Common Symptoms For Kia Potentia P0A77

  1. The PCM calculates input data and regulates transmission fluid pressure via a specially designed pressure control solenoid. The automatic transmission uses a high pressure pump (driven by the engine via the torque converter) to circulate fluid through the transmission hydraulic circuits in the transmission housing and valve body
  2. Begin your diagnosis with a visual inspection of system wiring, connectors, and components
  3. The PCM will read the sensor resistance and pass it
  4. If the transmission functions normally and the code doesn't return, then it was likely caused by transmission slippage due to a low fluid level/pressure condition. If the code returns and the transmission slips or suffers from delayed engagement, check pump pressure using a manual pressure gauge

Kia Potentia P0A77 Troubleshooting

When you put your foot down on the brakes you expect your car to quietly slow down and come to a stop. The power your foot applies on the brake pedal is assisted by hydraulic pressure. Your foot's force engages a piston and caliper with brake pads attached (bonded abrasive and heat resistance metal or ceramic) to put pressure on the rotor. Kia Potentia P0A77 OBD2 specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set.
