Description
INFOID:0000000005148550
The input speed sensor detects input shaft rpm (revolutions per minute). It is located on the input side of the
automatic transmission. Monitors revolution of sensor 1 and sensor 2 for non-standard conditions.
CONSULT-III Reference Value in Data Monitor Mode
INFOID:0000000005148551
On Board Diagnosis Logic
INFOID:0000000005148552
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0717 INPUT SPEED SENSOR A” with CONSULT-III is detected under the follow-
ing conditions.
- When TCM does not receive the proper voltage signal from the sensor.
- When TCM detects an irregularity only at position of 4GR for input speed sensor 2.
Possible Cause
INFOID:0000000005148553
• Harness or connectors
(The sensor circuit is open or shorted.)
• Input speed sensor 1, 2
DTC Confirmation Procedure
INFOID:0000000005148554
CAUTION:

3. Start engine and maintain the following conditions for at least 5 consecutive seconds.
VHCL/S SE-A/T: 40 km/h (25 MPH) or more
ENGINE SPEED: 1,500 rpm or more
ACCELE POSI: 0.5/8 or more
SLCT LVR POSI: “D” position
GEAR (Input speed sensor 1): 4th or 5th position
GEAR (Input speed sensor 2): All position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
4. If DTC is detected, go to
WITH GST
Follow the procedure “With CONSULT-III”.
