Common Causes of P1104 Mitsubishi

  1. Electrical issues: Problems with the wiring or connections to the wastegate solenoid can prevent it from functioning properly.
  2. Vacuum leaks: Any leaks in the vacuum lines that control the wastegate solenoid can lead to erratic performance.
  3. Mechanical failure: The wastegate solenoid itself may be defective or worn out, requiring replacement.
  4. Clogged/dirty components: Accumulated dirt or debris in the turbocharger system can hinder the operation of the wastegate solenoid.

Symptoms of P1104 Mitsubishi

  1. Loss of power or acceleration: A malfunctioning wastegate solenoid can lead to a decrease in engine performance, resulting in sluggish acceleration and reduced power output.
  2. Poor fuel efficiency: When the turbocharger is not operating at optimal levels due to a faulty wastegate solenoid, it can cause the engine to consume more fuel than usual.
  3. Engine overheating: In some cases, a malfunctioning wastegate solenoid can cause the engine to run hotter than normal, leading to potential overheating issues.
  4. Strange noises: A failing wastegate solenoid may produce unusual noises, such as whistling or hissing sounds, coming from the engine compartment.

How to Fix P1104 Mitsubishi

  1. Diagnose the issue: Use a diagnostic scanner to read the trouble code and determine if the wastegate solenoid is the root cause of the problem.
  2. Inspect electrical connections: Check the wiring and connections to the wastegate solenoid for any signs of damage or corrosion.
  3. Test vacuum lines: Ensure that the vacuum lines leading to the wastegate solenoid are free of leaks or obstructions.
  4. Replace wastegate solenoid: If the solenoid is found to be faulty, it will need to be replaced with a new unit.
  5. Clear codes and test drive: After repairs are completed, clear the trouble code from the vehicle's computer and test drive the vehicle to ensure that the issue has been resolved.

Cost to Fix P1104 Mitsubishi

The cost of repairing a turbocharger wastegate solenoid can vary depending on the make and model of the vehicle, as well as the labor rates in your area. On average, the parts for this repair can range from $100 to $300, while the labor costs can be between $100 and $200. This puts the total repair cost in the range of $200 to $500. It is important to keep in mind that additional costs may be incurred if other components in the turbocharger system are found to be damaged and in need of replacement. It is recommended to consult with a trusted mechanic or dealership for a more accurate estimate based on your specific vehicle.

P1104 indicates a problem with the Turbocharger Wastegate Solenoid, which controls the wastegate to regulate turbo boost pressure.

2. What are the common symptoms of the P1104 code?

Symptoms may include reduced engine performance, poor fuel efficiency, excessive turbo lag, or the Check Engine Light illuminating.

3. What causes the P1104 code to appear?

Common causes include a faulty turbocharger wastegate solenoid, damaged wiring or connectors, vacuum leaks, or issues with the turbocharger itself.

4. Can I drive my Mitsubishi with a P1104 code?

Driving with a P1104 code is not recommended, as it can lead to reduced performance and potential engine damage if the turbocharger system is not functioning properly.

5. How do I diagnose the P1104 code?

Start by inspecting the wastegate solenoid, wiring, and vacuum lines for damage or disconnections. A scan tool can help monitor solenoid function and turbo boost pressure.

6. How is the P1104 code fixed?

Repairs may include replacing the turbocharger wastegate solenoid, repairing damaged wiring, fixing vacuum leaks, or addressing turbocharger issues.

7. How much does it cost to fix the P1104 code?

Repair costs vary but typically range from $150 to $400, depending on whether you need a solenoid replacement or additional repairs.

8. What happens if the P1104 code is ignored?

Ignoring the code can lead to further damage to the turbocharger system, decreased engine performance, and higher repair costs over time.

9. Can a dirty or clogged wastegate solenoid cause the P1104 code?

Yes, a dirty or clogged solenoid can restrict its operation, leading to the P1104 code and improper turbo boost regulation.

10. Will clearing the P1104 code fix the problem?

Clearing the code with a scan tool will only reset the Check Engine Light temporarily. The underlying issue must be repaired to prevent the code from returning.
