P0335 Nissan Code Meaning
The P0335 code indicates a malfunction in the crankshaft position sensor circuit in Nissan vehicles.
Common causes include a faulty sensor, damaged wiring, or corrosion.
Diagnosis involves inspecting the sensor and wiring.
Timely resolution is crucial to prevent further performance issues.
Error Code P0335 Symptoms
Symptoms of the P0335 error code can affect how a vehicle runs. When the crankshaft position sensor has issues, drivers may notice several problems that make driving difficult.
- Engine Misfires: The engine might misfire often. This happens because the bad sensor throws off the engine's timing, leading to uneven power.
- Rough Idling: Drivers may experience rough idling. This occurs when the Engine Control Unit (ECU) can't adjust timing correctly because of the faulty sensor.
- Difficulty Starting: Starting the engine can become hard. The sensor's failure affects the ignition timing needed for the engine to start properly.
Other signs include stalling while driving, which can be dangerous. The ECU needs accurate feedback from the crankshaft position sensor to keep the engine running smoothly.
Drivers may also notice worse fuel efficiency, as incorrect timing can lead to poor fuel combustion and higher fuel use. Addressing these issues quickly can help bring back good vehicle performance and avoid more serious problems down the line.
Causes of Nissan P0335 Fault Code
Understanding what can cause the Nissan P0335 fault code helps with diagnosing and fixing the problem. This code points to an issue with the crankshaft position sensor. Here are some common reasons it may appear:
- Faulty Crankshaft Position Sensor: The most common reason for the P0335 code is a problem with the crankshaft position sensor itself. If this sensor does not work correctly, it cannot track the crankshaft's position and speed, sending wrong information to the engine control unit (ECU).
- Damaged Wiring or Connectors: The wires and connectors for the sensor need to be in good shape. If they are damaged or corroded, the signal may not get through properly. This can lead to the ECU receiving incorrect signals, which triggers the fault code.
- Mechanical Damage: If the crankshaft position sensor gets physically damaged, it may not function well. This damage can happen from impacts, wear and tear, or incorrect installation, making it harder to find the issue.
Sometimes, problems with the engine control unit itself can also cause the P0335 code. Addressing these issues one by one will help diagnose and fix the problem effectively.
Tools Needed to Diagnose
To diagnose a crankshaft position sensor issue, you need some basic tools. Having the right tools makes it easier to find the problem and fix it accurately.
- Digital Multimeter: This tool measures the resistance and voltage of the crankshaft position sensor. It helps check if the sensor is working as it should according to the manufacturer's guidelines.
- OBD-II Scanner: This scanner reads and clears Diagnostic Trouble Codes (DTC) from the vehicle's computer. It gives real-time data and important information about any problems with the crankshaft position sensor.
- Basic Hand Tools: Tools like sockets, wrenches, and screwdrivers are needed to access and replace the crankshaft position sensor if it's faulty. Having a good set of tools helps the technician make repairs quickly.
Having a wiring diagram for the crankshaft position sensor circuit can help find any wiring problems.
Also, using safety gear like gloves and safety glasses is important for protection during the diagnostic process.
How to Fix P0335 Nissan Error Code – Step by Step
Step 1: Locate the crankshaft position sensor in your Nissan vehicle. It is typically found near the crankshaft pulley or flywheel.
Step 2: Inspect the wiring and connectors connected to the crankshaft position sensor. Look for any signs of damage such as fraying, corrosion, or loose connections that could interfere with the sensor's signal.
Step 3: Use a multimeter to test the crankshaft position sensor. Measure its resistance and voltage, ensuring that these values align with the manufacturer's specifications.
Step 4: If the sensor does not meet the required specifications, it is likely defective and should be replaced. When installing a new sensor, ensure that all connections are secure and the sensor is protected from contaminants.
Step 5: After replacing the crankshaft position sensor, clear the diagnostic trouble code (DTC) using an OBD-II scanner. This resets the vehicle's computer.
Common Diagnosis Mistakes
Misdiagnosing a P0335 error code can cause unnecessary repairs and longer vehicle downtime. To avoid mistakes, technicians should look at the whole picture.
Here are three common errors:
- Thinking the Sensor is the Only Problem: Some technicians quickly decide that a bad crankshaft position sensor is the only issue. They might forget to check for wiring problems or damaged connectors, missing other potential issues.
- Ignoring ECU Issues: The Engine Control Unit (ECU) can also trigger the P0335 code. If technicians overlook ECU problems, they might waste time and effort on the wrong repairs.
- Skipping Important Tests: Conducting resistance and voltage tests on the sensor is important. If these tests are skipped, technicians might replace sensors unnecessarily, wasting time and money.
It's also a good idea to check for corrosion or dirt at sensor connections to ensure everything is working properly.
P0335 Nissan Repair Cost
Fixing a P0335 error code on a Nissan vehicle can lead to different repair costs. For a 2006 Nissan Altima, the costs usually range from $100 to $300. This change in price depends on parts and labor.
The crankshaft position sensor replacement costs between $50 and $150. Labor is another key factor, with rates around $80 to $150 per hour. Diagnosing the issue can take one to two hours, which adds to the total cost.
Watch for extra costs that might come up. If there are problems like damaged wiring or issues with the Engine Control Unit (ECU), these will need fixing as well, which can raise the total bill. For example, fixing wiring could add another $100 to $200.
Getting quotes from several repair shops can help you find a fair price. Knowing these details helps with planning for the repairs linked to the P0335 code and getting the vehicle back in good condition.
Related Error Codes on Nissan
When a Nissan vehicle shows a P0335 code, it's important to check for other related error codes. These codes can help identify more problems within the engine management system.
Here are some error codes that might appear along with a P0335:
| Error Code | Description |
|---|---|
| P0336 | Crankshaft Position Sensor 'B' Circuit Range/Performance Problem |
| P0340 | Camshaft Position Sensor 'A' Circuit Malfunction |
| P0720 | Output Speed Sensor Circuit Malfunction |
| P0500 | Vehicle Speed Sensor Malfunction |
These codes suggest that the issues might extend beyond just the crankshaft position sensor. For example, P0336 relates to problems with the 'B' sensor, which may affect timing. P0720 indicates that the output speed sensor could also be impacted because these sensors often work together.
Additionally, if the crankshaft sensor fails, it can lead to issues with speed readings, which is reflected in the P0500 code. Checking all related error codes is necessary for a full assessment of the engine's sensor systems.
