P0528 Code: Fan Speed Sensor Circuit No Signal

Vehicle radiators are equipped with a cooling fan that blows cool air, allowing the radiator to dissipate heat faster. If the P0528 code has been stored, this article will inform you about the code’s definition and common causes and symptoms.

What Does the P0528 Code Mean? 

The powertrain control module is responsible for controlling the cooling fan’s speed. The cooling fan provides more cooling in situations like hot days, or when the vehicle is being driven in stop-and-go traffic where there isn’t sufficient airflow to cool the radiator. If the powertrain control module (PCM) can’t control the cooling fan, it will trigger the P0528 code. 

Getting air to flow through the radiators is important. Otherwise, the engine can overheat and lead to engine damage, which will require expensive repairs. 

Note: The definition of the P0528 code can be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition. 

What are the Common Causes of the P0528 Code?

The issues that trigger the P0528 code are commonly caused by the following issues: 

• Failed cooling fan
• Faulty electric fan clutch
• Faulty wiring
• Bad cooling fan relay or blown fuse 
• PCM failure

What are the Common Symptoms of the P0528 Code? 

The problems that set a P0528 code can cause your vehicle to show the following symptoms: 

• Illuminated check engine light
• Overheating engine
• The engine runs hotter than normal

How to Diagnose the P0528 Code

The P0528 code might be a generic powertrain code that has a list of common causes, but you should still verify if your vehicle has those issues before you make repairs.

Diagnosing diagnostic trouble codes (DTCs) typically involves inspecting and testing the concerned components. Diagnosing the P0528 code might require some technical knowledge because you might need to inspect the cooling fan. Accessing and identifying the right components might also be difficult. If you don’t think you’re up to the task, then you shouldn’t hesitate to leave the task to a professional mechanic. Otherwise, you can diagnose the problem yourself.

How to Fix the P0528 Code 

There isn’t a single solution that can fix the issues that cause a DTC because repair procedures can vary greatly between different makes and models. Letting a trusted mechanic do the job is probably the best course of action. However, if you think your automotive know-how is good enough to do the fix yourself, it’s best to follow the right steps and proper protocols to avoid any further issues down the line. Also, make sure you find the root cause first before proceeding with the repair process. 

After finding the problem, you can look at reputable internet repair resources and how-to guides like those from Chilton. You might also want to check out an ALLDATA vehicle subscription to find vehicle-specific repair information.
