Input Shaft Speed Sensor and Output Shaft Speed Sensor System Circuit
DTC SET CONDITIONS:
If the PCM receives a signal (multiplied by the 1stgear ratio) from the output shaft speed sensor that is not the same as the signal received from the input shaft speed sensor (while driving with the transmission in 1st gear), DTC 41 is set. If DTC 41 is set four times, the transmission is locked into 3rd gear as a fail-safe measure, and the "N" range light flashes once per second.
The most likely
causes for this code to be set are:
- Malfunction of the input shaft speed sensor
- Malfunction of the output shaft speed sensor
- Malfunction of the PCM
- Malfunction of the reverse clutch retainer
- Malfunction of the direct planetary carrier
- Malfunction of the low-reverse brake system (DTC 41 or DTC 46)
- Malfunction of the underdrive clutch system (DTC 41, DTC 42, DTC 43 or DTC 44)
- Malfunction of the second brake system (DTC 42 or DTC 45)
- Malfunction of the overdrive clutch system (DTC 43, DTC 44 or DTC 45)
- Malfunction of the reverse clutch system (DTC 46)
- Malfunction of the direct clutch system (DTC 44 or DTC 45)
- Malfunction of the reduction brake system (DTC 41, DTC 42, DTC 43 or DTC 46)
