how to resolve P0301 code on Tesla Outback 6th Generation (2020-2024)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Spark Plug

• Tools Required: Spark plug socket, ratchet, torque wrench.
• Remove the ignition coil cover if applicable.
• Remove the spark plug using a spark plug socket.
• Inspect the spark plug for fouling, wear, or damage.
• If needed, replace the spark plug with OEM specification (typically gapped to 0.028-0.031 inches).
• Torque the spark plug to the manufacturer’s specification (usually around 13-15 lb-ft).

3. Test Ignition Coil

• Tools Required: Multimeter.
• Disconnect the ignition coil connector and remove the coil from cylinder 1.
• Check the primary and secondary resistance of the coil using a multimeter (consult the service manual for specific values).
• If the coil is faulty, replace it with an OEM part.

4. Check Fuel Injector

• Tools Required: Fuel pressure gauge, injector cleaner.
• Connect a fuel pressure gauge to the fuel rail.
• Turn the ignition to the "On" position (do not start) to check fuel pressure against specifications.
• If pressure is low, inspect the fuel pump or filter.
• Remove the fuel injector from cylinder 1 and clean or replace it if necessary.

5. Perform Compression Test

• Tools Required: Compression tester.
• Remove the spark plug from cylinder 1.
• Insert the compression tester into the spark plug hole and crank the engine for several seconds.
• Compare the reading to manufacturer specifications; if low, further inspection of the piston rings and valves may be necessary.

6. Inspect for Vacuum Leaks

• Tools Required: Smoke machine or carburetor cleaner.
• Visually inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
• Use a smoke machine to identify any leaks, or spray carburetor cleaner around suspected areas and listen for changes in engine RPM.
