P250C - OBD Trouble Code

<<See All OBD Codes

The trouble code P250C can be defined as Engine Oil Level Sensor Circuit Low. The engine oil level sensor circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the engine oil level sensor circuit would not be as per the specifications set by the manufacturer.

1. Oil Level Sensor - If there are some flaws in your oil level sensor, then your car might not start at all. This sensor is designed to be an alert only device, but if the sensor is sending wrong data, then it would give rise to this fault code and would cause the engine’s ECU to not permit the engine to start. So it is very important to replace the oil level sensor with us at equitable prices.
2. Engine Control Module - It is not always the components, but the ECM that can also be faulty. It can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
3. Oil Pressure Gauge - If you find out that your oil pressure gauge is not working properly, then you must change the oil. If even after that the issue is not solved, then you can always rely on us as we have best auto parts for our customers.
4. Powertrain Control Module - Powertrain Control Module can also be faulty in rare cases and thus needs through checks for system and software errors. Thus check and replace it, if required.
5. Electronic Control Unit - The ECU manages the cooling system to control the battery operating temperatures and thus must be replaced, if found faulty. Thus, buy new ECU modules and components from us!
6. Diagnostic Tool - Make use of quality diagnostic tools to resolve any OBD error code. Buy quality diagnostic tools from us!

Common Symptoms

• Visibility in the check engine light
• Auto engine might not start at all
• There might be less oil pressure gauge reading

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P250C:

• You must change the oil and filter
• Make sure to mend the faulty connectors
• It is essential to restore the flawed engine oil level sensor
• Repair or replace the quirky ground straps
• Rehabilitate the defaults in the wiring
• Carefully adjust the faults in the PCM
• The fuse or fuse-able link should be restored to working order

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

A technician begins by hooking the vehicle to an OBD-II scanner to verify that the code is present, and check for other codes. The freeze frame data along with current data is recorded, and the codes are then cleared to see if they reoccur. After that the next step is to inspect the condition of the engine oil and confirm it is serviced to the appropriate level. Then all the constituents which are related with the engine oil level sensor circuit should be located and search for obvious physical damage. Depending on the particular vehicle, this circuit may incorporate several components including the oil pressure sensor, switches, fault indicators, an oil pressure gauge and the PCM.

You must perform a thorough visual inspection to inspect the related wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots. After that inspect the connectors and connections for security, corrosion and damaged pins. This process must include all wiring connectors and connections to all constituents including the PCM. Consult the specific tech data for the vehicle to verify the configuration of the oil level safety circuit and see if a fuse or fuse-able link is incorporated into the circuit.

The advanced steps become very automobile specific and need the appropriate advanced equipment to perform correctly. These procedures require a digital multimeter and the specific technical references for the vehicle. Now in this case, an oil pressure gauge may also be needed to assist the process of troubleshooting. The reference voltage and the acceptable ranges might differ depending upon on the particular vehicle and the circuit configuration. Particular technical data will include troubleshooting charts and the appropriate sequence to follow assisting you with correct diagnosis.

Now if an absence of a power source or ground is identified in this process, then there would be a need of continuity testing to inspect integrity of the wiring, connectors and other constituents. Make sure to perform continuity tests with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance. Resistance or no continuity would indicate that there are some faults in the wiring, so it should be repaired or restored. Then a continuity test should be performed from the PCM or ECM to the frame will confirm the serviceability level of ground straps and ground wires. The presence of resistance would indicate that the connection is loose or there is corrosion.

Common Mistakes When Diagnosing The P250C Code

• Many a times the technicians might simply replace the engine oil level sensor, when it reality the issues are with the wiring or connections which are giving rise to this error code.
