The P2655 code indicates a problem with the “A” rocker arm actuator control circuit, specifically that it is open or has lost connectivity. This code is part of the OBD-II system used to monitor various components of your vehicle’s engine performance.
What Does the P2655 Code Mean?
The P2655 code is triggered when the Powertrain Control Module (PCM) detects an issue with the rocker arm actuator’s control circuit. This actuator is crucial for variable valve timing, allowing the engine to optimize airflow and performance under different driving conditions.
What Causes the P2655 Code?
Several factors can contribute to the P2655 code being set, including:
- Failure of the variable valve lift controller assembly
- Wiring issues, such as frayed or shorted wires
- Powertrain Control Module (PCM) failure
What Are the Symptoms of the P2655 Code?
Drivers may notice the following symptoms if their vehicle has triggered the P2655 code:
- Decreased engine performance
- Increased fuel consumption
How Serious Is the P2655 Code?
The P2655 code is considered urgent, as it may lead to significant engine performance issues. Delaying repairs can result in further damage to the engine or related systems, potentially endangering the driver and passengers.
How to Diagnose the P2655 Code
To properly diagnose the P2655 code, a mechanic will typically follow these steps:
- Use an OBD-II scanner to confirm the P2655 code and check for any additional codes.
- Inspect wiring and connectors related to the rocker arm actuator for damage or corrosion.
- Test the variable valve lift controller assembly for proper operation.
- Check the PCM for any faults.
Common Repairs for the P2655 Code
Common repairs that may be required to resolve the P2655 code include:
- Replacing the variable valve lift controller assembly
- Repairing or replacing damaged wiring or connectors
- Replacing the Powertrain Control Module (PCM), if faulty
How Much Does It Cost to Fix the P2655 Code?
The cost to fix the P2655 code can vary widely depending on the specific issue. Basic repairs like wiring fixes may cost a couple of hundred dollars, while a complete replacement of the variable valve lift controller assembly or PCM could run upwards of $1,000 or more. Always consult with a trusted mechanic for a precise estimate.
Can I Fix the P2655 Code Myself?
While some DIY enthusiasts may attempt to fix the P2655 code, it’s important to have a good understanding of automotive systems and diagnostics. If you are not experienced in working with engine components and electrical systems, it’s advisable to seek professional assistance to avoid further complications.
