DTC P2183: ECT Sensor 2 Circuit Range/Performance Problem

NOTE: 

• Before you troubleshoot, review the general troubleshooting information - Refer to: How to Troubleshoot the Fuel and Emissions SystemsHow to Troubleshoot the CVT System(CVT System) .
• If DTC P0111 is stored at the same time as DTC P2183, troubleshoot DTC P0111 first, then recheck for DTC P2183.

DTC (PGM-FI)

• 1. Connector visual check:

  - 1. Check for poor connections or loose terminals and terminals at these sensors:

  • ECT sensor 1
  • ECT sensor 2

  Are the connections and terminals OK?

  YES 

  Go to step 2.

  NO 

  Repair the connections or terminals.

• 2. PGM-FI system check:

  - 1. Turn the vehicle to the ON mode.

  - 2. Check for Pending or Confirmed DTCs with the HDS.

  DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
  P1116 ECT Sensor 1 Circuit Range/Performance Problem
  P2183 ECT Sensor 2 Circuit Range/Performance Problem

  Are DTC P1116 and P2183 indicated at the same time?

  YES 

  Go to step 5.

  NO 

  Go to step 3.

• 3. ECT sensor 2 performance check:

  - 1. Start the engine, and let it idle for 10 minutes.

  - 2. Check the parameter(s) below with the HDS.

  Signal	Threshold		Current conditions
  	Values	Unit	Values	Unit
  ECT SENSOR 2	Less than 120	°F

  Do the current condition(s) match the threshold?

  YES 

  Replace ECT sensor 2 - Refer to: ECT Sensor 1 Removal and InstallationECT Sensor 2 Removal and Installation .

  NO 

  Go to step 4.

• 4. Problem verification:

  - 1. Turn the vehicle to the OFF (LOCK) mode.

  - 2. Allow ECT sensor 2 to cool to the ambient temperature.

  - 3. Note the ambient temperature.

  - 4. Turn the vehicle to the ON mode.

  - 5. Quickly note the value of ECT SENSOR 2 in the DATA LIST with the HDS.

  Signal	Current conditions
  	Values	Unit
  ECT SENSOR 2

  Does the value of ECT SENSOR 2 differ 5.4°F (3°C) or more from the ambient temperature?

  YES 

  The failure is duplicated. Replace ECT sensor 2 - Refer to: ECT Sensor 1 Removal and InstallationECT Sensor 2 Removal and Installation .

  NO 

  Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

• 5. ECT sensor 1 performance check:

  - 1. Start the engine, and let it idle for 10 minutes.

  - 2. Check the parameter(s) below with the HDS.

  Signal	Threshold		Current conditions
  	Values	Unit	Values	Unit
  ECT SENSOR 1	Less than 120	°F

  Do the current condition(s) match the threshold?

  YES 

  Replace ECT sensor 1 - Refer to: ECT Sensor 1 Removal and InstallationECT Sensor 2 Removal and Installation .

  NO 

  ECT sensor 1 is OK at this time. Go to step 6.

• 6. ECT sensor 2 performance check:

  - 1. Let the engine idle for 10 minutes.

  - 2. Check the parameter(s) below with the HDS.

  Signal	Threshold		Current conditions
  	Values	Unit	Values	Unit
  ECT SENSOR 2	Less than 120	°F

  Do the current condition(s) match the threshold?

  YES 

  Replace ECT sensor 2 - Refer to: ECT Sensor 1 Removal and InstallationECT Sensor 2 Removal and Installation .

  NO 

  Go to step 7.

• 7. Problem verification:

  - 1. Turn the vehicle to the OFF (LOCK) mode.

  - 2. Allow the sensors to cool to the ambient temperature.

  - 3. Note the ambient temperature.

  - 4. Turn the vehicle to the ON mode.

  - 5. Quickly note the value of ECT SENSOR 1 and ECT SENSOR 2 in the DATA LIST with the HDS.

  Signal	Current conditions
  	Values	Unit
  ECT SENSOR 1
  ECT SENSOR 2

  - 6. Compare the value of ECT SENSOR 1 to the ambient temperature, and the value of ECT SENSOR 2 to the ambient temperature individually.

  Does either sensor differ more than 5.4°F (3°C) from the ambient temperature?

  YES 

  Replace the sensor that differed more than 5.4°F (3°C) from the ambient temperature.

  NO 

  Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
