P1474 MERCURY - Low Fan Control Primary Circuit
P1474 MERCURY Possible Causes
- Faulty Cooling Fan
- Faulty Cooling Fan Relay
- Cooling Fan harness is open or shorted
- Cooling Fan circuit poor electrical connection
How is the P1474 MERCURY code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
What is the cost to diagnose the P1474 MERCURY code
Labor: 1.0The cost to diagnose the P1474 MERCURY code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?Cooling fan enabled Engine Control Module (ECM) detected excessive current draw or no voltage at all
- Engine Light ON (or Service Engine Soon Warning Light)
P1474 MERCURY MeaningMonitors the Low Fan Control (LFC) primary circuit output from the Powertrain Control Module (PCM). The test fails if the PCM grounds the LFC circuit, excessive current draw is detected on the LFC circuit, or with the LFC circuit not grounded by the PCM, voltage is not detected on the LFC circuit (the PCM expects to detect VPWR voltage coming through the low speed FC relay coil to the LFC circuit).
