P13D6 Code - Sensor For Internal Pressure Of Cylinder 3 Implausible Signal

Quick Answer

The P13D6 diagnostic trouble code (DTC) indicates that the sensor for internal pressure of cylinder 3 is sending an implausible signal to the engine control module (ECM). Common causes include Faulty internal pressure sensor, Wiring or connector issues, ECM malfunction. 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 P13D6 Description

The P13D6 diagnostic trouble code (DTC) indicates that the sensor for internal pressure of cylinder 3 is sending an implausible signal to the engine control module (ECM). This sensor is responsible for monitoring the pressure within the combustion chamber of cylinder 3. When the ECM detects that the signal from this sensor is outside of the expected range, it triggers the P13D6 code.

Common Causes of P13D6

  1. Faulty internal pressure sensor
  2. Wiring or connector issues
  3. ECM malfunction
  4. Engine mechanical problems affecting cylinder 3
  5. Contaminants or debris affecting sensor operation

Symptoms of P13D6

  1. Engine misfires or rough idle
  2. Reduced power and acceleration
  3. Decreased fuel efficiency
  4. Check engine light illuminated
  5. Engine stalling or hesitation

How to Fix P13D6

  1. Diagnose the issue by using a scan tool to read the P13D6 code and perform further testing on the internal pressure sensor, wiring, and ECM.
  2. Inspect the internal pressure sensor and its wiring for any visible damage or contamination. Replace the sensor if necessary.
  3. Check the connector for the internal pressure sensor for corrosion or poor connections. Clean or replace the connector as needed.
  4. Test the ECM to ensure it is functioning properly and communicating with the sensor correctly. Replace the ECM if it is found to be faulty.
  5. Clear the DTC from the ECM's memory and test drive the vehicle to verify that the issue has been resolved.

Cost to Fix P13D6

The cost of repairing the P13D6 code can vary depending on the specific cause of the issue and the labor rates in your area. Generally, replacing the internal pressure sensor can cost between $100 and $300, including parts and labor. If additional components such as the ECM need to be replaced, the total repair cost could be higher. It is recommended to consult with a professional mechanic to get an accurate estimate based on your vehicle's make and model. Keep in mind that diagnostic time and labor rates can also affect the final cost of the repair.
