Code P1746 Mercury Description
The P1746 code for Mercury vehicles indicates an issue with the Electronic Pressure Control (EPC) solenoid, specifically that the solenoid is operating at a lower level than expected. The EPC solenoid is a crucial component of the transmission system, responsible for regulating the hydraulic pressure within the transmission. When the EPC solenoid is not functioning properly, it can lead to a variety of issues with the transmission, affecting the vehicle's overall performance.
Common Causes of P1746 Mercury
- Faulty EPC solenoid
- Wiring issues or electrical connection problems
- Low transmission fluid levels
- Contaminated transmission fluid
- Mechanical issues within the transmission system
Symptoms of P1746 Mercury
- Erratic shifting or slipping gears
- Harsh shifting or delayed engagement
- Reduced fuel efficiency
- Poor acceleration
- Check Engine Light illuminated
How to Fix P1746 Mercury
- Begin by conducting a thorough inspection of the EPC solenoid, wiring, and connections to identify any visible signs of damage or corrosion.
- Check the transmission fluid levels and condition, topping off if necessary or performing a fluid flush if it is contaminated.
- Test the EPC solenoid using a multimeter to determine if it is functioning within the specified parameters.
- Replace the EPC solenoid if it is found to be faulty, ensuring proper installation and secure connections.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P1746 Mercury

What are the common symptoms associated with the P1746 code?
Common symptoms include harsh or erratic shifting, slipping transmission, illuminated check engine light, and reduced engine performance.
What could cause the P1746 code to trigger?
Possible causes include a faulty EPC solenoid, wiring issues, low transmission fluid levels, or a malfunctioning transmission control module (TCM).
How can I diagnose the P1746 code effectively?
To diagnose the P1746 code, check the transmission fluid level and condition, inspect the wiring and connectors for damage, and test the EPC solenoid for proper operation using a multimeter.
What are some common repairs for the P1746 code?
Common repairs include replacing the faulty EPC solenoid, repairing or replacing damaged wiring or connectors, and ensuring the transmission fluid is at the proper level and in good condition.
Can low transmission fluid contribute to the P1746 code?
Yes, low transmission fluid can lead to inadequate pressure for the EPC solenoid, triggering the P1746 code and causing shifting issues.
Is it safe to drive a vehicle with the P1746 code?
It is not recommended to drive a vehicle with the P1746 code, as it may lead to further transmission damage or failure if not addressed promptly.
How can I prevent the P1746 code from recurring?
To prevent the P1746 code from recurring, regularly check and maintain proper transmission fluid levels, perform routine maintenance, and address any transmission issues immediately.
What should I do if I’ve replaced the EPC solenoid but the P1746 code persists?
If the P1746 code persists after replacing the EPC solenoid, further diagnosis is needed to check for wiring issues, TCM faults, or other underlying transmission problems.
