By Ezra Lane You're dealing with the P1335 Nissan code, signaling an electrical fault in the Crankshaft Position Sensor (POS) Circuit. This fault directly impacts your vehicle's engine functionality by disrupting fuel injection and ignition timing, potentially causing stalling, rough idling, and inaccurate engine speed readings. Promptly addressing this issue is vital. Check the sensor and its connection for damage or corrosion, and ensure the wiring and engine control module (ECM) aren't contributing to the fault. Consider repairs like replacing the sensor or updating the ECM. With these fixes, your vehicle's performance can be substantially improved and other insights could further enhance your understanding.
P1335 Nissan Code Meaning
P1335 Nissan code indicates an electrical fault in the Crankshaft Position Sensor circuit, affecting fuel injection and ignition timing.
Inspect for damaged wiring or a faulty sensor.
Test and replace if needed to resolve performance issues and clear the code.
Error Code P1335 Symptoms
When you see the P1335 Nissan code, your car might show some clear signs. These signs are linked to problems with the crankshaft position sensor, which helps manage the engine. Spotting these early can stop bigger problems later.
- Unsteady Engine: The engine mightn't run smoothly. You could face sudden stops, misfires, or trouble starting. This happens because the engine control unit can't read the crankshaft's position correctly.
- Check Engine Light: The check engine light on your dashboard may light up. This happens when the engine control module gets wrong information from the crankshaft position sensor.
- More Fuel Use: Your car might use more fuel than normal. This can occur because the engine timing is off due to a bad sensor.
- Rough Idling: If the engine shakes or is unsteady when idling, it could mean engine timing issues due to the P1335 error.
- Slow Acceleration: Your car might hesitate or struggle to speed up, which relates to engine timing problems from a bad sensor.
Causes of Nissan P1335 Fault Code
Many things can cause the P1335 error code in your Nissan. This code is about problems with the crankshaft position sensor's circuit, which affects how your engine runs. Knowing what might cause this code can help you fix the issue.
Here are some common reasons:
- Bad crankshaft sensor: The sensor might be broken or not working properly.
- Wiring problems: The wires in the crankshaft sensor's circuit might be broken, shorted, or corroded.
- Loose connections: Weak connections in the sensor's circuit can mess up the signal.
- Issues with control module: The engine control module (ECM) mightn't be working right, which affects the sensor.
- Magnetic interference: Outside magnetic fields might disturb the sensor's work.
These problems stop the crankshaft position sensor from sending correct data to your Nissan's ECM. The ECM needs this information to handle engine timing and fuel injection.
Identifying the specific problem is key to fixing it and keeping your car running smoothly.
Tools Needed to Diagnose
To figure out what's wrong with the P1335 code in a Nissan, you'll need some tools. These tools help you check if the crankshaft position sensor is working right or if it needs to be changed. Without them, you mightn't catch some problems or might think something else is wrong.
Here's what you'll need:
- OBD-II Scanner: This tool reads the codes from your car's computer.
- Digital Multimeter: It measures the voltage and resistance in the sensor's wires.
- Oscilloscope: This lets you see the signals from the sensor.
- Signal Simulator: It mimics sensor signals to check how the ECU reacts and tests the circuit and sensor.
- Basic Hand Tools: Things like screwdrivers and wrenches, useful for getting to and removing the sensor if needed.
These tools help you find out what's causing the P1335 error code. The scanner gives you the error codes; the multimeter and oscilloscope help you check the wires and signals. The signal simulator and hand tools are helpful for testing and making adjustments.
Make sure you have these tools ready for the job.
How to Fix P1335 Nissan Error Code – Step by Step
Step 1:
Begin by confirming that the crankshaft position sensor (POS) is the cause of the P1335 error code. This sensor plays a critical role in monitoring the position and rotational speed of the crankshaft, which the engine control unit (ECU) uses to adjust timing and fuel injection.
Step 2:
Locate the crankshaft position sensor, which is typically situated near the bottom of the engine block. Inspect the sensor and its connector for any visible signs of damage or corrosion. If any issues are present, the sensor will need to be replaced.
Before proceeding, disconnect the battery to ensure safety.
Step 3:
Carefully remove the faulty sensor by unscrewing it from the engine block. Pay close attention to its orientation and how it fits into place to ensure proper installation of the new sensor.
Step 4:
Install the new crankshaft position sensor, making sure it's securely fastened and correctly aligned. Reconnect the wiring harness, ensuring a firm and stable connection to avoid future faults.
Step 5:
After installing the new sensor, reconnect the battery and start your Nissan. Use a diagnostic scanner to clear any existing error codes and verify that the new sensor is functioning properly.
If the P1335 code is cleared, take your vehicle for a test drive to confirm the fix. If the problem persists, further diagnostics may be necessary to identify any additional underlying issues.
Common Diagnosis Mistakes
Mechanics often misdiagnose the P1335 Nissan error code by not considering simpler problems that act like sensor failures. Instead of assuming the crankshaft position sensor is broken, look for other causes that might trigger the error code. This can help avoid unnecessary repairs and costs.
Common mistakes to avoid:
- Ignoring wiring problems: Bad wiring or loose connections can show the same signs as a bad sensor.
- Not checking battery voltage: Low voltage can make the sensor act like it's failing.
- Overlooking engine problems: Issues like engine misfires can affect sensor readings.
- Skipping software updates: Sometimes, a software update for the engine control module can fix the problem.
- Dismissing environmental factors: Dirt, oil, or debris on the sensor can mess up its readings.
Before assuming a major issue, check these areas first. This can save time and money and ensure you're fixing the right problem.
Always start with the simple checks before moving to more complex ones.
P1335 Nissan Repair Cost
Before you fix the P1335 issue in your Nissan, know what it might cost. The problem usually involves the crankshaft position sensor. Depending on your car and the mechanic's charges, the sensor can cost between $120 and $250.
Labor can range from $50 to $150, depending on how complex your engine is.
Don't forget about the diagnostic fee. Even if you get the repair done at the same place, you might still pay this fee, usually between $50 and $100.
So, in total, you might spend anywhere from $220 to $500.
Picking a skilled mechanic can help you avoid extra costs. Using parts from the original maker might be more expensive at first but could last longer and work better.
Double-check the problem before fixing it to avoid unnecessary expenses.
