Circuit Description

DTC P1794 will set after a PCM reset in Neutral, and input RPM and output RPM equals a ratio of input to output of 2.50:1. Transaxle will not go into limp-in mode until 3 gear ratio error events occur in a given key start. MIL will illuminate after 5 minutes of substituted operation. This allows for intermittent problems to correct themselves without opening relay. However, if a gear ratio error develops, a DTC is always set, but if condition corrects itself, transaxle will continue without requiring ignition key to be cycled off and on.
