DTC P0717 TURBINE REVOLUTION SENSOR
DTC P0717 TURBINE REVOLUTION SENSOR PFP:31935
A
Description NCS001L8
The turbine revolution sensor detects input shaft rpm (revolutions per minute). It is located on the input side of
the automatic A/T. Monitors revolution of sensor 1 and sensor 2 for non-standard conditions. B
CONSULT-II Reference Value NCS001L9
Item name Condition Display value AT
TURBINE REV During driving (lock-up ON) Approximately matches the engine speed.
On Board Diagnosis Logic NCS001LA
D
● This is an OBD-II self-diagnostic item.
● Diagnostic trouble code “P0717 TURBINE REV S/CIRC” with CONSULT-II or 11th judgement flicker with-
out CONSULT-II is detected under the following conditions. E
– When TCM does not receive the proper voltage signal from the sensor.
– When TCM detects an irregularity only at position of 4th gear for turbine revolution sensor 2.
F
Possible Cause NCS001LB
● Harness or connectors
(Sensor circuit is open or shorted.) G
● Turbine revolution sensor 1 and/or 2
DTC Confirmation Procedure NCS001LC
H
CAUTION:
● Always drive vehicle at a safe speed.
● Be careful not to rev engine into the red zone on the tachometer.
I
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. J
WITH CONSULT-II
1. Turn ignition switch ON.
K
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “A/T” with CONSULT-II and check monitor “VHCL/S SE-A/T”,
“ENGINE SPEED”, “ACCELE POSI”, “SLCT LVR POSI ” and
“GEAR”. L
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5
consecutive seconds. M
VHCL/S SE-A/T: 40 km/h (25 MPH) or more
ENGINE SPEED: 1,500 rpm or more
ACCELE POSI: More than 0.5/8 BCIA0030E
SLCT LVR POSI: “D” position
GEAR (Turbine revolution sensor 1): “4” or “5” position
GEAR (Turbine revolution sensor 2): All positions
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
5. If DTC is detected, go to AT-118, "Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.

tom Chart" (Symptom No.47). I
OK or NG
OK >> GO TO 7.
NG >> Repair or replace damaged parts. J
A/T Does Not Shift: 4th Gear → 3rd Gear NCS001QH
SYMPTOM:
K
When shifted from M4 to M3 position in manual mode, does not downshift from 4th to 3rd gear.
DIAGNOSTIC PROCEDURE
