Order of inspection
P0527 Fan Speed Sensor Circuit Range/Performance Medium
The P0527 code means the fan speed sensor gives a reading that is electrically valid but does not match what the computer expects. The main effect is imprecise fan control. The sensor, the connector and the wiring fail about equally often, so test before you buy parts.
