What is a pressure control solenoid B?

In order to shift gears, the ECU has to control the fluid pressure inside the transmission, using small plunger devices called pressure control solenoids. If a mechanical fault has been detected with the solenoid using the ‘B’ designation, a P0776 diagnostic trouble code will be stored.

What is pressure control solenoid B performance or stuck off?

Error Code P0776 is defined as Pressure Control Solenoid B Performance or Stuck Off, a problem usually caused by dirty transmission fluid or faulty parts. This code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system, or vehicles made since 1996 up to present.

How do I fix code po775?

The most common repairs to address the P0775 are as follows:

  1. Repair or replace damaged wiring harness.
  2. Repair or replace damaged or corroded circuitry.
  3. Rebuild or replace transmission.
  4. Replace or add transmission fluid.
  5. Repair or replace high pressure pump.
  6. Repair or replace electronic pressure control solenoid.

What causes a pressure solenoid to malfunction in a Ford?

P0775 FORD Possible Causes 1 Low transmission fluid level 2 Dirty transmission fluid 3 Faulty line pressure solenoid ‘B’ valve 4 Line pressure solenoid ‘B’ valve harness is open or shorted 5 Line pressure solenoid ‘B’ valve circuit poor electrical connection

What is the trouble code for a Solenoid B?

Most automatic transmissions incorporate at least three solenoids that are solenoid A, B and C. The trouble codes related to the “B” solenoid are codes P0775, P0776, P0777, P0778 and P0779. The code set is based on the specific malfunction that alerts the PCM and illuminates the Check Engine Light.

What is the code on my Ford Explorer?

I have a 2003 Ford Explorer, v6 with 102,000 miles. The Overdrive light and check engine light came on and set code P0775. I can’t find any info on that code.

How does the solenoid valve on an oil pump work?

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).
