Throttle position sensor

When you have an engine-related problem, please specify which engine you have. Wiring diagrams, parts, and systems can be very different. I found this drawing for the 1.6L. The drawing for the 2.0L is considerably different, but the TPS is in the same place on the throttle body.

I assume you mean the sensor, not the engine, right? I am not a Nissan specialist. When I have that question about parts interchangeability, I prefer to use the Rock Auto web site for reference. This works best when you have a donor car in mind that you can swipe parts from because you only have to look up the part for two vehicles. You can also go to the web sites for places like NAPA and Auto Zone, but I find them more time-consuming to navigate.

If you plan on visiting a salvage yard to find a used sensor, you will be overwhelmed with possibilities. The better alternative then is to ask one of the counter people. They have large, very expensive "Hollander Guides" for this exact purpose. It will list every part for your car with a code number. You look that number up in the back of the book and there it will list every application that used that part. I do not remember if it specifies the engine size when the parts are different between two engines. Now you have a list of models and years that can be a suitable donor vehicle, so you know exactly which ones to stop and pick through as you go hunting.

I am very familiar with older Chrysler products. On those, the same TPS was used for many years on every engine size in every car, minivan, and truck model, with a few exceptions. There were some different part numbers over the years, but they all interchanged. If a modification or improvement was made for reliability, the part got a new number or an "AA" or "AB" at the end of the number. Ford had some different throttle position sensors that had the connector re-positioned for some applications, but they would still interchange and work if the wiring harness would reach. That is nice to know only if you have a used sensor laying around and want to use it.

What problem are you trying to solve? These sensors do not cause a real lot of trouble. If you get a diagnostic fault code for low or high TPS signal voltage, there is a much better chance of finding a wiring or connector terminal problem than a problem with the sensor itself.
