P050C - OBD Trouble Code

<<See All OBD Codes

Is it essential to maintain an effective fuel economy? Should the emission from the vehicle be less or more? Yes! The Powertrain Control module or the PCM has to maintain a fuel economy with less emissions so that the vehicle can reach a critical operating temperature between 160-170 degrees within 5 minutes as soon as the engine starts up. In extreme cold temperature, the coolant temperature must be at least 70+ degrees. If the coolant temperature wanders or does not reach this point, the PCM code will be set.

If the Powertrain Control module or the engine control module does not reach this temperature, it will be impossible to control the fuel economy and emission. The Engine Coolant temperature sensor has a reference voltage and ground, but the sensor makes the circuit complete. Resistance of thermal resistor will decrease, if engine coolant temperature increases. This mainly occurs as high voltage is input to the PCM. The circuit voltage will decrease when the engine coolant temperature decreases causing a reverse action. Some vehicles use multiple Engine Coolant temperature sensors. Secondary Engine Coolant temperature sensor is placed on the radiator tanks. The Powertrain Control module will compare input signal to check if the engine coolant is flowing effectively. Under cold conditions, engine coolant temperature is compared to ambient temperature. The ambient temperature is located near the grille.

What causes this problem with Cold Start Engine Coolant Temperature Performance?

• The primary or secondary Engine Coolant temperature sensor is damaged
• The ambient air temperature sensor is damaged
• The circuits and connectors are shorted or open
• Very poor thermostat low engine coolant

1. ECT Sensor - Visually inspect the primary and secondary Engine Coolant temperature sensor and replace if any damages are found.
2. Temperature sensor - A damaged temperature sensor will indicate wrong reading. Replace the component to obtain correct readings.
3. Circuits or sensor - Are you looking for a replacement for your circuits or sensors? Parts Avatar is the right place for parts of every model and make
4. Coolant temperature sensor - If the coolant temperature sensor is not upto the mark, it can harm the engine. Visually inspect the issue and fix them.

Interested in knowing the symptoms to OBD code P050C? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with Cold Start Engine Coolant Temperature Performance.

Common Symptoms

• Great Exhaust

Have a look at some ways with which you can correct the P050C code:

• Replacement of Engine Coolant temperature sensor
• Changing the temperature sensor
• Replacing the faulty circuits or sensor

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of Circuits or Connectors, Vacuum, Coolant Temperature (ECT), Sensor, CMP Sensor, Low Engine Coolant and many more. Now all your problems would vanish within no time.

Here are a few steps to diagnose the OBD code P050C:

• Make sure that the engine is cool and not overheated. Once it is made sure, now visually check the connectors and Engine Coolant temperature sensor wiring system.
• In order to diagnose this code, you need to have access to a reliable source of information, infrared thermometer with a laser pointer, diagnostic scanner and Digital Voltmeter / Ohmmeter.
• In order to accurately diagnose the P050C code you will need the diagnostic flowcharts, wire diagrams, connector face views, testing procedures of the component and specifications. You can also find this information in your vehicle’s manual.
• Connect the scanner to the diagnostic port of the vehicle and retrieve, freeze frame data and note it down in a safe place. It will be useful when you dive deep into the diagnostic process. Once the code is cleared, test drive again to see if the codes reappear.
• If the code returns immediately, turn the key on with engine off and connect the scanner again. With the infrared thermometer check the coolant temperature at the exact place near the Engine Coolant temperature sensor. Examine the Engine Coolant temperature data on the scanner and check if it includes only items for faster and more specific data response.
• Follow the diagnostic steps if it fails to match the original coolant temperature.

Common mistakes when diagnosing the P050C code

• Faulty coolant temperature sensor
• Low engine coolant level
• Faulty thermostat
