Electronic Pressure Control Solenoid

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2002 Mercury Grand Marquis, 2002 Lincoln Town Car, 2002 Ford Crown Victoria, 2001 Mercury Mountaineer, and 2001 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

The Electronic Pressure Control (EPC) solenoid receives signal from the PCM to control line pressure and 2-3 backout valve function. If EPC solenoid fails in ON position, transmission is operated in fail-safe mode. Minimum line pressure is present. If EPC solenoid fails in OFF position, line pressure is at maximum pressure. Harsh engagements and shifts will result.
