Another error code that, depending on the identified underlying cause, may call for professional intervention. When the crankshaft position sensor in your vehicle experiences an operational failure, the engine control module (PCM) records a P0335 code. The good news is that your Check Engine Light will most likely turn on immediately if the PCM notices this issue. The majority of car owners are unaware of the crankshaft position sensor unless they experience an engine failure or the error number P0335. The meaning of the code, symptoms to watch for, typical causes, and a solution are given below.
What Does Code P0335 Mean? (Rich Snippet)
Let’s discuss, What is code P0335?
P0335 is a generic diagnostic trouble code (DTC) that indicates a problem with the crankshaft position sensor circuit. The crankshaft position sensor is responsible for monitoring the speed and position of the engine’s crankshaft. When the sensor detects a problem, it sends a signal to the engine control module (ECM), which triggers the P0335 code and activates the Check Engine light.
A variety of issues, including a faulty sensor, damaged wiring, a faulty reluctor ring on the crankshaft, or a problem with the ECM, can cause the P0335 code. Symptoms of this code may include poor engine performance, stalling or hesitation during acceleration, and rough idling.
When the P0335 code is triggered, it is important to have the issue diagnosed and repaired as soon as possible. Ignoring this code can lead to further damage to your engine or other components, which can be costly to repair.
Faulty Symptoms of a P0335 Code
So, before fixing the problem, let’s first understand some common symptoms that can trigger P0335 DTC. Here are the signs:
Check Engine Light:
The most obvious symptom of a P0335 code is the illumination of the Check Engine light on your vehicle’s dashboard. This light may appear as a solid light or a flashing light, depending on the severity of the issue.
Poor engine performance:
Another symptom of a P0335 code is poor engine performance, including rough idling, stalling, or hesitation during acceleration. It is because the ECM relies on the crankshaft position sensor to determine the engine’s timing and fuel delivery.
If the crankshaft position sensor is not working correctly, it may be difficult to start your vehicle. It is due to the dependency of the ECM on the sensor to determine the engine’s position before it can deliver the correct amount of fuel and spark.
Reduced fuel economy:
A P0335 code can also cause reduced fuel economy as the engine struggles to maintain its optimal performance. If left unrepaired, this can lead to higher fuel costs over time.
If you notice any of these symptoms on your vehicle, it is important to have the issue diagnosed and repaired as soon as possible. Ignoring a P0335 code can lead to further damage to your engine or other components, which can be costly to repair.
How to Fix P0335 Code in a Crankshaft Position Sensor?
There must be a question in your mind. How do I fix code p0335? Although P0335 is a generic error code, the corrective actions may differ based on the underlying issue and the make and model of your car.
Here are some steps you can take to fix the P0335 code:
Check the wiring:
Start by inspecting the wiring harness and connectors for damage or corrosion. Look for frayed wires, loose connections, or signs of moisture intrusion. If you find any issues, repair or replace the affected components as necessary.
Check the sensor:
Use a multimeter to test the resistance of the crankshaft position sensor. However, the sensor should have a specific resistance range, which you can find in your vehicle’s service manual. If the sensor’s resistance is outside of this range, it may be faulty and need to be replaced.
Check the reluctor ring:
The reluctor ring is a toothed wheel on the crankshaft that the crankshaft position sensor uses to detect engine speed and position. If the wheel is damaged or missing teeth, the sensor won’t be able to detect the crankshaft’s position accurately. Inspect the reluctor wheel for damage and replace it if necessary.
Check the ECM:
If all of the above steps check out, the problem may lie with the engine control module (ECM). In some cases, the ECM may not be receiving the signal from the crankshaft position sensor due to a fault in the ECM or its wiring. You may need to have the ECM inspected and replaced by a qualified mechanic.
However, the P0335 code can be caused by a variety of issues, from damaged wiring to a faulty sensor or ECM. By following these steps, you can diagnose and fix the problem, which will help keep your engine running smoothly and prevent further damage to your vehicle.
Cost to Fix P0335 Code
The cost of fixing a P0335 code can vary depending on the root cause of the issue. Some possible causes of this code include a faulty crankshaft position sensor, damaged wiring or connectors, a faulty reluctor wheel, or a problem with the engine control module (ECM).
If the issue is a faulty crankshaft position sensor, the cost to replace the sensor can range from $100 to $250, including labor costs. If the issue is with the wiring or connectors, the cost to repair or replace these components will depend on the extent of the damage and the amount of time required for the repair. A simple repair could cost as little as $50, while a more extensive repair could cost up to $500.
If the issue is with the reluctor wheel or the engine control module (ECM), the cost to repair or replace these components can be significantly higher. The reluctor wheel is located on the crankshaft and can be challenging to access. It means that the cost of repair can range from $500 to $1000. Similarly, if the issue is with the ECM, the cost to replace the module can range from $500 to $1000, including labor costs.
It is essential to have the issue diagnosed correctly to ensure that the correct repairs are made. Ignoring a P0335 code can lead to further damage to your engine or other components, which can be even more costly to repair.
P0335 code – FAQs
P0335 is a diagnostic trouble code (DTC) indicating a crankshaft position sensor circuit malfunction.
Several possible causes of a P0335 code include a faulty crankshaft position sensor, a damaged sensor wiring harness, a poor electrical connection to the sensor, a malfunctioning PCM (powertrain control module), or a damaged crankshaft reluctor wheel.
The symptoms of a P0335 code can vary depending on the vehicle. But may include rough idling, stalling, poor acceleration, decreased fuel efficiency, and difficulty starting the engine.
Diagnosing a P0335 code involves using a scan tool to read the code and check for related codes. Checking the crankshaft position sensor and wiring for damage, testing the electrical connections to the sensor, and testing the PCM.
Fixing a P0335 code typically involves replacing a faulty crankshaft position sensor. Repairing a damaged sensor wiring harness or electrical connection. In some cases, a damaged reluctor wheel or malfunctioning PCM may also need to be replaced.
