This guide is intended to cover test procedures applicable to MAP transducers; it is also applicable to transducers such as Barometric (Ambient) Absolute Pressure transducers, Manifold Vacuum transducers, and similar pressure transducers used in automotive systems. Although oriented towards active devices (those using internal signal conditioning), it can be applied to passive devices with minor modifications.

The scope of this document is to provide uniform guidelines for the application of starter motor pinions and ring gears. SAE J543 contains guidelines for the use of diametral pitch gearing. The pinion data shown are based on the Fellows stub tooth system. Refer to ISO 8123, ISO 9457-1, and ISO 9457-2 for module gearing, and corresponding metric dimensions.
