DTC P0711: Malfunction of Transmission Fluid Temperature Sensor
.
DIAGNOSTIC FUNCTION
TCM conducts fault detection by monitoring the ter-
minal voltage of the transmission fluid temperature
sensor.
.
DESCRIPTIONS OF MONITOR METHODS
• Field A : Transmission fluid temperature is less
than -20
°C (-4°F)
Field B : Transmission fluid temperature is -20
°C
(-4
°F) or more and less than 0°C (32°F)
Field C : Transmission fluid temperature is 0
°C
(32
°F) or more and less than 20°C (68°F)
When the transmission fluid temperature is kept
at one of fields A, B and C above for 10 minutes.
.
MONITOR EXECUTION
• Transmission range: D
• Vehicle speed : 10 km (6.2 mph) or more
• Throttle valve opening : 1/8 or more
• Engine speed : 450 r/min or more
.

DTC SET CONDITIONS
Check Conditions
• Transmission range switch position: D.
• Vehicle speed: 10 km/h (6.2 mph) or more.
• Throttle position sensor voltage: 1.37 volts or
more.
• Engine speed: 450 r/min or more.
Judgment Criteria
• Transmission fluid temperature is less than -20°C
(-4
°F) for 600 seconds or more
• Transmission fluid temperature is -20°C (-4°F) or
more and less than 0
°C (32°F)for 600 seconds or
more
• Transmission fluid temperature is 0°C (32°F) or
more and less than 20
°C (68°F) for 600 seconds
or more
.
OBD-II DRIVE CYCLE PATTERN
Transmission range: D (Drive the vehicle for 20 sec-
onds or more while the accelerator opening angle is
20% or more)
.
PROBABLE CAUSES
• Malfunction of transmission fluid temperature
sensor
• Malfunction of transmission fluid cooler piping
and oil pump
• Malfunction of TCM
DIAGNOSTIC PROCEDURE
STEP 1. Transmission fluid cooler piping and oil pump
check
Q: Is the check result normal?
YES : Go to Step 2.
NO : Repair the failure sections.
STEP 2. Transmission fluid temperature sensor check
Refer to
.
Q: Is the check result normal?
YES : Go to Step 3.
NO : Replace the valve body assembly.
STEP 3. Symptom recheck after erasing diagnosis code
Q: Is the check result normal?
YES : Intermittent malfunction
NO : Replace TCM.
