What Does the P0526 Code Mean?

The Engine Control Module (ECM) uses the cooling fan speed signal in order to determine the actual fan speed in relation to the desired fan speed. The ECM uses the cooling fan speed signal in order to reduce the cooling fan noise and maintain the powertrain cooling requirements. The ECM supplies a 5-volt reference and low reference circuit to the clutch hall effect sensor in the cooling fan clutch. The hall effect sensor returns a signal pulse through the signal circuit in response to the reluctor track, which is located inside the fan clutch. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the cooling fan speed signal is greater or less than a predetermined threshold.
