P1385 Mercury Code - Variable Cam Timing Solenoid 'B' Malfunction

Quick Answer

The Variable Camshaft Timing (VTC) solenoid effects the inlet camshaft timing only. Common causes include Low oil level, Cam timing improperly set, Continuous oil flow to the Variable Camshaft Timing (VTC) piston chamber. 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.

Code P1385 Mercury Description

The Variable Camshaft Timing (VTC) solenoid effects the inlet camshaft timing only. The actuator is a helical spline type, which is engine oil driven. It provides 50 degrees of rotation for camshaft adjustment under different types of engine torque and load conditions.
The comprehensive component monitor (CCM) monitors the VCT position for over-retarded camshaft timing. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in a retarded position.

Frequently Asked Questions about P1385 Mercury Code

1. What does the OBDII code P1385 mean on a Mercury vehicle?

The code P1385 indicates a malfunction in the Variable Cam Timing (VCT) Solenoid 'B,' which controls the camshaft timing for optimal engine performance.

2. What are the symptoms of a P1385 code on my Mercury?

Symptoms may include poor engine performance, rough idling, decreased fuel efficiency, hesitation during acceleration, and potentially an illuminated Check Engine Light.

3. What causes the P1385 code in Mercury vehicles?

Common causes include a faulty VCT solenoid, low or dirty engine oil, clogged oil passages, wiring issues like damaged connectors, or a failed PCM (Powertrain Control Module).

4. Can I drive my Mercury with the P1385 code?

While driving with this code may be possible, itâ€™s not recommended as it could lead to reduced performance, fuel inefficiency, and potential long-term engine damage if left unresolved.

5. How do I diagnose the P1385 code in a Mercury?

Diagnosis involves checking the VCT solenoid and its wiring for damage, verifying oil levels and quality, inspecting oil passages, and using a scan tool to monitor camshaft timing behavior.

6. How do I fix the P1385 code on my Mercury?

Repairs may include replacing the VCT solenoid, performing an oil change with the correct viscosity, cleaning oil passages, or repairing damaged wiring or connectors.

7. Does the type of oil I use affect the P1385 code?

Yes, using the incorrect oil type or neglecting oil changes can cause clogging and poor VCT solenoid performance, leading to this code.

8. What is the function of the Variable Cam Timing Solenoid 'B'?

The VCT solenoid 'B' adjusts the timing of the camshaft to optimize engine performance, emissions, and fuel economy based on driving conditions.

9. How much does it cost to repair the P1385 code on a Mercury?

Repair costs vary but typically range from $150 to $400, depending on whether the issue is a simple oil change, solenoid replacement, or wiring repair.

10. Can a dirty VCT solenoid trigger the P1385 code?

Yes, a dirty or clogged VCT solenoid can prevent proper camshaft timing adjustments, resulting in this code. Cleaning or replacing the solenoid may resolve the issue.
