P2343: Ignition Coil ‘i’ Primary Control Circuit Low – Explained
The P2343 code is related to the Knock Sensor (KS) in the automobile engine.
The KS senses engine knocking using a piezoelectric element. The code indicates that Cylinder 8 is above the knock threshold, which means that there is a knocking vibration from the cylinder block. 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, the fault code P2343 may be the culprit. 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, 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 P2343 fault code, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
The P2343 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 possible causes of this fault code include 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).
