Cooling Fan Speed Sensor

Replace the harness with an improved design part no.

Cooling fan speed sensor.

Cooling fan speed sensor circuit. If the fan comes on you may have a bad temperature sensor or gauge. This diagnostic trouble code dtc is a generic obd ii powertrain code. 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. 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. What the p0526 code means. The damage occurs because the harness pulls out of its plastic protective sleeve exposing the insulation to the sharp edges of the sleeve.

The p0526 cooling fan speed sensor circuit problem appears because of damaged wires in the cooling fan harness. 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. If the cooling fan speed sensor fails then it must be replaced. If during operation the pcm detects a loss of the cooling fan speed signal dtc p0526 will set.

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.
