Guide To P2346 OBD Error Code Solutions
OBD Code P2346 - Cylinder 11 Above Knock Threshold
The piezoelectric element is used by the knock
sensor to identify the engine knocking which is also called as detonation or
pinging. This sensor is correctly fixed to the cylinder head, intake manifold
and the cylinder block. The cylinder block will produce a knocking vibration
and it is identified as vibrational pressure. This pressure will be sent forth
to the ECM once it is changed into a voltage signal. To slow down the timing of
the ignition, the ECM will utilize this signal and the engine is guarded
against this harmful pre-ignition.
Learn More About OBD Error Code P2346
The P2346 error code generally means that the ECM has found out that the knocking of the cylinder 11 is very high than the indicated limit even before the flashing of the check engine light.
What causes this problem with the Cylinder 11 Above Knock Threshold?
- The return signal from ECM cylinder #11 knock sensor shows that the cylinder might be knocking.
- If the cylinder is running lean on fuel from a clogged injector or if there are any other mechanical issues like a piston or bearing knock, the cylinder might be knocking.
- The octane levels might be low or the fuel might be weak.
Replace/Repair These Parts To Fix Code P2346
- Knock Sensor - If
the knock sensor is damaged, it will not allow the engine to accelerate
properly in the highway. Get rid of it as soon as possible.
- Cylinder Head Gasket - If
the cylinder head gasket is blown, then your car’s coolant can be leaking into
the oil pan. Change it instantly.
- Sensor Connector - Do
you find the sensor connector to be faulty? Is it broken? Get the right
replacement for your faulty sensor connector from Parts Avatar at the best
prices.
- Intake Manifold - If the intake manifold is faulty,
then the engine will start overheating. Fix it as quickly as possible to avoid
the P2346 error code.
- Engine Control Module - The engine performance will be poor
and there will be a drop in fuel economy if the ECM malfunctions. Replace it
immediately.
- Fuel Injector - Does your engine surge very often?
Then it is an indication that the fuel injector is faulty and it must be
replaced quickly.
- Spark Plug - If
the speed of the vehicle is slow as you drive uphill, then it is an indication
that the spark plugs are defective. Get rid of it quickly.
- Powertrain Control Module - The
PCM regulates important functions of the vehicle as well as it has a direct
impact on how well your vehicle performs. Fixing your faulty powertrain control
module (PCM) will help your engine to run smoothly.
Symptoms Of The OBD Error Code P2346
Well, if you are looking to know about the common symptoms related to this error code P2346, we are have worked out a small list to help you discover this error code with your vehicle.
Common Symptoms
- Illumination of the check engine light will take place and the code is set in the memory of the ECM as an issue.
- During acceleration, the engine error may show up a pinging sound.
- There might be a knocking noise in the engine which comes from #11 cylinder.
How To Correct P2346 Cylinder 11 Above Knock Threshold
Fixing problems with your car is not as easy as it might seem. You need to be extremely careful and follow certain steps.
- The fuel injector must be cleaned or repaired.
- The wires or the connection to the knock sensor assembly must be fixed or the sensor must be changed if faulty.
- Any internal mechanical issue to the #11 cylinder which caused the problem must be fixed.

Easy Diagnosis Of Engine Error OBD Code P2346
It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2346 code to be stored:
- As a very first step, each of the codes has to be scanned and documented in the engine control module.
- Once the codes are scanned, you have to diagnose them as per the pinpoint test which is specified by the manufacturer to check the sensor signal.
- The sensor detection of knock has to be checked to know as to what will happen if there are any mechanical or fuel related issues in the engine of the vehicle.
- Carefully listen to the noise if it is possible so that the component can be separated.
- Locate the reasons for the defective components.
- Give a knock which is near the sensor so that a knock can be initiated to check the sensor.
Common Mistakes When Diagnosing The P2346 Code
- Even before checking the freeze frame data for the failure, clearing the memory codes of the ECM, so the duplication of the failure can be made.
- Once the P2346 error code is fixed, failing to clear the ECM codes.
- Changing the sensor even before the duplication of the problem.
