what does code P0302 mean for my Toyota Camry Eighth Generation (2018-present)

Solution

1. Preparation

• Gather tools and parts needed for repairs.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool before starting work.

2. Inspect Spark Plug and Ignition Coil

1. Remove Engine Cover (if applicable)
   • Use a socket set to remove any bolts securing the cover.
2. Remove Spark Plug
   • Use a spark plug socket to carefully unscrew and remove the spark plug from cylinder 2.
   • Inspect the spark plug for wear or carbon deposits and replace if necessary.
3. Check Ignition Coil
   • Disconnect the electrical connector from the ignition coil.
   • Remove the ignition coil using a socket set.
   • Test the coil with a multimeter to ensure it is functioning properly. Replace if faulty.

3. Inspect Fuel Injector

1. Remove Fuel Injector Connector
   • Disconnect the connector from the fuel injector in cylinder 2.
2. Test Fuel Injector
   • Use a multimeter to check for resistance; compare with specifications.
   • If the injector is faulty, replace it.

4. Perform Compression Test

1. Remove Spark Plug from Cylinder 2
   • Repeat the spark plug removal process if not yet done.
2. Connect Compression Tester
   • Insert the compression tester into the spark plug hole.
3. Crank the Engine
   • Have an assistant crank the engine while you monitor the gauge.
4. Record Compression Reading
   • Compare the reading with manufacturer specifications. If low, further diagnosis may be needed for internal engine components.

5. Inspect for Vacuum Leaks

1. Visual Inspection
   • Check all vacuum lines connected to the intake manifold for cracks or disconnections.
2. Use Smoke Test (if necessary)
   • Introduce smoke into the intake system to identify leaks.
