INPUT SPEED SENSOR A
INPUT SPEED SENSOR A
DescriptionINFOID:0000000005397371
The input speed sensor detects forward clutch drum rpm (revolutions per minute). It is located on the input
side of the automatic transaxle. The output speed sensor is located on the output side of the automatic tran-
saxle. With the two sensors, input and output rpms are accurately detected. As a result, optimal shift timing
during deceleration and shift quality can be improved.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005397372
Remarks: Specification data are reference values.
On Board Diagn osis LogicINFOID:0000000005397373
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “INPUT SPEED SENSOR A” wi th CONSULT-III or 10th judgement flicker without

Possible CauseINFOID:0000000005397374
• Harness or connector
(The sensor circuit is open or shorted.)
• Input speed sensor
DTC Confirmation ProcedureINFOID:0000000005397375
CAUTION:
• Always drive vehicle at a safe speed.
• Be careful not to rev engine into the red zone on the tachometer.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following proc edure to confirm the malfunction is eliminated.
