What does code P1747 mean?
Senior Member. P1747 EPC solenoid short circuit: It can be a short circuit in the wiring harness or the PCM shorted to ground. It can also be a faulty solenoid. Crawl under there and follow your transmission wiring harness to ensure you don’t have chaffing or a pinch in the wiring.
What does EPC solenoid do?
The EPC controls a pressure regulating spool valve and spring that holds or releases fluid pressure, typically back to the transmission’s sump. It’s a variable force solenoid that changes at around 32 Hz (32 times per second). It has more precise control than a conventional hydraulic pressure control system.
How do you test a EPC solenoid?
TESTING ON/OFF SOLENOIDS The testing of on/off solenoids is straightforward. Pressure should be applied to the inlet, and if it is normally closed, you should not see pressure at the outlet. Once energized, you should see pressure at the outlet. For a normally open solenoid, the opposite is true.
What are the symptoms of a bad EPC solenoid?
If you’re experiencing transmission solenoid troubles, it will become evident in one of four ways:
- Delayed gear shifting.
- You can’t downshift, and your engine continues to rev even when applying the brakes.
- Your transmission gets stuck in neutral.
- Shifting gears become rough and choppy.
What does transmission solenoid failure code p1747 mean?
Rather, it applies only to specific vehicle makes, such as Dodge, Ford, etc. Specification on the definition, troubleshooting, and repairs still vary from one make and model to another. Transmission solenoid failure code pertains to the EPC circuit. If this circuit fails, the vehicle will enter into ‘Limp Mode’ or harsh shifting.
How much does it cost to diagnose Ford code p1747?
The cost to diagnose the P1747 FORD code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. How much do you know about cars?
What is an OBD2 code for EPC sensor?
P1747 obd2 code is a trany problem dealing with epc circuit. P1747 obd2 code depicts the operation of the epc circuit and how the epc sensor operates. P1747 Trany press cntl shorted ckt. This code is a trany solenoid failure code that pertains to the epc circuit.
How to check a trany solenoid failure code?
This code is a trany solenoid failure code that pertains to the epc circuit. When this circuit fails, the vehicle will go to a limp mode or harsh shifting including hesitation and stalling. To check verify when the code appears after the code is reset… use a DVOM and check the voltages going to the epc (electronic pressure control) solenoid.
