Code No. 22 Input shaft speed sensor systemProbable cause
If no output pulse from the input shaft speed sensor is detected for 1 second or
more while the vehicle is driving at 30 km/h or more in 4th, it isjudged that
there is a short-circuit oropencircuit in the input shaft speed sensor, and code
No. 22 is output.
If code No. 22 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 input shaft speed sensor
