P0493 Kodu Nedir?
Belirti: Two kinds of cooling fan carry these codes: electric fans switched by relays or driven by a PWM/LIN fan module with speed feedback, and engine-driven fans with an electronically controlled viscous clutch, whose speed a Hall sensor reports – GM calls them EV fans, meaning electro-viscous, not electric vehicle.
Two kinds of cooling fan carry these codes: electric fans switched by relays or driven by a PWM/LIN fan module with speed feedback, and engine-driven fans with an electronically controlled viscous clutch, whose speed a Hall sensor reports – GM calls them EV fans, meaning electro-viscous, not electric vehicle. P0493 is documented only on GM petrol engines of 2004–06 with a viscous fan: the measured fan speed exceeds a limit that is hardly physically possible (about 6400 rpm), so it is effectively a plausibility check of the speed signal or a seized clutch at high engine speed. Two counts set it, with the warning lamp on the first trip – unlike P0495, which needs two trips. Ford, FCA and GM from 2014 were not found to use it.
P0493 Kodunun Yaygın Nedenleri
- Viscous clutch seized – fan runs rigidly with the belt drive
- Interference or faulty signal from the fan speed sensor
- Clutch solenoid or its control stuck at fully engaged
- Engine module or software
