Error Code P0C70: What It Means & What To Do?

<<See All OBD Codes

Wondering on how to crack the error code P0C70? Well, we have it all in store for you! Here’s all you need to know about the error code P0C70. This generic OBD-II code wiring issue in simple terms is determined as a hybrid battery temperature sensor "C"/"D" correlation. To regulate the temperature of each battery cell, the hybrid battery pack employs a number of sensors. The code P0C70 is stored, if one of the battery temperature sensors receive an improbable temperature. There are also chances of a possible failure in the high voltage system if multiple sensors fail.

It should be noted that at 3 locations one can find the battery temperature sensors in the HV battery. Each battery temperature sensor has thermistors built in it. The resistance of the thermistors differs according to changes in the HV battery temperature. As the battery temperature decreases, there is an increase in the thermistor resistance. Whereas on the contrary, the resistance decreases when the temperature is increased. The HV battery temperature is detected by the battery smart unit using the battery temperature sensor. Further, this detected value is sent to the power management control ECU. In accordance with the results of the detection, the blower fan is monitored by the power management control ECU (when the HV battery temperature rises above the required level, the blower fan starts).

What causes this problem with the Hybrid Battery Temperature Sensor "C"/"D" Correlation?

• A possible fault in the hybrid battery thermistor
• A damaged battery smart unit
• The hybrid battery thermistor harness might be loose or short circuited
• A weak electrical connection in the hybrid battery thermistor circuit

1. Hybrid Battery Thermistor - A damaged hybrid battery thermistor can be extremely harmful as it triggers problems with engine too at times. It leads to the engine surging during functioning and also causes the voltage of the battery drain. So, in order fight the error code P0C70 it should be changed as soon as possible. Tune into Parts Avatar now!
2. Battery Smart Unit - See the check engine light illuminated? Well, it could be due to a malfunctioning battery smart unit. Not only this a defective battery smart unit causes a slow engine crank, and also a battery leakage at times. Now get your error code P0BC70 fixed right away with Parts Avatar. Tune in now for the best quality products in town!
3. HV Battery Assembly - A corroded or disconnected HV battery assembly can be troublesome. A battery assembly plays the role of connecting various parts of the system to the battery. An overall slow functioning of the system may be observed at times. Also, a sluggish crank may follow too. 
4. High voltage battery interface control module (HV BICM) - This performs the function of prolonging the life a battery, protect the cells or the battery from damage. If damaged, the whole system becomes prone to a slow functioning, shorter life span and also easy damage. Now you can get your error code P0C70 fixed with Parts Avatar. We are just a click away!

Here are some steps which you should follow in order to diagnose this fault code:

A standard OBD-II trouble code scanner should be used to diagnose this trouble code P0B70. The scanner will be used to check and view the freeze frame data and assess the code by a certified technician. The technician should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be restarted to see if the code pertains. If the code disappears it could likely be due to a faulty diagnose or may represent an intermittent issue.

Common Mistakes When Diagnosing the P0C70 Code

• Fearing a misdiagnosis? Well, we have listed here only for you a few common mistakes that should be avoided while performing the procedure:
• A fault in the high voltage battery assembly
• A defective high voltage battery interface control module
• Wiring issues in the system
