What causes a P0480 code?
What causes a P0480 code?
P0480 means that the cooling fan 1 control circuit has a malfunction. The vehicles ECU has tried to control the cooling fan 1 and it has failed to operate or a fault was detected. The ECU then triggers a Check Engine Light to illuminate on the dashboard.
What is problem with p0526 cooling fan speed sensor code?
GM has issued a service bulletin to address a P0526 Cooling fan speed sensor circuit trouble code on the following vehicles: The P0526 Cooling fan speed sensor circuit problem appears because of damaged wires in the cooling fan harness.
What does the p0526 OBD-II trouble code mean?
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. 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 is the diagnostic code for fan speed sensor circuit?
P0526 is a diagnostic trouble code (DTC) for “Fan Speed Sensor Circuit”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does the cooling fan speed sensor do?
Some vehicles come with a special sensor called cooling fan speed sensor to detect movement during the operation of the vehicle.

Why does the PCM use the cooling fan speed signal?
The PCM uses the cooling fan speed signal in order to reduce the cooling fan noise and in order to maintain the powertrain cooling requirements. The PCM supplies power and ground to the clutch hall effect sensor of the cooling fan clutch.
