelerator pedal position sensors, it allows the ECU to match driver demand with smooth, controlled throttle movement, stable idle and clean shifts. Because it’s integrated, a failing TPS usually means replacing the complete throttle body rather than just the sensor.

As part of routine servicing, it’s smart to check for any stored fault codes and monitor throttle angle data with a scan tool. If idle is hunting, there’s a flat spot on take‑off, or the check engine light’s on with a TPS code, attention is due. Many drivability niggles on these can be from a dirty throttle plate rather than the sensor itself. A careful clean of the throttle bore and plate using throttle body cleaner (don’t soak electronics) often sorts rough idle or hesitation.

After cleaning or replacement, the Dualis typically needs a throttle/idle relearn so the ECU knows the new closed and idle positions. Nissan documents three key procedures: accelerator pedal released position learning, throttle valve closed position learning and idle air volume learning. A capable scan tool can run these quickly, some can be done with a timed pedal/ignition sequence if a scan tool isn’t available.

If the throttle body does need replacing, expect to transfer the gasket if required, torque the mounting bolts evenly, and visually inspect the harness and connector for corrosion or broken wiring. It’s also wise to check battery health and grounds—low system voltage can trigger TPS‑related codes. With clean air intake plumbing, good electricals and the relearn done, the 2007 Dualis usually returns to a smooth, predictable throttle feel and consistent fuel economy.

• Common symptoms of TPS/throttle body issues: erratic idle, poor throttle response, stalling when coming to a stop, and the MIL on with TPS codes.
• Service tip: schedule a throttle body clean around every 40–60,000 kilometres, especially if most driving is around town.

Does a 2007 Nissan Dualis have a separate TPS I can swap?

No. On the J10 Dualis the TPS is built into the electronic throttle body as dual tracks. If the sensor fails, the fix is to replace the whole throttle body assembly, then perform the relearn procedures.

What are the signs the TPS/throttle body is playing up on a 2007 Dualis?

Expect rough or high idle, hesitation off the line, surging at steady speed, and a check engine light. Scan data often shows mismatched or erratic throttle angles, and fault codes like P0120–P0124 may be stored.

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

Yes. Nissan specifies throttle/idle relearn steps after cleaning or replacement. A scan tool makes it quick, without one, use the documented pedal/ignition timing procedures to teach the ECU the new closed and idle positions.
