P0715 INPUT SPEED SENSOR A
P0715 INPUT SPEED SENSOR A
DescriptionINFOID:0000000005397832
The primary speed sensor detects the primary pul
ley revolution speed and sends a signal to the TCM.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005397833
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005397834
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0715” with CONSULT-III is detected when TCM does not receive the proper sig-
nal from the sensor.
Possible CauseINFOID:0000000005397835
• Harness or connectors (Sensor circuit is open or shorted.)
• Primary speed sensor
DTC Confirmation ProcedureINFOID:0000000005397836
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
2. Start engine and maintain the following conditions for at least 5 consecutive seconds.
VEHICLE SPEED: 10 km/h (6 MPH) or more
ACC PEDAL OPEN: More than 1.0/8
RANGE: “D” position
ENG SPEED: 450 rpm or more
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
3. If DTC is detected, go to CVT-74, "
Diagnosis Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.
Item name Condition Display value
ENG SPEED SIG Engine running Closely matches the tach ometer reading.
PRI SPEED SEN During driving (lock-up ON) Approximately matches the engine speed.
