What is the diagnostic code for pressure control solenoid?

P0746 is a diagnostic trouble code (DTC) for “Pressure Control Solenoid Performance or Stuck Off”.

What does a transmission pressure control solenoid do?

► What Exactly Does a Pressure control Solenoid do? The transmission pressure control solenoid controls the fluid pressure to the internal friction plate clutches or drum bands. A bad or failing transmission pressure control solenoid can cause slipping, which can result in the transmission overheating.

Are there any common issues with solenoid valves?

Another common issue is a too low differential pressure for indirect operated solenoid valves. These failure modes apply to all kinds of valves, such as 2 way valves, but also to 3 way valves .

What does it mean when a solenoid is stuck?

NOTE: In this definition, the words “stuck off”, refers to a condition in which the solenoid that controls the transmission fluid pressure is stuck in the “OFF”, or closed position. In this condition, the pressure of the transmission fluid cannot be controlled, directed, or regulated at all.

What are the symptoms of a bad pressure control solenoid?

Symptoms of a Faulty Transmission Pressure Control Solenoid. A problem with the transmission pressure control solenoid can cause the check engine light to illuminate with little to no other symptoms. On the other hand, it can cause transmission slipping in one or all gears.

Where is the electronic pressure control solenoid?

The electronic pressure control (EPC) solenoid is located on the main control valve body and is controlled by the PCM. The EPC controls line pressure used to apply and release clutches and bands in the transmission.

What are the signs of a bad transmission solenoid?

When the Low Reverse Shift Solenoid (also known as Shift Solenoid A), inside the transmission Solenoid Pack, goes bad, you’re gonna’ see two specific symptoms, these are: The check engine light (CEL) will be shining nice and bright on your instrument cluster.

How do you replace a solenoid?

Replace with a new solenoid if it is broken, nicked, corroded or otherwise damaged. Place a new solenoid in the socket and screw it in clockwise, being careful to tighten only it until it is secure. Do not overtighten or use a tool to try to get it tighter.
