Cooling Fan Speed Sensor

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.

Cooling fan speed sensor. 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. 89024920 and tape the wires to prevent. What the p0526 code means. If the cooling fan speed sensor fails then it must be replaced.

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. Cooling fan speed sensor circuit. 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. 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. The damage occurs because the harness pulls out of its plastic protective sleeve exposing the insulation to the sharp edges of the sleeve. Replace the harness with an improved design part no. 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.
