What does Hyundai P0335 Code Mean?
The Hyundai P0335 code refers to a malfunction in the crankshaft position sensor circuit. The crankshaft position sensor is responsible for monitoring the position and rotational speed of the crankshaft in the engine. The information provided by this sensor is used by the engine control module (ECM) to control ignition spark and fuel injector timing.
When the ECM detects a malfunction in the crankshaft position sensor circuit, it will set the P0335 code and turn on the check engine light. This code can indicate a problem with the sensor itself or with the circuit wiring or connectors. It is one of the most common Hyundai P0335 codes.
Hyundai P0335 Code Repair Cost
The cost of diagnosing the P0335 Hyundai code is 1.0 hour of labor, with the typical auto repair shop charging between $75 and $150 per hour for labor. However, the total cost of repairs may vary based on the specific cause of the issue and any required parts or additional labor.
How to Diagnose and Repair Hyundai P0335 Code step by step
Here are the steps to diagnose and repair a Hyundai P0335 code:
#Step 1 – Check the crankshaft position sensor: The first step is to check the crankshaft position sensor, which is responsible for providing information about the crankshaft’s position and speed to the engine control module (ECM). A faulty sensor can trigger the P0335 code. Check the sensor’s wiring and connectors for any damage or corrosion. If necessary, replace the sensor.
#Step 2 – Inspect the reluctor wheel: The reluctor wheel is a component on the crankshaft that the sensor uses to determine the crankshaft’s position and speed. Inspect the wheel for any damage or misalignment that could be causing the code.
#Step 3 – Check the wiring and connectors: Inspect the wiring and connectors that lead to the crankshaft position sensor. Look for any damage or corrosion that could be causing a poor electrical connection.
#Step 4 – Inspect the engine control module: If the above steps do not resolve the issue, it’s possible that the engine control module (ECM) is at fault. Check the ECM for any signs of damage or corrosion. If necessary, replace the ECM.
#Step 5 – Clear the code: Once the repair has been made, clear the code using a code scanner. Start the engine and check if the code has returned. If it has not, the issue has been resolved.
Can I drive Hyundai with P0335 Code?
It is not recommended to drive your Hyundai with the P0335 code as it can cause damage to the engine and affect its performance. It is recommended to have the issue diagnosed and repaired as soon as possible.
Possible Causes of the Hyundai P0335 Code
The possible causes of the Hyundai P0335 code are:
- Faulty crankshaft position sensor
- Damaged or corroded crankshaft position sensor wiring
- Crankshaft position sensor circuit poor electrical connection
- Faulty starter motor
- Starting system circuit issues
- Dead or weak battery
- Faulty Engine Control Module (ECM) – rare
Hyundai P0335 Code Possible Symptoms
The Hyundai P0335 code is associated with the malfunction of the crankshaft position sensor. When this sensor fails or malfunctions, it can cause a range of symptoms that may include the following:
#Symptoms 1 – Engine Light ON (or Service Engine Soon Warning Light): The check engine light will illuminate on the dashboard, indicating that there is a problem with the engine. The light may come on and stay on, or it may flash, indicating a more serious problem that requires immediate attention.
#Symptoms 2 – Possible lack/loss of Power: A faulty crankshaft position sensor can cause the engine to lose power or not run as smoothly as it should. This is because the sensor provides vital information about the position and speed of the crankshaft to the engine control module (ECM), which uses this information to adjust the timing and fuel injection.
#Symptoms 3 – Engine may stall while driving: A malfunctioning crankshaft position sensor can also cause the engine to stall while driving. This can be a serious safety issue, especially if the engine stalls while the vehicle is in motion. In some cases, the engine may be able to be restarted after a short period of time, while in other cases, it may not start at all.
Tools Needed to Diagnose Hyundai P0335 Code
The tools needed to diagnose a Hyundai P0335 code may include:
OBD-II Scanner: This tool is used to read the fault codes stored in the vehicle’s computer system.
Digital Multimeter: This tool is used to measure electrical signals in the vehicle’s wiring and sensor circuits.
Oscilloscope: This tool is used to measure the frequency and amplitude of electronic signals in the vehicle’s electrical system.
Automotive stethoscope: This tool is used to detect abnormal noises coming from the engine or other mechanical components.
Timing Light: This tool is used to check the engine’s ignition timing.
Voltage Tester: This tool is used to check for power and ground in the vehicle’s electrical system.
Socket Set: This tool is used to remove and install various engine components during diagnostic and repair procedures.
Wiring Diagram: This tool is used to identify the color-coding of the wires, pin-outs, and connectors for the vehicle’s electrical system.
Hyundai P0335 code Common Diagnosis Mistakes
Common diagnosis mistakes for the Hyundai P0335 code include:
#Mistake 1 – Replacing the crankshaft position sensor without properly testing it first: The sensor may not be the problem, but rather a wiring issue or a problem with the engine’s computer.
#Mistake 2 – Not checking the wiring harness for damage: The wiring harness can become damaged from age, heat, or corrosion. It’s important to check the wiring before replacing any parts.
#Mistake 3 – Not checking the battery voltage: Low battery voltage can cause the sensor to malfunction and set the P0335 code.
#Mistake 4 – Not checking the reluctor wheel: The reluctor wheel can become damaged or dirty, causing the sensor to malfunction. It’s important to check the wheel before replacing the sensor.
#Mistake 5 – Focusing only on the sensor and not the engine as a whole: The P0335 code can be caused by a number of issues, not just a faulty sensor. It’s important to diagnose the entire engine system to determine the root cause of the problem.
