Error Code P00B4: What It Means & What To Do?
OBD Code P00B4 - Radiator Coolant Temperature Sensor Circuit High
Do you notice sudden decrease in the fuel economy? Are you experiencing some problems with the car engine not running properly and is the Check Engine Light on? All these are probable signs of OBD Code P00B4.
OBD-II Code Cooling fans may stay on all the time is defined as a
Radiator Coolant Temperature Sensor Circuit High
Learn More About OBD Code P00B4 Error
The CTS (Coolant Temperature Sensor) monitors the
temperature of the vehicle’s coolant and sends the signal to the PCM
(Powertrain Control Module). Based on
the temperature readings from the CTS (Coolant Temperature Sensor) the PCM
(Powertrain Control Module) adjusts the air/fuel mixture accordingly. When the PCM (Powertrain Control Module)
reads that the signals from the CTS (Coolant Temperature Sensor) are out of
vehicle specifications a trouble code will set.
What
causes the problem with the Radiator Coolant Temperature Sensor Circuit High?
- Faulty
radiator or other coolant temperature sensor (CTS) and Dirty/plugged sensor
pickup
- Leakage
O-ring/Gasket
- Broken
or damaged wiring and harness
- Blown Fuses
- PCM and Pin/connector problem (corrosion, melting, broken lock tab etc.)
