How serious is the P250C engine code? 

While the P250C engine code might not seem like a major issue, it’s important that you deal with it as soon as possible. Inadequate lubrication or oil pressure can quickly cause irreparable damage to internal engine parts.

Can I fix the P250C engine code myself?

Attempting to fix the P250C engine code at home may be doable, but it's vital to first identify the problem. In some cases, you may need to do the following:
  • Visually inspect the wiring harness and connectors
  • Check for damaged components
  • Look for broken, bent, pushed out, or corroded connector’s pins
Doing these steps can help possibly fix your engine oil issues, but it’s best to bring it to a professional for a thorough diagnostic inspection and repairs.

Replacing the low oil level sensor

If you decide to replace the low oil level sensor by yourself, you can complete the following steps:
  • Jack up the vehicle and set it on jack stands. Place wheel chocks on both wheels still on the ground to make sure nothing moves during the repair.
  • Locate the low oil level sensor. It should be found on the side of the oil pan and will have an electrical connector coming out of it.
  • Unplug the electrical connector. You might have to push in and out a few times to release it.
  • Remove the low oil level sensor. There will be a fastener you’ll need to remove, which can be nuts, bolts, screws, or clips. You may lose some oil during this process, so place a drain pan underneath the area you’re working on.
  • Ensure you have the correct replacement part. Compare your recently-removed oil level sensor to your new one and make sure they’re the same dimensions and have the same electrical connectors.
  • Clean the area around the sensor mount. Make sure no dirt, debris, or oil will prevent the sensor from sealing to the oil pan.
  • Install the new low oil level sensor. You only need to tighten it enough to hold it in place, so be sure not to overtighten, as you risk breaking something.
  • Reconnect the electrical connector. Push it in far enough so the retaining clip can engage.
  • Remove the jack stands and refill the engine oil. Test drive your car to check for any possible leaks.
