P0711

K41B CVT: CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM: P0711: Transmission Fluid Temperature Sensor "A" Performance
P0711 - Transmission Fluid Temperature Sensor "A" Performance

DESCRIPTION

The CVT fluid temperature sensor converts the fluid temperature into a resistance value which is input to the ECM.

The sensor resistance changes with the transmission fluid temperature. As the temperature rises, the sensor resistance decreases. The ECM applies a voltage to the temperature sensor through ECM terminal THO1, and the ECM calculates the fluid temperature based on the voltage signal.

HINT
The CVT fluid temperature is likely to increase under conditions such as towing, climbing hills and in traffic.





MONITOR DESCRIPTION

The CVT fluid temperature sensor converts the CVT fluid temperature to an electrical resistance value. Based on the resistance, the ECM determines the CVT fluid temperature and detects opens or shorts in the CVT fluid temperature circuit.

After driving the vehicle for a certain period, the CVT fluid temperature should increase. When the CVT fluid temperature is below 20°C (68°F), the ECM interprets this as a fault, turns on the MIL.

When the CVT fluid temperature is 100°C (212°F) or more and engine coolant temperature reaches 35°C (95°F) after engine cold start, the ECM also determines this as a fault, turns on the MIL, and stores the DTC.

INSPECTION PROCEDURE

NOTICE:
Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

PROCEDURE

1. CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P0711)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine and ECT / DTC / Current or Pending.

(e) Read the DTCs using the Techstream.

Result





HINT
If any other DTCs besides P0711 are output, perform troubleshooting for those DTCs first.

B -- GO TO DTC CHART K41B Continuously Variable Transmission/Transaxle, CVT
A -- Continue to next step.

2. CHECK TRANSMISSION FLUID LEVEL

(a) Check the CVT fluid level Procedures.

OK:

CVT fluid level is correct.

NG -- ADD FLUID
OK -- Continue to next step.

3. REPLACE CONTINUOUSLY VARIABLE TRANSAXLE ASSEMBLY

(a) Replace the continuously variable transaxle assembly Removal.

NEXT -- Continue to next step.

4. PERFORM INITIALIZATION P0705
