how to fix the P0301 engine code on Tesla Outback 5th Generation (2015-2019)

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Spark Plug

• Remove the engine cover (if applicable) using a socket set.
• Locate the spark plug for cylinder 1.
• Use a spark plug socket to remove the spark plug.
• Inspect the spark plug for signs of wear or damage (e.g., carbon buildup, cracks).
• If damaged, replace with a new spark plug, ensuring it is gapped correctly (typically 0.028-0.032 inches).
• Reinstall the spark plug and torque to manufacturer specifications (usually around 12-15 lb-ft).

3. Test and Replace Ignition Coil

• Disconnect the ignition coil connector for cylinder 1.
• Remove the ignition coil using a socket set.
• Check the resistance of the ignition coil with a multimeter (should be within manufacturer specifications; typically around 0.4-1.0 ohms).
• Replace the ignition coil if it is out of spec.
• Reinstall the ignition coil and reconnect the electrical connector.

4. Check Fuel Injector

• Remove the fuel injector connector for cylinder 1.
• Perform a fuel injector balance test using a fuel pressure gauge (check for flow and pressure).
• If the injector is clogged, clean it using a specialized injector cleaner or replace it if necessary.
• Reinstall the fuel injector and ensure the connector is secure.

5. Compression Test (if needed)

• Remove the spark plug for cylinder 1 again.
• Insert a compression tester into the spark plug hole.
• Crank the engine and record the compression reading (should be within manufacturer specifications; typically around 120-200 psi).
• If compression is low, further investigation is needed (e.g., check for valve issues, head gasket failure).
