P00B1 OBD-II: Radiator Coolant Temperature Sensor Circuit
P00B1 Severity
Should you fix P00B1 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.

The Radiator Coolant Temperature Sensor tells the engine control module (PCM) the temperature of the coolant in the radiator. When the PCM detects an incorrect signal from the Radiator Coolant Temperature Sensor, the PCM will set code P00B1.
