What's odd is that the engine compartment fan works and will remain running while te vehicle is off to cool the engine bay.
Leading evidence: 'Run while te vehicle is off' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Run while te vehicle is off' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 02 996 gets an engine compartment fan warning when it's hotter outside and I've driven the car for more than 20 minutes. This causes the light on the water temperature gauge to flash red on and off. Water temps remain normal. What's odd is that the engine compartment fan works and will remain running while te vehicle is off to cool the engine bay.
Does anyone one know why I keep getting this warning ?
Thanks for for the help
Did the warning msg say the engine compartment fan? Check the engine compartment temp sensor sitting between the intake manifold between cyl #4&5. It may have been knocked off of its position.
I'm with Ahsai on this one. What I find strange is you are in Alberta and your engine compartment fan is running. I live in Florida and I can count on one hand the number of times my engine compartment fan has come on. Rarely happens. But it will happen if the sensor pops out of the grommet and is sitting on the engine.
From Slakker:
Four functions of the coolant warning light:
1. Engine coolant level too low
— light flashes slowly (0.5 Hz)
2. Engine compartment temperature too high
— light flashes slowly (0.5 Hz) (engine compartment blower might be faulty)
3. Engine coolant temperature too high
— light is lit; pointer on the right
4. Temperature sensor at water outlet faulty
— light flashes rapidly (1 Hz); pointer on the right
Note
The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously
(1Hz = 1 flash per second. 0.5Hz = 2 seconds per flash)
So it might be the temperature sensor is faulty (if the light is rapid flashing).
Mine runs quite often. When I am at full temp it cycles on/off all the time. My sensor is correctly mounted. I wonder if on the 996.2 the fan runs more often....quite frankly as hot as it gets in there I'm always glad to hear it running.
I'm in N Cal where today's hi will be 106F and mine runs frequently. Even in the winter when I get off the freeway it will come on for a few seconds. 2002C2
I'm having this exact same issue coinciding with a recent heat wave in wisconsin. Everything is working perfectly but I am getting the warning light and the blinking red light to the right of the coolant temperature gauge. This isn't a constant occurrence, only intermittently when the weather has been unusually warm. Also getting a "failure indicator" warning with an oil can symbol from time to time, but again, temp and oil pressure is all perfect. i'll chalk that up to needing a new sensor. Anyone else experience these issues? How did you address them?
Reviving a thread to hopefully get last years questions answered. Got my 05 C4S out of storage last week and have driven it a few times for extended periods in various spring temps. Highest temp today was mid to low 70s and again got the Engine Compartment Fan Failure warning with a blinking red on the temp gauge. Only came on for a few seconds then disappeared. But then came home and the parked and the engine compartment fan came on for 10-15 minutes. I only drove approximately 7-8 miles with no spirited driving at all. Temp gauge remained perfect, just beyond 180. Sensor issue? Anyone have a pic as to where this engine compartment fan sensor is located?
