What does engine code p0335 mean?

The diagnostic trouble code P0335 indicates a malfunction with your vehicle’s crankshaft position sensor. This sensor monitors the position and rotational speed of the crankshaft. It relays this information to the vehicle’s engine control unit (ECU). The ECU detects an irregular reading from the crankshaft position sensor. It triggers code PO335. This often means the sensor itself has become defective or damaged. Without a functioning crankshaft position sensor, your vehicle’s engine cannot operate.

PO335 Error Code: Causes, Solutions, and Preventative Measures

As a vehicle owner, encountering a check engine light can provoke annoyance and dread. You recognise that it indicates a vehicle problem needing attention. Yet, you may feel unsure of its seriousness or cause. The code P0335 indicates an issue with your vehicle’s crankshaft position sensor. This component manages ignition timing and fuel injection. Thus, addressing the problem is important to avoid performance issues or damage. Many vehicles can undergo an inexpensive repair to replace the crankshaft position sensor. A qualified mechanic can do this. But it’s best to have the vehicle diagnosed. This will determine the exact cause of the PO335 code in your specific situation. By doing preventative maintenance and monitoring, you may avoid P0335 errors. This will ensure your vehicle continues to operate.

To diagnose and repair code PO335, a certified mechanic should:

1. Inspect and test the crankshaft position sensor to determine if it needs replacement.
2. Replace the crankshaft position sensor if it is found to be malfunctioning. This may require the removal of other engine components to access the sensor.
3. After replacing the sensor, clear all diagnostic codes from the vehicle’s computer.
4. Road-test the vehicle to ensure the new crankshaft position sensor is working. Resume normal operation after the test.

To avoid future code PO335, test the crankshaft position sensor during routine maintenance. Driving with a malfunctioning sensor can cause permanent engine damage if left unaddressed.

Will bad spark plugs cause a P0335 code?

Faulty or failing spark plugs can trigger a PO335 diagnostic trouble code (DTC) for your vehicle. The PO335 code indicates that the crankshaft position sensor circuit is malfunctioning. This sensor
monitors the position and rotational speed of the crankshaft. It controls ignition timing and other engine functions.

Worn-out or damaged spark plugs disrupt the engine’s firing sequence and combustion. The crankshaft position sensor detects this disruption. This can prompt the P0335 DTC to turn on your vehicle’s check engine light. To remedy this issue, you should replace the spark plugs and clear the code. New, gapped spark plugs will restore the engine’s optimal performance. They will also turn off the warning light.

Preventing future PO335 codes involves inspecting and replacing your spark plugs. As a general rule, most vehicles need new spark plugs every 30,000 to 100,000 miles, depending on the make and model. Replacing them at the recommended interval will maximise engine power and efficiency. It will also cut the risk of misfire-related DTCs like P0335. Proper vehicle maintenance and care will help keep your check engine light off. It will also ensure many miles of trouble-free driving.

What Does Code PO335 Mean?

Error code P0335 indicates a problem with the crankshaft position sensor on your vehicle. The crankshaft position sensor monitors the position and rotational speed of the crankshaft. It sends this data to the vehicle’s engine control unit (ECU). The ECU uses this information to determine the engine’s proper ignition timing and fuel injection.

The code PO335 triggers when the crankshaft position sensor malfunctions or completely fails. This often causes the check engine light to turn on. The vehicle may experience problems like rough idling, misfiring, stalling, or difficulty starting. To diagnose code PO335, use a scanner to check for stored diagnostic trouble codes (DTCs) and live data. Test the crankshaft position sensor’s input and output signals.

The most common solution for PO335 is to replace the faulty crankshaft position sensor. The engine block mounts the sensor near the crank pulley. To replace the sensor, first disconnect it from the engine wiring harness. Then, unscrew the sensor from its mount. Next, install a new sensor. Reconnect the wiring. Then, clear any DTCs with a scanner to reset the check engine light. To prevent future PO335 codes, use high-quality replacement parts. Keep the sensor clean and mounted. Also, address any other engine issues that could damage the new sensor.

What is a pending fault? (PO335)

A pending fault means your vehicle’s onboard diagnostic system has detected an issue. But it has not yet reached the threshold to trigger the check engine light. The P0335 code refers to a problem with your crankshaft position sensor. This sensor monitors the position and rotational speed of your crankshaft. It helps control functions like fuel injection and ignition timing.

When the ECU stores a pending fault code, it means the sensor readings have started to fluctuate or go out of their normal range. The ECU will continue to check the sensor. It will determine if the issue is ongoing before illuminating the check engine light. Often, pending codes will clear on their own if the problem is temporary. But if the code persists or your check engine light comes on, it indicates you likely have a failing crankshaft position sensor. You should replace it.

To diagnose and reset a P0335 pending fault, use an OBD2 scanner. Connect the scanner to your vehicle’s diagnostic port. The scanner can pull the pending code from your ECU to identify the issue. You should then test the crankshaft position sensor with a digital multimeter. Check for proper resistance to it. If the sensor is out of range, you need to replace it. Resetting the ECU after replacement may clear the pending code. It may also turn off the check engine light. If the light remains on, you may need to have it diagnosed by a certified mechanic to check for any more faults.

 

FAQ:Frequently Asked Questions

1. Where is the crankshaft position sensor located?

You can find the sensor near the crankshaft pulley, engine block, or timing cover. Check your vehicle’s service manual for the exact location.
