P050C Severity
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
In order for the Powertrain Control Module (PCM) to maintain efficient fuel economy and minimize the emissions output from a vehicle, the engine cooling system must reach a critical operating temperature. This temperature, typically between 160-170 degrees, must be reached within 15 minutes after engine startup. If the weather is extremely cold, the coolant temperature must rise at least 70+ degrees starting temperature. If the coolant temperature does not reach operating temperature, or the temperature wanders excessively from this temperature, the PCM can't accurately and efficiently control fuel economy and emissions. The PCM will set code P050C.
