AT-109

2007 Pathfinder

DTC P0717 TURBINE REVOLUTION SENSOR

PFP:31935

Description

ECS00EHQ

The turbine revolution 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-II Reference Value

ECS00EHR

On Board Diagnosis Logic

ECS00EHS

●

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.

–

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.

Possible Cause

ECS00EHT

●

Harness or connectors
(The sensor circuit is open or shorted.)

●

Turbine revolution sensor 1, 2

DTC Confirmation Procedure

ECS00EHU

CAUTION:

●

Always drive vehicle at a safe speed.

●

Be careful not to rev engine into the red zone on the tachometer.

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-II

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

Select “DATA MONITOR” mode for “A/T” with CONSULT-II.

Start engine and maintain the following conditions for at least 5
consecutive seconds.
VHCL SPEED SE: 40 km/h (25 MPH) or more
ENGINE SPEED: 1,500 rpm or more
ACCELE POS: 0.5/8 or more
Selector lever: “D” position
Gear position (Turbine revolution sensor 1): 4th or 5th posi-
tion
Gear position (Turbine revolution sensor 2): All position
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions required for this test.

If DTC is detected, go to

AT-110, "Diagnostic Procedure"

WITH GST

Follow the procedure “WITH CONSULT-II”.
