The automobile fault code P2301 can be caused by a faulty ignition coil, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2301 can be caused by a faulty ignition coil ‘A’.
  • It can also be caused by an open or shorted ignition coil ‘A’ harness.
  • Additionally, a poor electrical connection in the ignition coil ‘A’ circuit can also trigger this fault code.

To fix the p2301 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2301, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2301 indicates an issue with the ignition coil A primary control circuit low. The estimated repair time for this issue is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the location of the repair shop, the make and model of the vehicle, and the severity of the issue.

The P2301 code is related to the ignition system of the automobile.

It indicates a problem with the primary control circuit of ignition coil ‘A’. The Powertrain Control Module (PCM) controls the current flow through the primary ignition coil.

The PCM detects a short to voltage in the circuit and sets the P2301 code.

This code can cause issues with the spark plug firing and should be addressed promptly.

What are the possible causes of the P2301 automobile fault code?

If you’re experiencing a rough running engine and the engine light is on, it could be due to the P2301 fault code. This code is caused by a faulty ignition coil ‘A’, an open or shorted harness, or a poor electrical connection in the ignition coil ‘A’ circuit. To fix the issue, inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

How can I visually inspect the related wiring harness and connectors to fix the P2301 fault code?

To fix the P2301 fault code, start by checking the possible causes listed above. Visually inspect the related wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector pins. This can help identify if the issue is caused by a faulty ignition coil ‘A’, an open or shorted harness, or a poor electrical connection in the ignition coil ‘A’ circuit.

What are the symptoms of the P2301 automobile fault code?

The P2301 fault code is indicated by the Engine Light ON or Service Engine Soon Warning Light and may cause the engine to run rough. The cause of this fault code is a faulty Ignition Coil ‘A’, an open or shorted harness, or a poor electrical connection in the circuit. To fix this issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

p2301 error fault code explained

If you see the Engine Light ON or Service Engine Soon Warning Light and the engine is running rough, it could be due to a faulty Ignition Coil ‘A’, an open or shorted harness, or poor electrical connection.

Check the wiring harness and connectors for damage and inspect the components for any issues.
