DTC P1700 Speed sensor No. 2 Circuit Malfunction
(Front Speed Sensor)
CIRCUIT DESCRIPTION
The front speed sensor detects the vehicle speed based on revolution of the ring gear and sends signals
to the ECM. An AC voltage is generated in the front speed sensor coil as the ring rear mounted on the ring
gear rotates, and this voltage is sent to the ECM.
The center differential clutch is controlled by the ECM based on the signals from the front speed sensor and
rear speed sensor signals.
DTC No.DTC Detecting ConditionTrouble Area
P1700
All condition below are detects 5,400 times or more continu-
ously
(a) No signal from front speed sensor is input to ECM while 4
pulses of rear speed sensor is sent
(b) Vehicle speed: 18 km/h (11 mph) or more for at 4 sec.
(c) Park / neutral position switch:
OFF (Other than P or N position)

INSPECTION PROCEDURE
1 Check vehicle speed value or resistance between terminals FR+ and FR− of ECM.
When using OBD II scan tool or TOYOTA hand−held tester:
PREPARATION:
(a) Remove the DLC3 cover.
(b) Connect an OBDII scan tool or TOYOTA hand−held tester
to the DLC3.
(c) Turn the ignition switch ON and OBD II scan tool or TOY-
OTA hand−held tester main switch ON.
CHECK:
Drive the vehicle and read vehicle speed value.
OK:
Vehicle speed matches tester speed value.
When not using OBD II scan tool or TOYOTA hand−held tes-
ter:
CHECK:
Check the resistance between terminals FR+ and FR− of the
ECM.
OK:
Resistance: 560 − 680 Ω
OK Check and replace ECM.

CHECK:
Measure the resistance between terminals 1 and 2 of the speed
sensor.
OK:
Resistance: 560 − 680 Ω
Reference:
Check the front transaxle revolution sensor’s function
CHECK:

sor when a magnet is put close to the front end of the front
speed sensor then taken away quickly.
OK:
Voltage is generated intermittently.
HINT:
The generated voltage is extremely low.
NG Replace front speed sensor.
OK
Check and repair harness and connector be-
tween ECM and front speed sensor.

Check solenoid resistance:
PREPARATION:
(a) Jack up the vehicle.
(b) Remove the oil pan.
(c) Disconnect the connector.
CHECK:
