Understanding P0335 Code – Knock Sensor 2 Circuit Intermittent (Bank 2)
If you own a vehicle, you probably know how important it is to keep it in good condition. Every car has its own set of problems, and one of the most common issues is the P0335 code.
This code indicates that the knock sensor 2 circuit is intermittently malfunctioning in bank 2. If you’ve never heard of this before, don’t worry, we’ve got you covered.
In this article, we’ll discuss everything you need to know about the P0335 code, including its causes, symptoms, and how to fix it.
What is the P0335 Code?
The P0335 code is a diagnostic trouble code that indicates that the engine control module (ECM) has detected a problem with the knock sensor 2 circuit in bank 2. This code is typically found in vehicles with a V6 or V8 engine, but it can also occur in other types of engines.
What are the Causes of the P0335 Code?
There are various reasons why the P0335 code may appear. Some of the most common causes include:
- Faulty Knock Sensor: If the knock sensor is malfunctioning, it can send false signals to the ECM, causing the P0335 code to appear.
- Wiring Issues: Damaged wiring or loose connections can also cause the P0335 code to appear.
- Failed ECM: In rare cases, a failed ECM can be the reason behind the P0335 code.
What are the Symptoms of the P0335 Code?
The P0335 code may not always cause noticeable symptoms in your vehicle. However, some common symptoms include:
- Check Engine Light: The most obvious symptom of the P0335 code is the check engine light. When the ECM detects a problem with the knock sensor 2 circuit, it will trigger the check engine light.
- Poor Engine Performance: If the knock sensor isn’t functioning correctly, it can cause your engine to run poorly. This can result in reduced power, rough idling, and decreased fuel economy.
- Engine Misfiring: A malfunctioning knock sensor can cause your engine to misfire, leading to a rough running engine.
How to Fix the P0335 Code?
The best way to fix the P0335 code is to take your vehicle to a qualified mechanic. They will use a diagnostic tool to identify the exact cause of the problem. If the knock sensor is the issue, it will need to be replaced. Additionally, any damaged wiring or loose connections will need to be repaired or replaced. In some rare cases, the ECM may need to be replaced.
The P0335 code can be a frustrating issue to deal with, but it’s essential to address it as soon as possible. Ignoring the problem can cause further damage to your vehicle and result in costly repairs. If you notice the check engine light is on or experience any of the symptoms listed above, take your car to a qualified mechanic as soon as possible.
