What is OBD-II Code P23C6 – Engine Coolant Bypass Valve C Control Circuit Driver Current/Temperature Too High


Engine trouble codes provide essential information about components that are not working correctly in a vehicle. In this article, we will discuss OBD-II Code P23C6, which relates to the Engine Coolant Bypass Valve (ECBV) C Control Circuit Driver Current/Temperature Too High. We will explain what the code means, how it can be diagnosed, the recommended repair procedures, and some frequently asked questions related to this topic.

What is OBD-II Code P23C6 – Engine Coolant Bypass Valve C Control Circuit Driver Current/Temperature Too High?

P23C6 is an OBD-II code that indicates a problem with the Engine Coolant Bypass Valve (ECBV) C Control Circuit Driver Current/Temperature. The code signifies that the engine control module (ECM) has detected an abnormal current or temperature level in the ECBV control circuit. The severity of this issue can vary from minor to severe, depending on the severity of the problem.

Some of the most common symptoms associated with this code include:

– Illuminated check engine light
– Reduced engine performance
– Engine overheating
– Reduced fuel economy

In addition, the vehicle’s ECM may enter into a fail-safe mode as a protective measure to prevent further damage to the engine. In this mode, the engine output will be reduced, and the throttle response will be sluggish.

Diagnosing OBD-II Code P23C6 – Engine Coolant Bypass Valve C Control Circuit Driver Current/Temperature Too High:

Diagnosing the cause of OBD-II Code P23C6 typically involves performing a thorough visual inspection of the vehicle’s cooling system, including the ECBV and its associated wiring and connectors. In addition, a technician may use an OBD-II scanner to access the vehicle’s ECM and retrieve diagnostic trouble codes (DTCs) associated with the engine coolant system.

Once the diagnostic trouble codes have been retrieved, the technician will use the manufacturer-specified diagnostic procedures to pinpoint the root cause of the problem. Some of the most common causes of this problem include a faulty ECBV, damaged or corroded electrical connectors, a short circuit in the wiring harness, or a failed ECM. In some cases, a malfunctioning thermostat or cooling system fan may also be the cause of the problem.

Repairing OBD-II Code P23C6 – Engine Coolant Bypass Valve C Control Circuit Driver Current/Temperature Too High:

The repair procedure for OBD-II Code P23C6 will depend on the underlying cause of the problem. If the problem is caused by a faulty ECBV, the valve will need to be replaced. Additionally, if electrical connections, wiring harnesses, or other electrical components are found to be damaged or corroded, they will need to be repaired or replaced as well.

If the problem is caused by a damaged ECM, the module may need to be replaced or reprogrammed. In some cases, a software update may be available that can resolve the issue.
