Parts for your 2016 Nissan Navara-Throttle position sensors

2016 Nissan Navara throttle-position-sensor: what it is, how it works, and when to service it

Based on technical references including the Nissan Navara D23 (NP300) Service Manual – Engine Control (EC) section and common OEM supplier data on electronic throttle control, the 2016 Navara doesn’t use a separate, old-school, cable-era throttle position sensor (TPS). Instead, both the diesel YS23 variants (common in AU/NZ) and any market petrol variants run drive-by-wire: an accelerator pedal position (APP) sensor at the pedal and an electronically controlled throttle/air valve that incorporates its own position sensor inside the actuator. So the TPS function is absolutely used, but it’s built into the throttle body or throttle control valve rather than being a standalone bolt-on sensor.

On the 2016 Navara, the TPS’s job is to tell the engine control module exactly where the throttle plate (or intake air valve on the diesel) sits at any moment. Together with the pedal sensor, it lets the ECU match driver demand to airflow, fuel, EGR and emissions control. As outlined in Nissan’s EC section for D23, this closed-loop arrangement improves response, idle stability and shutdown smoothness on the diesel by briefly modulating the intake throttle.

When it comes to servicing, the TPS isn’t usually a separate replacement item. On most 2016 Navara variants it’s integrated into the throttle body/throttle control valve, faults typically require replacing the complete assembly. After replacement, a throttle/idle “learning” procedure via scan tool is recommended so the ECU knows the new sensor’s exact closed and open positions.

• Common clues of a TPS/throttle control issue: uneven idle, limp-home mode, hesitation, poor cruise control behaviour, or fault codes for throttle/pedal correlation.
• Basic checks first: battery health and grounds, throttle body connector condition, and intake cleanliness under the bonnet.
• Cleaning: on petrol units, careful throttle bore cleaning can help sticky response, never force the blade. On diesel intake throttles, inspect for carbon build-up but avoid drowning the actuator.
• Calibration: perform throttle closed-position and idle air volume learning after any throttle body or ECU work.

Technicians generally verify operation with live data (tracking pedal vs. throttle angles) and correlation tests. If the position signal is noisy or outside expected range, or if the actuator fails self-tests, replacement of the assembly is the reliable fix. Using genuine-calibre parts and keeping connectors dry and secure tends to keep the Navara happy for many kilometres.

Popular questions about 2016 Nissan Navara throttle-position-sensors

Does a 2016 Nissan Navara have a TPS?
Yes—functionally it does. The TPS is integrated into the electronic throttle body or diesel throttle control valve, and works alongside the accelerator pedal position sensor. There isn’t a separate, screw-on sensor like older cable-throttle setups.

Can the TPS be replaced on its own?
On most D23 Navara variants, no. The TPS is part of the throttle/air valve assembly and isn’t serviced separately. If the position signal or actuator is faulty, the usual remedy is replacing the complete unit, followed by a throttle/idle learn procedure.

What symptoms point to a failing TPS on a Navara?
Drivers may notice erratic idle, sluggish response, intermittent limp-home, or cruise control dropping out. Scan tools often show throttle/pedal correlation faults or position range performance codes. Checking power/earths and the connector first can save time before calling the throttle assembly.
