What is the p1651 fan 1 relay control circuit?
I have the same code. 2002 Grand Prix GTP 3.8L Supercharged. For your Pontiac, the P1651 code is for the Fan 1 Relay Control Circuit. Read more: http://engine-codes.com/p16… I found the fuse which is one of those big 30A fuses. It was blown hopefully once that’s replaced it’ll fix that error code and then I can figure out the P0140 code I get.
When to use diagnostic trouble code p1650 and p1651?
The Diagnostic Trouble Code (DTC) P1650 and P1651 will set if there is an open, short to ground or short to voltage on any of the QDM output circuits, faulty MIL circuit, faulty upshift light circuit, faulty cooling fan relay circuit or A/C relay circuit. Fault detected for 5 seconds will set P1651. Fault detected for 20 seconds will set P1650.
What happens when the relay on a cooling fan fails?
The engine may also run hot and overheat, too. The typical electric cooling fan circuit includes a temperature sensor, a relay, a control module and the fan motor. The relay is the component that fails most often; so be sure to test the relay as well as its power supply and ground connections.
Why are the cooling fans not working on my car?
Many other issues can cause the engine to run hot or overheat. Rather than uncommonly high engine temps, the driver may notice that the cooling fans have stopped running. A faulty or broken relay cannot deliver power to the cooling fans. In turn, the unpowered fans won’t run, leaving the radiator to its own devices.
