P0777 Code - Pressure Control Solenoid 'B' Stuck On

What does P0777 Mean?

The Pressure Control (PC) Solenoid Valve an electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As current flow is increased, the magnetic field produced by the coil moves the solenoid’s plunger further away from the exhaust port. Opening the exhaust port decreases the output fluid pressure regulated by the PC solenoid valve, which ultimately decreases line pressure. The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).

What are the common causes of P0777 ?

• Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.
• Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)
• Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.

How do you troubleshoot P0777 ?

To repair a P0777 trouble code, the mechanic should perform the following steps:

• Repair any leaks detected.
• If the transmission has been damaged due to a low fluid condition, repair or rebuild the transmission, followed by a fluid flush and replacement. Then install a new torque converter before proceeding.
• Replace any burnt or otherwise damaged wiring, connectors, or components.
• Repair or replace the hydraulic pump. Replacement of the pump requires the mechanic to remove the transmission and partially disassemble it.
• Replace any damaged or shorted system circuits or connectors.
• Replace the electronic pressure control solenoid if faulty.
• Replace the PCM if found to be at fault.
