Details On DTCs

Description

ECT sensor No.2 circuit range/performance problem

Detection condition
Determination conditions
• During the 7 min after the engine is started, the engine coolant temperature does not increase above 3 °C {5 °F}.
Preconditions
• Before starting the engine, leave the vehicle with the engine turned off for 6 hours or more.
• The following DTCs are not detected:
― ECT sensor No.2: P2184:00 and P2185:00
Drive cycle
• 2
Self test type
• CMDTC self test
Sensor used
• ECT sensor No.2
Fail-safe function
• Not applicable
Vehicle status when DTCs are output
• Not applicable
Possible cause
• ECT sensor No.2 connector or terminals malfunction
• PCM connector or terminals malfunction
• ECT sensor No.2 incorrect installation
• ECT sensor No.2 malfunction
• Poor assembly of engine coolant hose (engine coolant passage malfunction)
• Poor engine coolant, leakage, or freezing
• Use of unspecified engine coolant
• Coolant control valve malfunction
• PCM malfunction



System Wiring Diagram

• Not applicable



Function Explanation (DTC Detection Outline)

• If the engine coolant temperature detected by the ECT sensor No.2 is not rising 3 °C {5 °F} or more during a 7 min period after the engine is started, the PCM determines an ECT sensor No.2 malfunction and stores a DTC.

Repeatability Verification Procedure

1. Start the engine and leave it idling for 10 s.
2. Switch the ignition off.
3. Leave the vehicle for 6 hours or more.
4. Start the engine and leave it idling for 8 min.

1
PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY
• Verify related Service Bulletins, on-line repair information, or Service Information availability.
• Is any related Information available?
Yes
Perform repair or diagnosis according to the available information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
• Record the freeze frame data/snapshot data.

Note
• Recording can be facilitated using the screen capture function of the PC.
Go to the next step.
3
PURPOSE: VERIFY CONNECTOR CONNECTIONS
• Start the engine.
• Access the ECT2_VOLT PID using the M-MDS. (See PID/DATA MONITOR INSPECTION.)
• Does the PID value fluctuate when the following connectors are shaken?
― ECT sensor No.2
― PCM
Yes
Repair or replace the applicable connector parts.
Go to Troubleshooting Diagnostic Procedure to perform the repair completion verification.
No
Go to the next step.
4
PURPOSE: VERIFY ECT SENSOR No.2 INPUT SIGNAL
• Access the ECT2_VOLT PID using the M-MDS. (See PID/DATA MONITOR INSPECTION.)
• Is the PID value within specification?
Yes
Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 3.
No
Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.



Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure
• Step 1—2
― Perform an ECT sensor No.2-related inspection.
• Step 3—5
― Perform an engine coolant-related inspection.
• Step 6
― Perform a unit inspection of the coolant control valve.
• Repair completion verification
― Verify that the primary malfunction is resolved and there are no other malfunctions.

Step

Inspection

Action

1
PURPOSE: VERIFY IF ECT SENSOR No.2 IS INSTALLED CORRECTLY
• Is the installation condition normal?
Yes
Go to the next step.
No
Correctly install the ECT sensor No.2 and perform the repair completion verification.
2
PURPOSE: INSPECT ECT SENSOR No.2 FOR MALFUNCTION
• Is the part normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
3
PURPOSE: VERIFY IF MALFUNCTION CAUSED BY POOR ENGINE COOLANT PASSAGE ASSEMBLY
• Is there any malfunction?
Yes
Reconnect the engine coolant passage correctly.
Replace the engine coolant and perform the repair completion verification.
No
Go to the next step.
4
PURPOSE: VERIFY IF MALFUNCTION RELATED TO ENGINE COOLANT AFFECTS DIAGNOSTIC RESULTS
• Inspect the following:
― Is the system filled with the specified engine coolant?
― Is there the possibility of freezing (low engine coolant concentration)?
― Has foreign matter penetrated the engine coolant?
• Are all items normal?
Yes
Go to the next step.
No
Replace the engine coolant and perform the repair completion verification. (Advise the customer to use specified engine coolant used.)
5
PURPOSE: VERIFY IF MALFUNCTION RELATED TO ENGINE COOLANT LEAKAGE FROM ENGINE COOLANT PASSAGE AFFECTS DIAGNOSTIC RESULTS
• Is there engine coolant leaking from the engine coolant passage?
Yes
Repair or replace the malfunctioning location and refill the system with engine coolant.
Go to repair completion verification.
No
Go to the next step.
6
PURPOSE: INSPECT COOLANT CONTROL VALVE FOR MALFUNCTION
• Is the part normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
Repair completion verification 1
PURPOSE: VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
― Implement the repeatability verification procedure. (See Repeatability Verification Procedure.)
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, perform the diagnosis from Step 1.
No
Go to the next step.
Repair completion verification 2
PURPOSE: VERIFY IF OTHER DTCs DISPLAYED
• Perform the DTC inspection. (See DTC INSPECTION.)
• Are any other DTCs displayed?
