AUTOMATIC TRANSMISSION -Troubleshooting 23-22 Code No. 23 Output shaft speed sensor systemProbable cause If the output from the output shaft speed sensor is 50% or less continuously for 1 second or more while the vehicle is driving at 30 km/h or more in 4th, it is judged that there is ashort-circuit oropencircuit in the output shaft speed sensor, and code No. 23 is output. If code No. 23 is output 4 times, the transmission is locked at 3rd gear (D) or 2nd gear (downshift operation in Sports mode) as a fail-safe measure, and the N range indicator lampflashes at 1 Hz.DMalfunction of output shaft speed sensor DMalfunction of direct planetary carrier DMalfunction of harness or connector DMalfunction of engine-A/T-ECU <6G7> DMalfunction of A/T-ECU<4M4> LRefer to the Transmission Workshop Manual.
