What is the P0527 fault code? What does it signify?
A P0527 code is an indication of a problem in the cooling fan speed sensor circuit.
Cooling fans are used by the powertrain controller module (PCM), to cool the engine and cooling the air conditioning system. Fans with fan thermal and electronic control are equipped with fan speed sensors. These sensors can be used to verify that the fan is operating and to monitor fan speed while it is running. This sensor is typically a 3-wire hall effect sensor. A 5 volt reference is provided by the PCM. This wire acts as a ground wire and a signal wire. It determines the fan speed. This sensor is used to check if the fan speed you desire matches the current speed.
If the PCM detects the fan speed desired is not matching the voltage signal from its sensor and the fan is not functioning as expected, it will set a P0527 Code.
P0527 fault codes are found in vehicles of various makes and models, including those made by Peugeot, Nissan, Isuzu Fords, Chevrolets, Land Rovers, Duramax and BMW.
What is the P0527 Fault Code and Why Does It Happen?
These are the most common reasons that P0527 is triggered
- – Defective cooling fan speed sensor
- – Defective engine coolant temperature (ECT) sensor
- – Corroded, damaged, or burnt wires to cooling fan sensors (ECT sensor, fanspeed sensor), loose connectors, or open or short circuit issues
- – Cooling fan fuse blown
- – Defective cooling fan relay
- – Remove or replace the “V” belt
- – Broken or defective fan thermal or electric
What are the symptoms of P0527 malfunction code?
You may experience the following symptoms if your vehicle has the code P0527:
- – Illumination for the check engine light
- – Engine overheating
- – Inefficient operation
How do I fix the P0527 fault code?
When diagnosing code P0527, the most common mistake is to replace critical components without fully inspecting the entire system. The first thing to do is inspect the fuses, relays, cables, and connectors. After each intervention, clear the codes and retest the vehicle.
There are several repairs that can resolve the P0527 fault code.
- – Replacing blownfuses
- Relay cooling fan failure
- – Replacing damaged or burned out connectors and cables causing short circuit
- – Repair and replacement of worn or damaged electrical components
- – Replace the damaged cooling fan speed sensor
- Replacing an engine coolant temperature sensor that is defective
- Replacing a thermal fan that is not working
- – Replacing the fan motor that is defective
- – Replacing an old or worn V-belt
- – Repair the damaged cooling fan
How serious is the P0527 fault code?
The code P0527 is a serious problem and must be fixed immediately. This code will cause the engine to heat up and eventually become unusable. For diagnosis and repair, the vehicle should be taken immediately to a mechanic.
