Circuit Description

When output signal from output shaft speed sensor multiplied by reverse gear ratio is not the same as output signal from input shaft speed sensor after shifting to Reverse, DTC 46 is set. When DTC 46 is set 4 times, transaxle is locked into 3rd gear as a fail-safe measure and "N" range indicator light flashes. Possible cause for DTC 46 may be faulty input shaft speed sensor, output shaft speed sensor, PCM, underdrive clutch retainer, output shaft, low-reverse brake system, reverse clutch system, or noise interference in harnesses or connectors.
