The P2340 automobile fault code indicates a problem with the knock sensor circuit, which can result in the engine light turning on and a possible lack or loss of power.
The cause of this issue could be a faulty knock sensor, poor electrical connection in the circuit, an open or shorted knock sensor harness, or a faulty Engine Control Module (ECM). It is important to visually inspect the wiring harness and connectors for any damage or corrosion. The repair time for this issue is estimated at 1.0, and it is crucial to address this problem promptly to avoid further damage to the vehicle.
To interpret the fault code, it is recommended to check the possible causes listed above and inspect the related components thoroughly.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 10.0 (Out of 10) |

P2340: Affordable Fix For Your Car’s Engine
The automobile fault code P2340 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 P2340 fault code will depend on the hourly rate charged by the repair shop and the time taken to complete the repair.
P2340: Ignition Coil ‘c’ Primary/Secondary Circuit Malfunction
The P2340 code indicates that the Knock Sensor has detected engine knocking in Cylinder 5. The Knock Sensor senses engine knocking using a piezoelectric element. The sensor is attached to the cylinder block, cylinder head or intake manifold.
A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (ECM).
The ECM uses this signal to retard the ignition timing and protect the engine from this damaging pre-ignition.
FAQ
If you’re experiencing a lack or loss of power and the engine light is on, it could be due to the P2340 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.
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 P2340 fault code, visually inspect the related wiring harness and connectors for any damage or corrosion. Check for broken, bent, or pushed out pins in the connectors. Don’t forget to examine the knock sensor harness for any open or shorted circuits.
The P2340 fault code in an automobile is indicated by the Engine Light ON or Service Engine Soon Warning Light. It may also result in a possible lack or 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 visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
Wrap Up
If your engine light is on and you’re experiencing a lack of power, it could be due to a faulty knock sensor, poor electrical connection, or a faulty ECM. Check the wiring harness and connectors for damage and inspect the components for any issues.
