DTC P00B1-62: Radiator Coolant Temperature Sensor Signal Compare Failure [11/2023 - ]: Procedure

1. Read the DTCs and record the Freeze Frame Data.

   Powertrain > Engine > Trouble Codes 

   Result

   Result	Proceed to
   DTC P00B1-62 is output	A
   DTC P00B1-62 and other DTCs are output	B

   HINT: 

   If any DTCs other than P00B1-62 are output, troubleshoot those DTCs first.

Result: 

B 

GO TO DTC CHART  . Refer to DIAGNOSTIC TROUBLE CODE CHART [11/2023 - 11/2024] , or refer to DIAGNOSTIC TROUBLE CODE CHART [11/2024 - ]

Result: 

A 

See step  2

1. Using the GTS, read the values displayed in the Freeze Frame Data recorded in step 1.

   Powertrain > Engine > DTC (P00B1-62) > Freeze Frame Data 

   Tester Display
   Coolant Temperature
   Radiator Coolant Temperature

2. Read the value displayed on the GTS.

   Standard

   Difference between the Coolant Temperature and the Radiator Coolant Temperature is within 15°C (27°F).

   HINT: 

   When the engine is cold, the value of the intake air temperature, ECM internal temperature and ambient temperature should be approximately the same.

   Result

   Proceed to
   OK
   NG

Result: 

NG 

REPLACE NO. 2 ENGINE COOLANT TEMPERATURE SENSOR 

Refer to PROCEDURE - Step 2

Result: 

OK 

See step  3

1. Using the GTS, read the values displayed in the Freeze Frame Data recorded in step 1.

   Powertrain > Engine > DTC (P00B1-62) > Freeze Frame Data 

   Tester Display
   Coolant Temperature
   Intake Air Temperature

2. Read the value displayed on the GTS.

   Standard

   Difference between the Coolant Temperature and the Intake Air Temperature is within 15°C (27°F).

   HINT: 

   • When the engine is cold, the value of the intake air temperature, ECM internal temperature and ambient temperature should be approximately the same.
   • Perform "Inspection After Repair" after replacing the engine coolant temperature sensor.
