DTC P1716 TURBINE REVOLUTION SENSOR

DTC P1716 TURBINE REVOLUTION SENSOR

PFP:31935

Description

ACS0048E

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

ACS004PD

On Board Diagnosis Logic

ACS0048F

●

This is an OBD-II self-diagnostic item.

●

Diagnostic trouble code “TURBINE REV S/CIRC” with CONSULT-II or P1716 without 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

ACS0048G

●

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

●

Turbine revolution sensor 1, 2

DTC Confirmation Procedure

ACS0048H

CAUTION:

Always drive vehicle at a safe speed.

NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-II

1.

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

2.

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

3.

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

4.

If DTC is detected, go to 

AT-162, "Diagnostic Procedure"

 .

 WITH GST

Follow the procedure “With CONSULT-II”.
