P00B5

DTC P00B5, sometimes indicated as P00B500 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing radiator coolant temperature sensor circuit intermittent/erratic.

This code is caused by a problem with the radiator coolant temperature sensor or its circuit. There are several possible causes for this, including a bad sensor, a wiring problem, or a fault in the PCM.
If the sensor is bad, it will need to be replaced. If the wiring is at fault, it will need to be fixed. If the PCM is at fault, it will need to be replaced.
