P0C7D OBD Error Code: Problem & Solutions

<<See All OBD Codes

Do you find the battery smart unit to be damaged? Is the P0C7D error stored in your vehicle? Keep reading further to know as to how to diagnose this error code. The hybrid battery temperature sensor ‘G’ range/performance is usually referred to the wiring issue in the vehicle. With the help of multiple sensors, the temperature of each battery cell is monitored by the hybrid battery pack. If an unlikely signal is reported by at least one of the battery temperature sensors, a P0C7D error code will be set. The disabling of a high voltage system will occur if multiple sensors fail.

There are 3 locations available for the battery temperature sensor in the HV battery. In each battery temperature sensor, thermistor’s resistance is built and it will vary in correspondence to the HV battery temperature. If the battery temperature is low, the resistance of thermistor will be high. On the contrary, if the temperature is high, resistance will be low. The battery smart unit finds the HV battery temperature with the help of battery temperature sensors. The power management control ECU then receives the identified value. Based on the results of this identification, the blower fan is controlled by the power management control ECU.

What causes this problem with the Hybrid Battery Temperature Sensor "G" Range /Performance?

• Defective hybrid battery thermistor.
• The hybrid battery thermistor harness might have an opening or short circuit.
• The hybrid battery thermistor circuit might have a weak electrical connection.
• The battery smart unit might be damaged.

1. Hybrid Battery Temperature Sensor - Hybrid battery temperature sensor can fail if the voltage of the battery is low which further sends an incorrect signal to the computer. Replace it quickly to avoid the P0C7D error code getting stored.
2. Engine Wiring Connectors - The engine wiring connectors can give rise to issues in your vehicle if they are corroded. The corroded or damaged engine wiring connectors need immediate replacement so that the P0C7D error is avoided
3. Battery Temperature Sensors - The battery temperature sensors can also fail if there is a huge amount of corrosion on the battery as well as the sensor itself which will likely result in malfunctioning of the vehicle. Replace it quickly so that the engine functions normally.
4. Electronic Pressure Regulator - A defective electronic pressure regulator will indicate you with misfiring conditions and poor engine performance. Get it repaired/ replaced to avoid the P0C7D error code.
5. Battery Assembly - One of the common symptoms for the failure of the battery assembly is the corrosion of batteries. The corroded batteries have to be replaced soon to avoid further troubles.
6. Automatic Transmission Fluid - The automatic transmission fluid must be quickly changed if the dipstick shows dark or burnt smelling fluid. Get the right automatic transmission fluid for your vehicle from Parts Avatar.
7. Automatic Transmission Shift Solenoid - Flashing of the check engine light is an indication that the automatic transmission shift solenoid is faulty. Repair it immediately to avoid further troubles.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0C7D here:

Common Symptoms

• You might notice the flashing of the engine light and the warning light of the service engine.

Here are some ways with the help of which you will be able to correct the OBD Code P0C7D

• Defective shift solenoid has to be changed.
• Broken engine wiring connectors need to be fixed.
• Fixing the damaged hybrid battery thermistor.
• The defective harness or the circuit of the hybrid battery thermistor needs fixation.

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out!

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• You will find an erratic condition if the code fails to return quickly.
• As there are many circuits involved, these diagnostic codes are best to be left to the experienced professionals.
• Remove the transmission pan and check for rubbles or other clutch materials if the fluid smells or appears to be burnt.
• Blocked hydraulic passage, a faulty pump. Malfunctioning shift solenoids or broken electronic pressure regulator are some of the reasons for low pump pressure.
• You will hear banging or crouching noise if the engine mountings are broken.
• There are usually 2 types of mounting - one is placed centrally, very near to the bottom of the block and the other one is placed a little high, on the inner side of the wings or chassis members.
• In P0C7D error code, the vehicle which is electronically controlled with the help of automatic transmission, the 3-4 shift solenoids that are present inside is accountable for actuating the hydraulic circuits to start the clutches or bands so that it can change the gear inside the automatic transmission.

Common Mistakes When Diagnosing The P0C7D Code

• The high voltage battery assembly might be defective.
• Problematic wires.
• Defective high voltage battery interface control module.
