why is my Toyota Corolla E140 (2006-2013) oil light flashing while driving?

Solution

1. Preparation

• Gather all tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Check and Add Oil

• Tools Required: Oil funnel, correct type of engine oil.
• Remove the oil filler cap and add oil if the level is low, using the manufacturer-recommended oil type.
• Replace the oil filler cap securely.

3. Replace Oil Filter (if necessary)

• Tools Required: Oil filter wrench, socket set.
• Locate the oil filter, usually positioned on the bottom side of the engine.
• Use the oil filter wrench to remove the old filter; ensure the rubber gasket comes off with it.
• Apply a small amount of new oil to the rubber gasket of the new filter and install it, tightening it by hand until snug.

4. Oil Pressure Sending Unit Replacement (if faulty)

• Tools Required: Socket set, torque wrench.
• Locate the oil pressure sending unit, typically near the oil filter.
• Disconnect the electrical connector and remove the unit using a socket.
• Install the new oil pressure sending unit and tighten it to the manufacturer's specified torque.
• Reconnect the electrical connector.
