Description:
The throttle position switch (TPS) is the switch on the side of the throttle body that tells the ECU whether the throttle body is open or closed (idle). The original TPS units commonly build up corrosion both on the connector and between the contacts under the cover. The contacts can also wear out in some very high mileage cases. These issues can result in situations where either too much (flooding) or too little (starvation) fuel is sent to the engine, resulting in surging, roughness, stalling, or even fuel cut-off ("coast" mode, which should only be active when decelerating at higher RPMs). This is the genuine, original equipment (OEM) throttle position switch, which is located on the side of the throttle body.

Supercessions:
This part number is 'superceded'. Most of our supercessions originated with Nissan. A part made for a Z31, for instance, may actually be the same as the part made for the Z32, but it was given a different number. Nissan would then later supercede the number, so that if you ordered the part number for the Z32, what you would actually get is the original part number for the Z31 (or vice-versa), as they are the same part. Other times, supercessions can exist between different parts on the same car, as is often the case with hardware of the same size. These supercessions were Nissan decisions, where replacing the 'superceded from' part with the 'superceded to' part results in identical performance. The vast majority of them are simple numbering changes, where the parts are literally identical. In some cases, the two parts are identical in fit and function, but the finish is slightly different, or the non-critical overall dimensions are slightly different (like one starter housing being '' shorter than the other on the non-attached side). They do not affect the function of the part, and in many cases, the 'superceded-to' part improves upon the 'superceded-from' part.
