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

Quick Answer

The P1385 diagnostic trouble code (DTC) for Lincoln vehicles indicates a malfunction with the Variable Cam Timing (VCT) solenoid 'B'. Common causes include Faulty VCT solenoid 'B': The solenoid itself may be defective and unable to control oil flow properly, Wiring issues: Damaged or corroded wiring connections to the solenoid can prevent proper communication with the PCM, Low engine oil level or poor oil quality: The VCT system relies on clean and adequate oil supply to function correctly. 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 Lincoln Description

The P1385 diagnostic trouble code (DTC) for Lincoln vehicles indicates a malfunction with the Variable Cam Timing (VCT) solenoid 'B'. The VCT system is responsible for adjusting the timing of the camshafts in relation to the crankshaft, optimizing engine performance, fuel efficiency, and emissions. Solenoid 'B' controls the oil flow to the phaser responsible for adjusting camshaft timing on one of the camshafts.

Common Causes of P1385 Lincoln

  1. Faulty VCT solenoid 'B': The solenoid itself may be defective and unable to control oil flow properly.
  2. Wiring issues: Damaged or corroded wiring connections to the solenoid can prevent proper communication with the PCM.
  3. Low engine oil level or poor oil quality: The VCT system relies on clean and adequate oil supply to function correctly.
  4. Camshaft phaser problems: Issues with the camshaft phaser can affect the VCT system's operation.
  5. PCM software issues: Software glitches or malfunctions in the PCM can also trigger the P1385 code.

Symptoms of P1385 Lincoln

  1. Rough idling: The engine may run rough or feel shaky at idle due to incorrect camshaft timing.
  2. Decreased fuel efficiency: A malfunctioning VCT solenoid 'B' can lead to increased fuel consumption.
  3. Engine misfires: Incorrect camshaft timing can cause misfires and a lack of power during acceleration.
  4. Illuminated check engine light: The PCM will trigger the check engine light to alert the driver of the VCT solenoid 'B' malfunction.

How to Fix P1385 Lincoln

  1. Diagnostic scan: Use an OBD-II scanner to retrieve the trouble code and confirm the VCT solenoid 'B' malfunction.
  2. Inspect wiring and connections: Check the wiring harness for any damage or corrosion, and repair or replace as necessary.
  3. Test VCT solenoid 'B': Verify the solenoid's functionality by applying voltage and checking for proper operation.
  4. Check engine oil: Ensure the engine oil level is adequate and the oil is clean and of the correct viscosity.
  5. Replace VCT solenoid 'B': If the solenoid is found to be faulty, replace it with a new one to restore proper camshaft timing control.

Cost to Fix P1385 Lincoln

The cost of repairing a Variable Cam Timing Solenoid 'B' malfunction on a Lincoln vehicle can vary depending on the specific model and year. In general, the price for a new VCT solenoid 'B' can range from $50 to $150, while labor costs can add another $100 to $200. Overall, the total repair cost can be estimated to be between $150 and $350 at an independent repair shop. However, it's important to note that prices may be higher at dealerships or in metropolitan areas. Additionally, diagnostic time and labor rates can also influence the final cost, so it's advisable to inquire with local auto repair shops for a more accurate estimate.
