Topfactory Throttle Position Sensor: Compatible with multiple Nissan models
Available Options
Ever wonder what keeps your engine from coughing and sputtering like a bad cold? Meet the Throttle Position Sensor—the unsung hero under the hood. This little gadget monitors the throttle valve's every move, feeding real-time data to the engine's brain, the ECU. The result? Pinpoint fuel injection and ignition timing that squeeze out every drop of performance, boost fuel economy, and keep emissions in check.
In workhorses like the Nissan Frontier, Pathfinder, and Xterra from the late '90s to early 2000s, a healthy sensor is your best defense against rough idling, sluggish acceleration, or that dreaded stall. Think of it as the engine's personal trainer: when it's on point, everything runs smooth; when it fails, you get hesitation and power dips that'll ruin your drive. Swapping it out is a breeze with basic tools—a quick fix for DIYers or pros aiming to keep their ride reliable, whether you're battling city traffic or tackling rugged trails.

Throttle Position Sensor

I had to replace this in my old Nissan because the engine was acting up—coughing and sputtering like crazy, especially when I'm driving the kids around. It was quite frustrating and made me unhappy, but this sensor from Topfactory did the trick. Compared to other options I looked at, this one seems reliable and easy to install. Now the car feels like it's back to its best, no more power dips or rough rides. :) Definitely a good buy for keeping things running without any fuss.
- Pros: It arrived quickly, and the courier called ahead which was nice. Installation was straightforward with basic tools, and it fixed my engine's rough idling and hesitation right away. The car runs much smoother now, with better acceleration and no more stalling issues.
- Cons: Nothing really bad to say, most likely it's just a basic part, but I was quite skeptical at first since it's a replacement for an old one that failed.
