Guide To P0C72 OBD Error Code Solutions

<<See All OBD Codes

Check Engine” as alarming as it sounds. Not anymore! Parts Avatar is here to simplify all your problems. The OBD-II code P0C72 is determined as hybrid battery temperature sensor "E"/"F" correlation. The hybrid battery pack employs numerous sensors to control the temperature of each battery cell. Whenever an impractical signal is reported by any of the battery temperature sensors, the code P0C72 is stored. A failure in the sensors leads to a faulty high voltage system.

It is notable that the battery temperature sensors are present at 3 different locations of the HV battery. Also, the resistance of the thermistor (crafted in the battery temperature sensor) changes according to the variations in the HV battery temperature. As the battery temperature falls the thermistor resistance rises. While on the other hand, an increase in the temperature leads to a decrease in the resistance. Further the battery smart unit utilizes the battery temperature sensors to identify the HV battery temperature. This value is transmitted to the power management control ECU. On the basis of the detection, the power management control ECU regulates the blower fan. The blower fan activates whenever the HV battery temperature increases above the prespecified level.

What causes this problem with the Hybrid Battery Temperature Sensor "E"/"F" Correlation?

• A failure in the hybrid battery thermistor
• A damaged battery smart unit
• Open or short-circuited hybrid battery thermistor harness
• A bad electrical connection in the hybrid battery thermistor circuit

1. Hybrid Battery Thermistor - Having problems with the hybrid battery thermistor? Don’t you worry, Parts Avatar has it all. A faulty hybrid battery thermistor could end up being the root cause behind the error code P0C72. Its harmful effects also lead to complications while starting the vehicle and a disbalance in the system voltage is triggered too.
2. Battery Smart Unit - Hate the halts? Well, it could be caused due to a lot of reasons. Battery leak, very slow engine cranks and corrosion in the electrical components located around the battery smart unit is likely to be noticed as soon as the battery smart unit is diagnosed to be damaged. We have got you the perfect solution! Tune into Parts Avatar for top notch battery smart units delivered right at your doorstep.
3. HV Battery Assembly - Anxious? Can’t figure out the root to all these problems? The battery assemblies present play the role of connecting the battery cables to the battery. While they are defective the three are increased chances of a possible failure in the entire system. Difficulty in starting the vehicle and also rapid clicking while the vehicle starts is likely to be observed as initial signs of a failure in the battery assembly. Mend or restore yours now from Parts Avatar.
4. High Voltage Battery Interface Control Module (HV BICM) - This essential unit if malfunctioning should be changed right away in order to avoid a number of problems that come along a damaged high voltage battery interface control module. A sluggish engine crank and dimmed headlights are also caused too. Repair or replace from Parts Avatar just in time.

It is essential to diagnose this fault code. Here are some steps which a technician should follow for diagnosing the problem that triggered a P0B72 code to be stored:

To diagnose this error code P0C72, first and foremost for the technicians it is essential that they should make use of a device called an OBD-II scanner. This scanner should be connected to the onboard computer inside of the vehicle. It will then retrieve data from the vehicle to determine what issues might be present in the vehicle. The technician will likely first clear the code and then retest the vehicle. If there is an issue, the code will reappear. From that moment, the technician can start to narrow down the actual cause and determine what needs to be done to repair the vehicle.

Common Mistakes When Diagnosing the P0C72 Code

Only for you we have written here a few basic mistakes that should be avoided while diagnosing the error code P0C72:

• A fault in the high voltage battery assembly
• A failure in the high voltage battery interface control module
• Wiring issues in the system
