DTC P011A-62: Engine Coolant Temperature Sensor 1/2 Signal Compare Failure; DTC P111A-62: Engine Coolant Temperature Sensor 1/3 Signal Compare Failure [12/2017 - ]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Trouble Codes.
5. Read the DTCs.

   Powertrain > Engine > Trouble Codes 

   Result

   Result	Proceed to
   DTC P011A-62 is output	A
   DTC P111A-62 is output	B
   DTC P011A-62 and P111A-62 are output	C

6. Record the freeze frame data.

   HINT: 

   • When the engine is cold, the value of the engine coolant temperature sensor (for inlet side), engine coolant temperature sensor (for cylinder head side) and engine coolant temperature sensor (for outlet side) should be approximately the same.
   • If only one of the sensors has deviating output values, this sensor may be malfunctioning.

See step  6

1. Connect the Techstream to the DLC3.
2. Start the engine and fully warm up the engine with the air conditioning off until the electric cooling fan starts to operate.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine / Data List / Coolant Temperature Sensor1, Coolant Temperature Sensor2 and Coolant Temperature Sensor3.

   Powertrain > Engine > Data List 

   Tester Display
   Coolant Temperature Sensor1
   Coolant Temperature Sensor2
   Coolant Temperature Sensor3

5. Read the Data List, when the engine is fully warmed up.

   Standard

   Techstream Display	Condition	Specified Condition
   Difference between Coolant Temperature Sensor1 and Coolant Temperature Sensor2	After fully warming up	Within 20°C (36°F)
   Difference between Coolant Temperature Sensor1 and Coolant Temperature Sensor3

   HINT: 

   The engine can be judged as fully warmed up after warming up the engine with the air conditioning off until the electric cooling fan starts to operate.
