P0717 INPUT SPEED SENSOR A
DescriptionINFOID:0000000003771847
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 ModeINFOID:0000000003771848
On Board Diagnosis LogicINFOID:0000000003771849
 This is an OBD-II self-diagnostic item.
 Diagnostic trouble code “P0717” with CONSULT-III is detected under the following conditions.
- When TCM does not receive the proper voltage signal from the sensor.
- When TCM detects an irregularity only at pos ition of 4GR for input speed sensor 2.
Possible CauseINFOID:0000000003771850
 Harness or connectors
(The sensor circuit is open or shorted.)
 Input speed sensor 1, 2
DTC Confirmation ProcedureINFOID:0000000003771851
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 senso r 2): All position
Driving location: Driving the vehic le uphill (increased engine load) will help maintain the driving
conditions required for this test.
4. If DTC is detected, go to TM-47, "Diagnosis Procedure"
.
WITH GST
Follow the procedure “With CONSULT-III”.
Diagnosis ProcedureINFOID:0000000003771852
1.CHECK INPUT SIGNAL
With CONSULT-III
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONITO R” mode for “TRANSMISSION” with CONSULT-III.
3. Vehicle start and read out t he value of “INPUT SPEED”.
Item name Condition Display value (rpm)
INPUT SPEED During driving (lock-up ON) Approximately matches the engine speed.

< PRECAUTION >
PRECAUTIONS
 All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection orreassembly.
 Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
 It is very important to perform functional tests whenever they are indicated.
 The valve body contains precision parts and requires extreme care when parts are removed and serviced. Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent springs
and small parts from becoming scattered or lost.
 Properly installed valves, sleeves, plugs, etc. will s lide along bores in valve body under their own weight.
 Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings and
seals, or hold bearings and washers in place during assembly. Do not use grease.
 Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
 Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to TM-
183, "A/T Fluid Cooler Cleaning".
 After overhaul, refill the transmission with new ATF.
 When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque con- verter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer to
TM-181, "Changing the A/T Fluid (ATF)"
.
Service Notice or PrecautionINFOID:0000000003772016
ATF COOLER SERVICE
 If A/T fluid contains fictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T fluid cooler mounted in the radiat or or replace the radiator. Flush cooler lines with
cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to TM-183,
"A/T Fluid Cooler Cleaning". For radiator replacement, refer to CO-15, "Removal and Installation".
CHECKING AND CHANGING A/T FLUID
 Increase ATF oil temperature to 80 °C (176 °F) first, then check and adjust oil level at 65 °C (149 °F).
NOTE:
The A/T has both water cooling and air cooling systems . The air cooling system has a bypass valve. When
ATF oil temperature is at or below 50 °C (122 °F), it does not flow through the air cooled system. If A/T oil
level is adjusted without flow throughout the entir e system, the level will be 10mm lower than required.
Therefore, all piping should be filled with oil when adjusting level.
OBD-II SELF-DIAGNOSIS
 A/T self-diagnosis is performed by the TCM in combination with the ECM. Refer to the table on TM-32,
"CONSULT-III Function (TRANSMISSION)" for the indicator used to display each self-diagnostic result.
 The self-diagnostic results indicated by the MIL ar e automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure on TM-30, "OBD-II Diagnostic Trouble Code (DTC)"
to complete the
repair and avoid unnecessary blinking of the MIL.
For details of OBD-II, refer to TM-30
.
 Certain systems and components, especially those related to OBD, may use the new style slide-
locking type harness connector. For descrip tion and how to disconnect, refer to PG-68
.
