Cooling Fan Speed Sensor

This diagnostic trouble code dtc is a generic obd ii powertrain code.

Cooling fan speed sensor.

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. What the p0526 code means. 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.

Cooling fan speed sensor circuit. The damage occurs because the harness pulls out of its plastic protective sleeve exposing the insulation to the sharp edges of the sleeve. It is considered generic because it applies to all makes and models of vehicles 1996 newer although specific repair steps may vary depending on the model. If the fan comes on you may have a bad temperature sensor or gauge.

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. As the speed of the fan increases the voltage must also increase. Replace the harness with an improved design part no.

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.
