Code P2559 Description
The P2559 code indicates that there is a high voltage condition in the engine coolant level sensor/switch circuit. This sensor is responsible for monitoring the coolant level in the vehicle's cooling system. When the sensor detects that the coolant level is too low, it sends a signal to the engine control module (ECM) to alert the driver.
Common Causes of P2559
- Faulty engine coolant level sensor/switch
- Wiring issues in the coolant level sensor circuit
- Corrosion or poor connections in the sensor circuit
- Low coolant level in the cooling system
- ECM software or hardware issues
Symptoms of P2559
- Check engine light illuminated on the dashboard
- Inaccurate coolant level readings on the dashboard
- Engine overheating
- Loss of coolant without visible leaks
- Poor engine performance
How to Fix P2559
- Begin by checking the coolant level in the cooling system and ensuring it is at the proper level.
- Inspect the wiring and connections in the coolant level sensor circuit for any damage or corrosion. Repair or replace as needed.
- Test the engine coolant level sensor/switch for proper functionality. Replace if found to be faulty.
- Clear the diagnostic trouble codes from the ECM and perform a test drive to ensure the issue has been resolved.
- If the problem persists, further diagnostic testing may be required to identify any underlying issues with the ECM or other components.
Cost to Fix P2559
The typical repair costs for addressing a P2559 code can range from $100 to $300, depending on the specific cause of the issue and the cost of replacement parts. However, it's important to note that labor rates can vary significantly, so it's advisable to check with local auto repair shops for a more accurate estimate based on your location and vehicle type.

Frequently Asked Questions about P2559 Code
What does the OBDII code P2559 mean?
P2559 indicates a high voltage issue in the Engine Coolant Level Sensor/Switch Circuit, suggesting a potential problem with the sensor or its associated wiring.
What are common symptoms of the P2559 code?
Symptoms may include the check engine light turning on, inaccurate coolant level readings, or overheating if the coolant is actually low.
What causes the P2559 code to appear?
Common causes include a faulty engine coolant level sensor, damaged or corroded wiring/connectors, or a malfunction in the vehicle’s PCM (Powertrain Control Module).
Can I drive my car with the P2559 code?
While it’s possible to drive, it’s not recommended as it may lead to engine overheating if the coolant level is truly low or if the sensor issue isn’t addressed.
How do I diagnose the P2559 code?
Diagnosis involves inspecting the sensor, checking for damaged wiring or connectors, and testing the circuit voltage with a multimeter to confirm the high voltage condition.
How can I fix the P2559 code?
Repairs may include replacing the coolant level sensor, repairing damaged wiring or connectors, or updating/reprogramming the PCM if necessary.
How much does it cost to fix the P2559 code?
Costs vary depending on the issue, but replacing a coolant level sensor typically costs $50–$150 for parts and labor combined.
Can a dirty coolant reservoir trigger the P2559 code?
Yes, a dirty or contaminated coolant reservoir can interfere with the sensor’s performance, potentially triggering the code.
Will clearing the P2559 code solve the problem?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be addressed to prevent the code from returning.
Is the P2559 code related to low coolant levels?
Not directly. The code indicates a sensor circuit issue, but it’s important to verify that the coolant level is adequate to avoid engine damage.
