How come my ezgo oil pressure light is flashing?

I’m not sure why my 2019 EZGO’s oil pressure light won’t stop flashing, and it’s freaking me out. Is this a sign of a major engine problem? Has anyone fixed this issue before? I could really use some advice before this turns into a bigger problem.


I had the oil light come on and flash too on my golf cart. It just turned out being a sensor issue. Replacing the oil pressure sensor solved everything for me.

  • Persistent flashing of the oil pressure light on the dashboard.
  • Possible performance issues or difficulty in starting the cart.

Possible Causes

  • A malfunctioning oil pressure sensor.
  • Low oil pressure due to internal engine problems.
  • Electrical issues, such as poor grounding in the oil light circuit.

Detailed Solutions that Worked

  1. Replacing the Sensor
    • What I Did: Swapped out the old oil pressure sensor with a new one.
    • Outcome: The annoying flashing light finally stopped, and the cart’s performance was back to normal.
    • Personal Experience: I was initially hesitant but found the sensor replacement to be a simpler fix than anticipated.
    • Estimated Cost: $20 – $50
    • Time Needed: 30 – 60 minutes
    • Detailed Steps:
      1. Identify the Sensor Location: Find the oil pressure sensor, usually near the oil filter or on the engine block.
      2. Safety First: Disconnect the battery to prevent any electrical hazards.
      3. Remove the Old Sensor: Carefully unscrew or unclip the old sensor. You might need a wrench or pliers for this.
      4. Install the New Sensor: Screw in the new sensor firmly but without over-tightening.
      5. Reconnect Everything: Reattach any wires or clips and reconnect the battery.
      6. Test Run: Start the engine to check if the light has stopped flashing.
    • Expert Tip: Apply some thread sealant on the new sensor’s threads to prevent oil leaks. Also, be gentle when handling the sensor as they can be quite fragile.
  2. Installing a Mechanical Oil Pressure Gauge
    • What I Did: Added a mechanical gauge for real-time oil pressure monitoring.
    • Outcome: Now I can keep an eye on the oil pressure, ensuring my engine’s health.
    • Personal Experience: The installation was a bit challenging but worth the peace of mind.
    • Estimated Cost: $50 – $100
    • Time Needed: 60 – 120 minutes
    • Detailed Steps:
      1. Select the Right Gauge: Choose a gauge that is compatible with your golf cart’s engine.
      2. Find the Perfect Spot: Decide where on your dashboard you want the gauge.
      3. Install the Gauge: Follow the manufacturer’s instructions to mount the gauge.
      4. Connect to the Oil Line: Route the tubing from the gauge to the engine’s oil pressure port.
      5. Secure All Connections: Ensure all fittings are tight to prevent leaks.
      6. Test the Setup: Start the engine and observe the gauge for accurate readings.
    • Expert Tip: Consider using Teflon tape on the threads of the tubing connections to ensure a leak-free installation. Also, make sure the gauge is easily visible while driving for constant monitoring.
