For help with diagnostic testing. See WIRING DIAGRAMS. NOTE: The throttle valve position output signal can be used as a load signal for other control modules (e.g. for the automatic transmission). Perform the following check ONLY if the output signal is actually used for another control module. Currently, this signal is output, but not used.
