Parts for your 2013 Nissan Pathfinder-Throttle position sensors

2013 Nissan Pathfinder throttle-position-sensors: what they do and how to look after them

Technical references confirm the 2013 Nissan Pathfinder (R52, VQ35DE) does use throttle-position-sensors. Nissan’s factory Service Manual (R52, EC – Electronic Throttle Control System) specifies an electronic throttle body that houses dual throttle-position-sensors, and the Nissan parts catalogue lists the throttle body as an assembly with the motor and position sensors. Nissan service procedures also call for throttle/idle learning after throttle body work, further proving the sensors are integral to the system.

On a 2013 Pathfinder, the throttle-position-sensors (TPS) live inside the electronic throttle body. Their job is to tell the engine computer exactly how far the throttle plate is open, so fuelling, ignition timing and the CVT’s shift logic all stay smooth and efficient. That accurate feedback helps with crisp throttle response, stable idle and better fuel economy on long Kiwi and Aussie drives.

Worth knowing: the TPS isn’t a separate bolt-on part for this model. If the sensor fails, the fix is to replace the complete throttle body assembly. After fitting, a technician must carry out the throttle/idle relearn procedures using a capable scan tool, otherwise idle can be unstable or the car can drop into limp mode. It’s a tidy job under the bonnet—intake duct off, electrical connector and coolant hoses (if equipped) managed, then the body comes off the manifold. New gasket on, refit, and tighten the bolts to factory spec.

Preventative care is simple. Every 60,000–100,000 kilometres, have the throttle bore inspected and gently cleaned with a sensor-safe throttle cleaner. Don’t force the plate open by hand, and avoid soaking the electronics. Good battery voltage and clean engine grounds also help keep the electronic throttle happy. If the Pathfinder shows a rough idle, sluggish take-off, surging, higher-than-usual fuel use, or throws codes like P0121/P0122/P0123 or P2135, get it scanned—those are classic signs the system isn’t reading throttle angle cleanly.

Bottom line: the 2013 Pathfinder definitely relies on its throttle-position-sensors, and while they’re built into the throttle body, a bit of routine cleaning and proper relearn after any work keeps the big Nissan running sweet.

FAQs

Does a 2013 Nissan Pathfinder have a throttle-position-sensor?
Yes. It uses an electronic throttle body with built-in throttle-position-sensors (typically dual-track) as part of the Electronic Throttle Control system.

Can the throttle-position-sensor be replaced on its own?
No. On the 2013 Pathfinder the TPS is integrated into the throttle body. If the sensor fails, the complete throttle body assembly is replaced, followed by throttle/idle relearn with a scan tool.

What are common signs or fault codes of a TPS issue on this model?
Drivers may notice rough idle, hesitation, limp mode, or poor fuel economy. Common related DTCs include P0121–P0123 and P2135. A proper diagnostic scan under the bonnet will confirm whether it’s the throttle body, wiring, or something else.
