how to fix P0301 misfire code in 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 battery to prevent electrical shorting.

2. Replace Spark Plug

• Tools Required: Spark plug socket, torque wrench, ratchet, extension.
• Remove the engine cover if applicable to access the spark plug.
• Use the spark plug socket to remove the old spark plug from cylinder 1.
• Inspect the old spark plug for wear; if damaged, replace it with a new one.
• Install the new spark plug by hand to avoid cross-threading, then torque to manufacturer specifications (typically 13-15 lb-ft).

3. Inspect and Replace Ignition Coil

• Tools Required: Ratchet, socket set.
• Disconnect the electrical connector from the ignition coil on cylinder 1.
• Remove the bolts securing the ignition coil and lift it out.
• Inspect the coil for cracks or damage. If faulty, replace it with a new ignition coil.
• Reinstall the new ignition coil, securing it with bolts to the specified torque.

4. Check Fuel Injector

• Tools Required: Noid light, multimeter.
• Disconnect the fuel injector connector on cylinder 1.
• Use a noid light to check for proper signal to the injector. If the noid light does not flash, further diagnostics on the wiring or ECM may be required.
• If the injector is faulty, remove it with a fuel injector removal tool and replace with a new injector.

5. Perform Compression Test

• Tools Required: Compression gauge.
• Remove the spark plug from cylinder 1 and screw in the compression gauge.
• Crank the engine and record the compression reading. Compare it to manufacturer specifications.
• If the reading is low, further investigation into the engine internals may be necessary.
