The P1746 Ford diagnostic trouble code indicates that there is a low condition detected in the Electronic Pressure Control (EPC) solenoid circuit. The EPC solenoid is responsible for regulating the hydraulic pressure in the transmission, which is …

2005年1月19日 · 1999 - 2003 7.3L Power Stroke Diesel - P1746 EPC Solenoid Open Circuit - Need a little input.I'm looking at a 97 F-250 Power Stroke that has an intermittent no start problem.The owner has been pulling his hair out troubleshooting it.I have the P1746 trouble code to work with which I believe is EPC Solenoid Open...

2015年3月8日 · 1999 - 2016 Super Duty - P1746 Transmission DTC - hello all, i have a 4r100 in my 2000 f250 7.3. I am getting a P1746-EPC Solenoid, open circuit. Does this mean this particular solenoid in the solenoid body has failed and should i replace the solenoid body?

2013年2月22日 · So bought an XCAL 2 and read the code on the "o/d off" flashing and it is P1746 EPC NOID Open Circuit. Which from researching on this site I believe means I did not fully plug in the electrical connector harness-- elec. pressure control solenoid is not sending a signal.

2014年3月29日 · Codes p1746 and p1747 are both related to the EPC electrical circuits. These codes are only generted by and electrical fault. Inspect the wiring connector at the transmission. You may have have to use a mirror to inpsect the connector on the transmission itself.

2007年2月26日 · P1746 b EPC PCM failure — electronic pressure control driver. Current through EPC circuit is checked and compared after a time delay. An error will be noted if tolerance is exceeded during KOEO and continuous On-Board Diagnostics. Open circuit — causes maximum electronic pressure control, harsh engagements and shifts. May flash TCIL.

Engine started, vehicle in gear, and the PCM detected the Electronic Pressure Control (EPC) solenoid circuit indicated "open". This fault can cause harsh engagements and shifts.

Code P1746 EPC Circuit Short to Ground 1995-2004 F Series/1996-2004 Taurus/ Sable March, 2008 It’s easy to confuse the wording of these codes as an internal PCM failure. The factory manual along with aftermarket repair literature will define P1746 as EPC Control Driver Failure or PCM Failure-Open PCM Output Driver Failure.

2015年10月4日 · DTC P1746 indicates electronic pressure Control (EPC) solenoid open circuit (low input). Suspect open in wiring harness & connectors or faulty solenoid. Possible causes: Solenoid interconnect molded lead frame not fully seated on solenoid pack or bulkhead.

P1746 indicates an issue with the Electronic Pressure Control (EPC) Solenoid, which regulates hydraulic pressure in the transmission. A "low condition" means the solenoid is not functioning properly, leading to improper pressure control and potential transmission performance issues. Faulty EPC solenoid.
