< COMPONENT DIAGNOSIS >

P0717 INPUT SPEED SENSOR A

P0717 INPUT SPEED SENSOR A

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:

Always drive vehicle at a safe speed.

NOTE:

If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”

and wait at least 10 seconds before performing the next test.

After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-III

1. Turn ignition switch “ON”. (Do not start engine.)

2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

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 

TM-48, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “With CONSULT-III”.

Diagnosis Procedure

INFOID:0000000005148555

1.

CHECK INPUT SIGNAL

With CONSULT-III

1. Start engine.

2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

3. Vehicle start and read out the value of “INPUT SPEED”.
