Parts for your 2015 Nissan Navara-Throttle position sensors

2015 Nissan Navara throttle position sensors

Based on technical references, the 2015 Nissan Navara (D23/NP300) does use a throttle position sensor. The Nissan Electronic Service Manual for D23 (EC section) describes an electronic throttle system, and for the 2.3-litre diesel (YS23) engines it lists an intake throttle/air volume control valve with a built-in position sensor for feedback to the ECM. Autodata’s coverage of the D23 and Bosch EDC17 diesel management documentation also note an electronically controlled throttle valve with position sensing for EGR blending and engine shutdown. Petrol variants (QR25DE) use an electronic throttle body with an integrated throttle position sensor as well.

On a 2015 Navara, the throttle position sensor (TPS) is built into the throttle body (petrol) or the intake throttle/air volume control actuator (diesel). Its job is to tell the engine computer exactly how far the throttle plate is open so fuelling, boost control, EGR flow and idle speed can be managed smoothly. That feedback keeps throttle response crisp, helps the auto shift more cleanly, supports cruise control, and on diesels it also aids EGR operation, DPF strategies and a gentle engine shutdown.

There’s no fixed replacement interval for the TPS on this model, but it’s smart to have it checked during routine servicing. A quick scan of live data to confirm consistent throttle angle, a look for stored fault codes, and a visual once-over of the connector and loom near the throttle housing can save a headache later. Common clues of trouble include a lazy pedal feel, surging, poor idle, limp-home, higher fuel use, and an engine light with codes like P0120–P0123, P2135 or P2101.

On petrol Navaras, cleaning carbon from the throttle plate with proper throttle cleaner can help drivability, don’t flood the electronics and don’t force the plate. On the 2.3 diesel, avoid forcing the intake throttle flap by hand, if it’s sticky, remove the unit and clean the bore carefully, keeping solvent away from the sealed sensor and motor. If the sensor goes faulty, it’s typically replaced as part of the whole throttle body/actuator assembly rather than as a separate piece. Use a quality unit, fit a new gasket, torque the bolts correctly, and complete throttle-related learning procedures (closed-position and accelerator released-position learning) with a capable scan tool or Nissan Consult. After any work, clear codes and confirm the throttle angle tracks smoothly from closed to wide-open under the bonnet and on a road test.

• Typical symptoms: uneven idle, flat spots, hesitation, harsh shutdown on diesel, limp mode, and relevant DTCs.
• Good practice: inspect every 20,000 km, keep connectors clean and clipped, and verify throttle learns after battery or part replacement.

Popular questions about 2015 Nissan Navara throttle position sensors

Does a 2015 Nissan Navara actually have a throttle position sensor?
Yes. The D23 platform uses electronic throttle control. Petrol models have a TPS integrated into the throttle body, while the 2.3-litre diesel uses an intake throttle (air volume control) with a built-in position sensor that the ECM monitors for EGR and shutdown control, as outlined in Nissan’s D23 service manual and mainstream workshop data.

Where is the TPS located on a 2015 Navara?
On petrol variants, it’s inside the electronic throttle body at the front of the intake manifold. On the 2.3 diesel, it’s part of the intake throttle/air volume control unit near the EGR mixer on the inlet side. Note this is separate from the accelerator pedal position sensor mounted on the pedal assembly.

Can the TPS be cleaned, or does it need replacing?
The sensor itself is sealed and not serviceable. Cleaning targets carbon on the throttle plate and bore, which can help drivability if they’re dirty. If the sensor circuit is faulty or readings are erratic, the usual fix is replacing the complete throttle body/actuator. After replacement, perform throttle/accelerator relearn procedures and verify smooth, linear throttle angle on a scan tool.
