<<See All OBD Codes

Don’t know a thing about the error code P2557? Don’t worry, only for our customers we have gathered here all the information that you need to know about the error code P2557. This OBD-II trouble code is associated to other codes namely: P2556, P2558 and P2559. All these codes are related to the engine coolant level sensor and/or switch/ circuit. Numerous vehicles have this engine coolant sensor/switch installed. These function typically by utilizing some kind of a float that shares similarities with the one used by the gas gauge sending unit. Whensoever the coolant level falls below the certain specified level, this completes the circuit and updates the PCM to set the error code P2557.

The role of controlling the engine coolant level sensor/switch signals is undertaken by the engine control module (ECM). Also, it should be noted that powertrain control module stores the error code P2557 whenever the signal in the engine coolant level sensor/switch falls out of the manufacturer’s specifications.

What causes this problem with Engine Coolant Level Sensor/Switch Circuit Range/Performance?

• A malfunctioning engine coolant level sensor/switch
• Disconnected or short circuited engine coolant level sensor/switch harness
• A weak electrical connection in the engine coolant level sensor/switch circuit

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2557 code by mentioning some major symptoms below:

Common Symptoms

• The engine overheating (when the coolant level is deficient)
• A stored trouble code along with the MIL lamp flashing

Have a look at some ways with which you can correct the P2557 code:

• Repair or replace your faulty engine coolant level sensor/switch
• Make sure you repair or restore all the disconnected or shorted harnesses in the engine coolant level sensor/switch
• Immediately restore a weak electrical connection running in the engine coolant level sensor/switch circuit

There is no need to get strained if your OBD code is still flashing up as we are here at your service. Have a look at our superior variety of ECM, PCM, engine coolant level sensor, engine coolant system, cooling system, thermostat, water pump, coolant hoses, cooling fan, radiator, engine temperature sensor and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

Firstly we advise you to search for any disconnected ground straps or a tainted ground where the fuel tank is grounded to the frame. All the wiring harness connectors should be checked for signs of physical damage. Next, employ the DVOM to probe the resistance and the continuity on all the system circuits if the actuator and sensor resistance levels comply with the factory’ provisions. In case the engine displays a miss and there isn’t a code, explore to find out the cylinder that has been misfiring. Also, we advise you to sprinkle water on each cylinder exhaust port, if the exhaust manifold is visible. One can observe that the water sprinkled will evaporate immediately on good cylinders and slowly on the missing cylinder. If this entire procedure fails, next you should pull the plugs out and check the condition. 

Common Mistakes When Diagnosing The P2557 Code

One of the most common mistakes committed by the technician is overlooking of the minor repairs while performing the replacements of major parts. This can lead to a misdiagnoses. Also, the codes should be cleared in the order they have been stored.
