Volvo Engine Code MID 130 PID 161 FMI 1
MID 130 PID 161 Input Shaft, Rotation Speed Type of fault: FMI 1 FMI Description: • Data valid but below operational range Fault Condition: • The sensor signal is within normal range and, • The counter shaft speed differs from both the main shaft speed (SESM) and the vehicle speed received from the VECU when the counter shaft is rotating The following conditions must be fulfilled for a time of 2.0 s in order to activate: • A gear (not neutral) is engaged in the transmission • The value of the input shaft speed calculated from the main shaft speed sensor (SESM) is more than 300 rpm • The value of the input shaft speed calculated from the counter shaft speed sensor (SESC) is more than 300 rpm • The values of the input shaft speed calculated from the counter shaft speed sensor (SESC) and the main shaft speed sensor (SESM) differ more than 50 rpm • The values of the input shaft speed calculated from the counter shaft speed sensor (SESC) and the vehicle speed received from the VECU differ more than 30 rpm • The values of the input shaft speed calculated from the main shaft speed sensor (SESM) and the vehicle speed received from the VECU differ less than 30 rpm Possible Symptoms: • Yellow lamp is sent • Slow gear changes • Transmission brake up-shifts cannot be used • Engagement point not functioning properly • Starting gear can only be engaged when the vehicle is stationary or when the vehicle speed is high enough to synchronize the transmission with the engine Possible Cause: N/A
