P3443 Dodge Code - Cylinder 6 Deactivation Control Circuit Low
Quick Answer
The P3443 diagnostic trouble code (DTC) for Dodge vehicles specifically refers to an issue with the Cylinder 6 deactivation control circuit being detected as low. Common causes include Faulty Solenoid: The solenoid responsible for controlling the deactivation of Cylinder 6 may be malfunctioning, causing the low voltage condition, Wiring Issues: There could be a wiring problem, such as a short or open circuit, that is preventing the control circuit from receiving the proper voltage, Sensor Malfunction: A sensor related to the cylinder deactivation system may be faulty, leading to inaccurate voltage readings and triggering the code. 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 P3443 Dodge Description
The P3443 diagnostic trouble code (DTC) for Dodge vehicles specifically refers to an issue with the Cylinder 6 deactivation control circuit being detected as low. This code is typically associated with vehicles equipped with a cylinder deactivation system, which is designed to improve fuel efficiency by deactivating specific cylinders when they are not needed, such as during cruising or low-load conditions.
Common Causes of P3443 Dodge
- Faulty Solenoid: The solenoid responsible for controlling the deactivation of Cylinder 6 may be malfunctioning, causing the low voltage condition.
- Wiring Issues: There could be a wiring problem, such as a short or open circuit, that is preventing the control circuit from receiving the proper voltage.
- Sensor Malfunction: A sensor related to the cylinder deactivation system may be faulty, leading to inaccurate voltage readings and triggering the code.
- ECM Issue: The engine control module (ECM) could be malfunctioning, causing it to incorrectly interpret the voltage signals from the control circuit.
- Mechanical Problem: In some cases, there could be a mechanical issue within Cylinder 6 itself, such as a stuck valve or damaged component, that is affecting the deactivation process.
Symptoms of P3443 Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Performance: The engine may exhibit reduced power, acceleration, or overall performance due to the cylinder deactivation not functioning correctly.
- Rough Idling: The vehicle may experience rough idling or vibrations while at a standstill, which can be a result of the cylinder deactivation system not operating properly.
- Poor Fuel Economy: Since cylinder deactivation is meant to improve fuel efficiency, a malfunction in this system can lead to decreased gas mileage.
- Engine Misfires: If Cylinder 6 is not being deactivated as intended, it could result in engine misfires, which can cause further damage if not addressed promptly.
How to Fix P3443 Dodge
- Diagnose the Issue: Begin by using a scan tool to retrieve the trouble codes and perform a thorough inspection of the cylinder deactivation system to pinpoint the exact cause of the low voltage condition.
- Check Wiring and Connections: Inspect the wiring harness and connections associated with the Cylinder 6 deactivation control circuit for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Test Solenoid and Sensors: Test the solenoid and any sensors related to the cylinder deactivation system to determine if they are functioning correctly. Replace any faulty components.
- Check ECM Functionality: Verify the operation of the engine control module (ECM) by testing its ability to send signals to the cylinder deactivation system. Replace the ECM if necessary.
- Clear Codes and Test Drive: After making the necessary repairs, clear the trouble codes from the vehicle's memory and test drive the vehicle to ensure that the issue has been resolved and that the check engine light does not reappear.
Cost to Fix P3443 Dodge
The cost of repairing a Cylinder 6 deactivation control circuit low issue can vary depending on the specific cause of the problem and the extent of the repairs needed. In general, the cost of parts for this repair could range from $100 to $500, with labor costs adding an additional $100 to $300. This brings the total estimated cost to repair this issue to approximately $200 to $800.

Frequently Asked Questions about P3443 Dodge Code
1. What does the OBDII code P3443 mean for a Dodge vehicle?
P3443 indicates a problem with the Cylinder 6 Deactivation Control Circuit, specifically that the circuit is registering a low voltage condition.
2. What are the common symptoms of code P3443 in a Dodge?
Symptoms may include reduced engine performance, decreased fuel efficiency, a rough idle, or the Check Engine Light being illuminated.
3. What causes the P3443 code to appear?
Common causes include a faulty Cylinder Deactivation Solenoid for Cylinder 6, damaged wiring or connectors in the circuit, a malfunctioning PCM, or insufficient oil pressure.
4. Can low oil pressure trigger the P3443 code?
Yes, low oil pressure can affect the operation of the cylinder deactivation system, potentially causing this code.
5. How is the P3443 code diagnosed?
A technician will typically use a scan tool to confirm the code, inspect wiring and connections, check the solenoid operation, and verify oil pressure levels.
6. Can I continue driving with the P3443 code active?
While the vehicle may still be drivable, ignoring this code can lead to reduced performance and possible engine damage over time.
7. How do you fix the P3443 code on a Dodge?
Repairs may include replacing the Cylinder Deactivation Solenoid, repairing or replacing damaged wiring, cleaning oil passages, or, in rare cases, replacing the PCM.
8. How much does it cost to repair a P3443 code?
Repair costs can vary, but replacing a Cylinder Deactivation Solenoid typically costs between $150 and $300, including parts and labor.
