P1746 Mercury Code - Electronic Pressure Control Solenoid Low Conditions

Quick Answer

The Diagnostic Trouble Code (DTC) will set when with the engine running in gear at cruise speed and the Powertrain Control Module (PCM) detects that the Torque Converter Clutch (TCC) circuit was shorted to ground. Common causes include Faulty Line Pressure Solenoid, Line Pressure Solenoid harness is open or shorted, Line Pressure Solenoid circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about P1746 Mercury Code

What does the OBDII code P1746 indicate for a Mercury vehicle?

The P1746 code indicates that the Electronic Pressure Control (EPC) solenoid is experiencing low conditions, which can affect the transmission's performance and shifting.

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.
