P2558 - OBD Trouble Code

<<See All OBD Codes

Confused? Too many big words to comprehend? Only for you Parts Avatar has written down here all that is important to know about the error code P2558. This OBD-II P2558 code strictly focuses on OBD-II vehicles (1996-newer). The list includes brands ranging from Audi, Ford, BMW, Lincoln, Chrysler, etc. (but is not limited to). Though this code is general in nature, the repair steps can be differentiated on the basis of year, make, model and powertrain configuration. This code shares similarities with other OBD codes namely: P2556, P2557 and P2559. All these codes are related to engine coolant level sensor or switch circuit. Numerous vehicles have pre installed coolant level sensor or switch. These function employing certain kind of a float (similar to one used by the gas gauge sending unit). Whenever the coolant level drops below the specified level, this completes the circuit and updates the powertrain control module to set the code

When the powertrain control module identifies a voltage or resistance inside the engine coolant level sensor/switch circuit that is extremely low (below the specified range), the code P2558 is stored followed by an illuminated check engine or low coolant/overheating light.

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

• A defective engine coolant level sensor/switch
• Open or short circuits in the engine coolant level sensor/switch harness
• A deficient electrical connection in the engine coolant level sensor/switch circuit

Radiator - The Internal Combustion Engines Are Cooled By Circulating A Liquid Called Engine Coolant Through The Engine Block, Where It Is Heated, Then Through A Radiator Where It Loses Heat To The Atmosphere, And Then Returned Back To The Engine. It Is Recommended To Change Or Mend It As Soon As Possible.
10. Engine Temperature Sensor - Seeing The Error Code P2556? Well, It Could Be Triggered Due To A Fault In The Engine Temperature Sensor. Apart From This One Is Likely To Notice A Whole Lot Of Problems With The Engine Too. Repair Or Replace Now!

We at Parts Avatar Canada care for our customers, and that’s why we will help you to diagnose P2558 code by listing out some major symptoms. They are mentioned below as follows:

Common Symptoms

• Possibly an overheating engine (when the coolant level is less than the required)
• Illuminated malfunction indicator light (along with a stored code)

Have a look at some ways with which you can correct the P2558 code:

• Repair or replace a defective engine coolant level sensor/switch as per the requirements
• Amendments should be performed to fix a weak electrical connection running in the engine coolant level sensor/switch circuit
• All the open or short circuits in the engine coolant level sensor/switch harness should be mended or restored instantly

We are sure that now all your issues would be resolved.

Here are some steps which you should follow in order to diagnose this fault code:

First and foremost, the troubleshooting process for any damage is to explore the technical service bulletins (TSB's) for that particular vehicle by year, model and engine/transmission configuration. It is advised to do so as it helps save a lot of money and time while the procedure is being performed. Next, situate all the electrical parts linked to the engine coolant level circuit. Visually inspect these for possible signs of damage. Most probably, you can find this sensor at the following place: the coolant reservoir or overflow bottle, or the radiator. It is advised for you to refer to the vehicle specific repair manual in order to determine the location in your vehicle.

Next, a thorough visual inspection should be performed to check the linked wiring for usual defects such as scratching, rubbing, loose wires, or burn spots. Check the connectors and circuitry for security, corrosion and damaged pins. This inspection should include all the wiring connectors and circuitry linked to all components including the PCM. Well, the specific tech data for the vehicle should constantly be referred to, to verify the configuration of the oil level safety circuit and ensure if all the fuses or fuse-able links are integrated into the circuit.

Advance steps that should be performed:

It should be noted that the advance steps that are performed are specific to the vehicle and require the correct equipment. A digital multimeter and specific technical references for the vehicle will be required to perform the procedure accurately. The oil pressure gauge facilitates the troubleshooting process in such situations.

Common Mistakes When Diagnosing the P2558 Code

Here we have listed a few common mistakes that should be avoided while diagnosing the error code P2558:

Often, the mechanics make this common mistake of avoiding minor repairs while concentrating majorly on other repairs. It is advised to not overlook the minor repairs as sometimes the error code can be solved by just simply making a few slight changes. This helps a lot in saving both time and money. Also, the codes should be treated in the order they are stored.
