A cooling fan temperature switch or sensor in some vehicles can also get stuck which may cause the fan to run continuously any time you turn the ignition key on or start the engine.
Cooling fan speed sensor.
Cooling fan speed sensor circuit.
Thus it s good to monitor the fan speed using an advanced scan tool to verify if the actual fan speed matches the commanded fan speed.
89024920 and tape the wires to prevent.
In order to maintain proper powertrain cooling requirements and to reduce the cooling fan noise as it is in use the pcm uses a signal from the cooling fan to assess its speed.
The p0526 cooling fan speed sensor circuit problem appears because of damaged wires in the cooling fan harness.
If the cooling fan speed sensor fails then it must be replaced.
The p0526 code means that the pcm detected a voltage reading that was either too low or too high from the electric cooling fan control circuit.
The hall effect sensor returns a signal pulse through the speed signal circuit in response to the reluctor track which is located inside the fan clutch.
What the p0526 code means.
If the fan comes on you may have a bad temperature sensor or gauge.
If during operation the pcm detects a loss of the cooling fan speed signal dtc p0526 will set.
As the speed of the fan increases the voltage must also increase.
Replace the harness with an improved design part no.
