Error Code P1747 – Symptoms, Causes and Solutions

He error code P1747 It is defined as a Transmission Pressure Control Short Circuit. It refers to a problem in the operation of the circuit EPC (electronic pressure control) and in the operation of the EPC sensor.

 

This error code is a manufacturer-specific trouble code, meaning it does not apply to all makes of vehicles. Rather, it applies only to specific brands of vehicles, such as Dodge, Ford, etc The specification of the definition, the troubleshooting, and the repairs still vary from one make and model to another.

Definition

The transmission solenoid fault code belongs to the EPC circuit. If this circuit fails, the vehicle will enter ‘Limp Mode’ or hard shifting.

Clean Mode is a safety system designed to protect the engine from being damaged during extremely high temperatures. When this mode is activated, the engine will run only at RPM very slow and you will barely be able to move.

Common symptoms

Like other error codes, this code activates the light Check Engine and registers the code in the vehicle system. Other symptoms include

  • Abrupt changes
  • Hesitation
  • Jam

Possible causes

  • Shorted wiring on EPC solenoid

What does transmission solenoid fault code p1747 mean?

Rather, it applies only to specific brands of vehicles, such as Dodge, Ford, etc. Definition specification, troubleshooting, and repairs still vary from one make and model to another.

The transmission solenoid fault code belongs to the EPC circuit. If this circuit fails, the vehicle will go into ‘Limp Mode’ or abrupt gear change.

How to know if your car has a P1747 code?

Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed, or corroded connector pins.

The cost of diagnosing code P1747 is 1.0 hours of work. Auto repair labor prices vary widely across the country, and even within the same city.

What is the EPC sensor error code?

He error code P1747 is defined as a Transmission Pressure Control Short Circuit. It refers to a problem in the operation of the EPC (electronic pressure control) circuit and in the operation of the EPC sensor.

Specifications on setting up, troubleshooting, and repairs continue to vary from one make and model to another. The transmission solenoid fault code belongs to the EPC circuit. If this circuit fails, the vehicle will go into “Clean Mode” or sudden changes.

What does DTC mean on Ford p1747?

P1747 FORD Description Diagnostic Trouble Code (DTC) will be established if with the engine running at cruising speed, the Powertrain Control Module (PCM) detects that the Torque Converter Clutch (TCC) circuit was shorted.

How to check it

To check this code, check the code after restarting it. Use a Digital Voltmeter (DVOM) and check the voltage going to the EPC solenoid.

Be sure to use the wiring diagram provided by the ATS to locate the EPC cables. After the test, check to see if the codes are working or receiving the proper voltage signal from the engine computer.

How to fix

The easiest and most direct way to fix this problem is to replace the sensor EPC. When replacing the sensor, make sure the wires connected to it are not shorted. Check for signs of broken wires that could cause inadequate insulation as well as poor routing.

In many cases, a shorted or broken wire is enough to cause the EPC solenoid to fail.

Also, during testing, make sure the tray gets hot enough, as most shorted wires will only come out after the vehicle is running for some time, causing an intermittent flashing of the error code.

Also, be sure to check the integrity of the cables by tracing from the transmission to the right module using the wiring diagram. Anyone who is into DIY can check and repair this code as long as you have the wiring diagram to do it.
