When your vehicle’s engine stutters, your heart skips a beat. When your car refuses to start, you feel a pit in your stomach. These could be signs of a P0335 code – a crankshaft sensor malfunction.

This common automotive issue can be daunting, but you’re not alone in this. We’re here to support you, arming you with knowledge about the causes, symptoms, and most importantly, effective fixes for this issue.

Feel empowered and regain control over your vehicle’s health as we delve into the nitty-gritty of the P0335 crankshaft sensor malfunction.

Understanding Code P0335

Let’s dive into understanding what code P0335 really means for your vehicle’s performance and function.

The P0335: Crankshaft Position Sensor code indicates a malfunction within your vehicle’s crankshaft sensor circuit. This could stem from a myriad of issues: a damaged crankshaft sensor, a failed powertrain control module, issues with other sensors, a broken timing belt, or damaged reluctor rings.

Understanding code P0335 is key to diagnosing and fixing your vehicle’s problem. The crankshaft sensor plays a crucial role in your engine’s function. It provides the engine control unit (ECU) with precise information about the crankshaft’s speed and position. This data is vital as it affects fuel injection, ignition timing, and other engine functions.

When this sensor fails or has a circuit malfunction, it disrupts signal transference, causing a host of issues like misfires, difficulties starting the vehicle, and even the illumination of the malfunction indicator lamp (MIL).

Being familiar with this code and its implications allows you to belong to an informed group of vehicle owners. You’re not just reacting to problems, but actively understanding and addressing potential crankshaft sensor malfunctions and fixes.

Causes Behind P0335 Malfunction

There are several reasons you might encounter the P0335 malfunction in your vehicle. The most common cause is a damaged crankshaft sensor. This sensor plays a crucial role in monitoring your engine’s speed and position. If it’s compromised, your vehicle’s computer could throw the P0335 code, indicating a crankshaft sensor malfunction.

Another potential culprit is a failed Powertrain Control Module (PCM). This unit controls and coordinates the functioning of various sensors and systems within your vehicle. If it’s not working correctly, it can cause a range of issues, including the P0335 code.

Other sensors in your vehicle can also contribute to the P0335 malfunction. If these sensors provide inaccurate data or fail altogether, your vehicle could display the P0335 code. Similarly, mechanical issues such as broken timing belts or damaged reluctor rings are common causes behind P0335 malfunction. These components are integral to your engine’s operation, and any damage can lead to serious problems.

Recognizing P0335 Symptoms

Often, you’ll notice the symptoms of a P0335 malfunction before your vehicle’s computer registers the problem and illuminates the Malfunction Indicator Lamp (MIL). Recognizing P0335 symptoms early can prevent further damage, saving you from expensive repairs.

One of the most common signs of a P0335 crankshaft sensor malfunction is a misfire. You’ll feel the engine’s irregular rhythm, making your ride less smooth than usual. Due to the crank position sensor’s role in spark timing, a faulty sensor may also result in your vehicle’s inability to start. It’s as if your vehicle’s lost its spark, literally.

Another telltale sign is the MIL illuminating. This is your vehicle’s way of crying for help, alerting you to check the engine. However, in some cases, the check engine light may require multiple cycles to light up, especially when the crank sensor is used for spark timing.

Keep in mind, different vehicles may show different symptoms depending on how they use the crank sensor. So, don’t ignore anything unusual. It’s your vehicle’s way of communicating with you. By recognizing P0335 symptoms, you’re one step closer to pinpointing the problem and implementing the necessary fixes.

Professional Diagnosis Process

In your journey to fix a P0335 error, a thorough professional diagnosis is the first crucial step you’ll need to take. This process involves using a scan tool to check for an RPM signal when your car is running. It’s a crucial part of the Diagnostic Trouble Code (DTC) process that isolates the issue at hand.

Now, if the trouble persists despite your crank sensor appearing fine, an experienced mechanic may opt to use a scope tool for a more in-depth examination. This level of scrutiny forms part of the professional diagnosis process, ensuring that no stone is left unturned in search of the problem.

Keep in mind, loose wiring or connections could be causing your P0335 error. Hence, checking the integrity of these components forms an integral part of the diagnosis.

If the problem still isn’t apparent after your diligent troubleshooting, don’t hesitate to seek professional assistance. Companies like YourMechanic’s service team are equipped with the knowledge and tools to provide further diagnostic insight and resolution.

Effective Solutions for P0335

Once you’ve nailed down the diagnosis, it’s time to tackle the P0335 issue head-on with some effective solutions.

The P0335 code signifies a problem with the crankshaft position sensor. It’s a critical component that communicates the position of the crankshaft to your car’s computer, affecting how your engine runs.

Start by using a scan tool to check for an RPM signal while the vehicle is running. If the scan tool doesn’t read an RPM signal, it’s a strong indication that the sensor is faulty.

Next, inspect the crank sensor itself. Look for any signs of damage such as cracks, wear, or dislocation. It might be position 21 on your engine, depending on your model. If you identify any damage, replace the sensor right away.

Don’t forget to check the wiring and connections for any looseness or breakages, as this could trigger the P0335 code. Tighten loose connections and replace any damaged wires to ensure the sensor functions properly.

If you can’t diagnose the problem or if the error persists, it’s time to call in a professional. An experienced mechanic with a scope tool can pinpoint the issue more accurately.

This is a technical issue, but with the right approach, you can solve it.

Frequently Asked Questions

How Do I Fix Code P0335?

You’d check for an RPM signal, inspect the sensor, and fix any damage. Check wirings, too. If it’s tricky, consult a pro. Consider sensor replacement costs, DIY troubleshooting, P0335 code erasing, and professional help.

How Do You Temporarily Fix a Crankshaft Position Sensor?
