what does a P0302 code mean for my Tesla Model 3 Highland (2024-present)

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the vehicle's battery to ensure safety while working on electrical components.
• Allow the engine to cool down if it has been recently operated.

2. Inspect and Replace Ignition Components

• Tools Required: Socket set, torque wrench, ignition coil puller (if needed).
• Remove the engine cover (if applicable) to access the ignition components.
• Disconnect the electrical connector from the ignition coil for cylinder 2.
• Remove the bolts securing the ignition coil and gently pull it out.
• Inspect the spark plug for wear. If needed, replace spark plug with the specified part for the Tesla Model 3.
• Install the new spark plug and torque it to the manufacturer's specifications (usually around 13-15 lb-ft).
• Reinstall the ignition coil for cylinder 2, ensuring it is seated properly and reconnect the electrical connector.

3. Inspect and Clean Fuel Injector

• Tools Required: Fuel injector removal tool, cleaning solvent.
• Disconnect the fuel lines (using proper safety precautions to avoid fuel spills).
• Remove the fuel injector for cylinder 2.
• Clean the injector using a specialized cleaning solvent or replace it if it is clogged or damaged.
• Reinstall the fuel injector and reconnect the fuel lines securely.

4. Perform Compression Test

• Tools Required: Compression tester.
• Remove the spark plug for cylinder 2.
• Insert the compression tester into the spark plug hole.
• Crank the engine and observe the compression reading. Compare it to manufacturer specifications.
• If the compression is below the acceptable range, further investigation into engine internals may be needed.
