P079C OBD-II: Transmission Friction Element "C" Slip Detected
P079C Severity
Should you fix P079C yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P079C?
The Hybrid Control Module monitors the transmission clutches for slippage. If the Control Module detects any slippage when the third clutch is activated code P079C will be set. The hybrid control module may also place the vehicle in "limp home", limiting available engine/transmission performance to prevent additional damage.
