1 vehicles · 1 makes · $900-$3,000 repair
Most Reported On
P1746 is an OBD-II diagnostic trouble code meaning “Electronic Pressure Control (EPC) Solenoid — Open Circuit / Low Conditions.” This is a manufacturer-specific powertrain code and the meaning depends on the brand. On Ford (and Mazda vehicles using Ford transmissions) it means the powertrain control module commanded the electronic pressure control solenoid but saw an open/low condition in that circuit — the solenoid that regulates transmission line pressure is not responding correctly, which shows up as harsh or erratic shifts, slipping, or limp mode with maximum line pressure. On Volkswagen/Audi the same number (VAG 00532) is a transmission control module relay supply voltage (B+) malfunction, often from low battery voltage or a bad ground, so confirm which definition applies to your vehicle. This code is most commonly reported on 1997-2001 Ford Explorer (XL, XLS, XLT, Eddie Bauer, Limited, Sport), with repair costs ranging from $900 to $3,000.
