What is the P0658 fault number? What is the explanation for the Actuator Supply Voltage “A” Circuit Low error code? How can I fix the P0658 fault code What are the causes and symptoms of P0658 malfunction code
What is the P0658 fault code? What does it mean
The powertrain controller module (PCM), controls sensors, solenoids actuators, valves and other components. This module is responsible for both monitoring and interoperability to ensure that these components meet the desired values. To ensure that your vehicle has maximum efficiency and performance, all this is necessary.
The code P0658 has been defined as “Actuator Supply Voltage A” Circuit Low The meaning of the code will vary depending upon the vehicle’s make and model. Transmission problems are the most common result of this code being set. This code can also be set on certain European vehicles by using EVAP system faults. For proper diagnosis and repair, it is a good idea to consult the vehicle’s manual. The failure symptoms you see on your vehicle will help you determine which system/component to work on.
The code P0658 will trigger if the PCM or transmission control module (TCM), detects a low-voltage signal in an actuator circuit. The actuator is often associated with an automatic transmission (or gearbox). In the code definition, the “A” label refers to a portion of the CAN bus circuit and not a particular circuit, cable or component. Depending on the vehicle made and the application, the meaning of the “A” label might vary. The PCM or an associated control module will typically detect the fault in the circuit.
P0658 fault codes can be found on vehicles made by: Audi, Dodge and Porsche.
What causes the P0658 Fault code?
Here are some reasons why P0658 should be set.
- – Broken connectors and wires can cause an open circuit or short in the input circuits connecting the engine sensors to PCM.
- – Damaged connectors or wiring that causes an open or short circuit within one of the control module’s control modules
- Ground wires that are damaged or not connected to the PCM or other control module
- – Broken or defective fuse
- – Power relay for defective system
- – Defective transmission shift solenoids
- – Defective actuator
- – Water ingress into control modules and wiring harnesses
- – General electrical issues (such as charging system problems or defective batteries)
- – Control modules or PCMs that are not working properly
What are the P0658 Malfunction Code Symptoms
You may experience the following symptoms if your vehicle has the code P0658:
- – Illumination for the check engine light
- – Problems with Automatic Transmission Shift
- – Transmission shift gears stuck in any or all gears, or transmission gears late
- – Transmission cannot switch between four-wheel-drive and two-wheel-drive modes
- – The transmission cannot switch between economy and sport modes
- Gearbox is not shifting from low gear into high gear
- – Reduced engine power
- – Increased fuel use
- – Engine speed fluctuations
- – Engine misfires or stalling problems
- Difficult starting the engine
- – Other fault codes can be set
How to Fix the P0658 Fault Code
Some repairs that could resolve the P0658 fault code are:
- – Replacing cables and connectors in the PCM and other control modules
- – Replace the ground wires of the PCM and other control modules
- – Replacing blownfuses and researching the root causes
- – Test the power relay of your system, and replace it if necessary
- – Charging and replacing the battery
- – Check the charging system, and make repairs if necessary
- – Replacing damaged sensors
- – Replacing a faulty actuator
- – Replacing damaged transmission shift solenoids
- Repairing poor electrical connections and cables, as well as replacing cables and connectors for transmission solenoids.
- – In rare instances, you may need to replace the PCM or any other control module
How serious is the P0658 fault code?
This code has a medium severity, but the vehicle shouldn’t be driven if it has an automatic transmission fault. The severity of the code can vary depending on the circumstances. The code P0658 does not usually cause visible symptoms. There may be severe symptoms that can impede vehicle operation. Code P0658 should be reported immediately to avoid further damage.
