The P2346 fault code in automobiles refers to a possible lack or loss of power, indicated by the engine light or service engine soon warning light turning on. This issue is caused by a faulty knock sensor, poor electrical connection in the knock sensor circuit, or a faulty Engine Control Module (ECM).

The repair importance of this issue is high as it can lead to reduced engine performance and fuel efficiency. The repair difficulty is moderate, with a repair time of 1.0. To fix this issue, one must visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

  • The P2346 fault code in an automobile can cause the following symptoms: the engine light will turn on or the service engine soon warning light will appear.
  • There may be a possible lack or loss of power in the vehicle.
  • These are the only symptoms associated with this particular fault code.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P2346 fault code can be caused by a faulty knock sensor, poor electrical connection, open or shorted harness, or a faulty ECM.

  • The automobile fault code P2346 can be caused by a faulty knock sensor.
  • It can also be caused by a knock sensor circuit with poor electrical connection.
  • Another cause can be an open or shorted knock sensor harness.
  • Lastly, a faulty Engine Control Module (ECM) can also trigger this fault code.

To fix the p2346 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2346, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2346 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops. Therefore, the total cost of diagnosis and fixing the P2346 fault code will depend on the hourly rate charged by the repair shop and the time taken to complete the repair.

The P2346 code is related to the Knock Sensor (KS) in the engine.

The KS detects engine knocking using a piezoelectric element. The sensor is attached to the cylinder block, cylinder head or intake manifold.

The code indicates that cylinder 11 is experiencing knocking above the threshold. The ECM uses this signal to retard the ignition timing and protect the engine from pre-ignition damage.

What are the possible causes of the P2346 fault code in an automobile?

If you’re experiencing a lack or loss of power and the engine light is on, it could be due to the P2346 fault code. This code is often caused by a faulty knock sensor, poor electrical connection in the knock sensor circuit, an open or shorted knock sensor harness, or a faulty Engine Control Module (ECM). To fix the issue, it’s important to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

How can one visually inspect the related wiring harness and connectors to fix the P2346 fault code?

If you’re experiencing a lack or loss of power and your engine light is on, it could be due to a faulty knock sensor or poor electrical connection. To fix the P2346 fault code, check the possible causes and visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

What are the symptoms of the P2346 fault code in an automobile?

The P2346 fault code in an automobile is indicated by the Engine Light ON (or Service Engine Soon Warning Light) and possible lack/loss of power. The cause of this fault code could be a faulty knock sensor, poor electrical connection in the knock sensor circuit, an open or shorted knock sensor harness, or a faulty Engine Control Module (ECM). To fix this issue, one should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
