When it comes to Subaru P0302 Code, it is a cylinder 2 misfire detected code. This can cause major engine issues such as stalling, improper idling, and rough driving. These issues can start as soon as the engine is started and can worsen when the vehicle reaches a speed of over 3 mph. This code can be caused by several different factors, such as wiring harness between the ECM and fuel injector connector needing repair, faulty fuel injector, poor contact of ignition coil connector, poor contact of fuel injector connector, poor communication in ECM connector, poor connection of coupling connector, loose camshaft position sensor, damaged crank sprocket, timing belt out of alignment, loose or damaged air intake system parts, or damaged spark plug or spark plug wire. It is important to be aware of these causes and solutions to address the issue of the Subaru P0302 Code.

Poor Contact of Ignition Coil Connector
The poor contact of the ignition coil connector can also cause the Subaru P0302 Code. If the connection is poor, it can cause the engine to misfire and trigger the code. To resolve this issue, check the contact of the ignition coil connector and repair or replace if necessary.
Poor Contact of Fuel Injector Connector
The poor contact of the fuel injector connector can also cause the Subaru P0302 Code. If the communication is poor, it can cause the engine to misfire and trigger the code. To resolve this issue, check the connection of the fuel injector connector and repair or replace it if necessary.
Loose Camshaft Position Sensor
The loose camshaft position sensor can be the source of the Subaru P0302 Code. If the camshaft position sensor is open, it can cause the engine to misfire and trigger the code. This can be resolved by tightening the camshaft position sensor.
Damaged Crank Sprocket
The damaged crank sprocket can also cause the Subaru P0302 Code. If the crank sprocket is damaged, it can cause the engine to misfire and trigger the code. This can be resolved by replacing the damaged crank sprocket.
Timing Belt Out of Alignment
The timing belt out of alignment can be the source of the Subaru P0302 Code. If the timing belt is out of alignment, it can cause the engine to misfire and trigger the code. This can be resolved by realigning the timing belt.
Loose or Damaged Air Intake System Parts
The loose or damaged air intake system parts can also cause the Subaru P0302 Code. If the air intake system parts are loose or damaged, it can cause the engine to misfire and trigger the code. This can be resolved by tightening or repairing/replacing the air intake system parts.
Damaged Spark Plug or Spark Plug Wire
The damaged spark plug or wire can also cause the Subaru P0302 Code. If the spark plug or spark plug wire is damaged, it can cause the engine to misfire and trigger the code. This can be resolved by replacing the damaged spark plug or spark plug wire.
Conclusion
In conclusion, the Subaru P0302 Code can be caused by several different factors. The most common causes are a wiring harness between the ECM and fuel injector connector needing repair, faulty fuel injector, poor contact of ignition coil connector, poor communication of fuel injector connector, loose camshaft position sensor, damaged crank sprocket, timing belt out of alignment, loose or damaged air intake system parts, or damaged spark plug or spark plug wire. It is important to be aware of these causes and solutions to address the issue of the Subaru P0302 Code.
