What is P0659 fault code? What is the explanation for the Actuator Supply Voltage “A” Circuit High error code? How can I fix the P0659 fault code What are the causes and symptoms for the P0659 error code?
What is the P0659 Fault code? What does it signify?
The powertrain control module, or PCM, controls only sensors, solenoids and actuators. 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 P0659 fault code can be defined as “Actuator Supply Voltage Circuit “A” Circuit High The meaning of the code can vary depending on the vehicle’s make and model. Transmission problems are the most common result of this code being set. On some European cars, this code can be set using EVAP faults. To ensure proper diagnosis and repair, you should consult your vehicle’s owner’s manual. The failure symptoms you see on your vehicle will help you determine which system/component to work on.
A code P0659 is triggered when the PCM (or the transmission control module, TCM) detects a high-voltage signal in an actuator circuit. The actuator is often associated with an automatic transmission (or gearbox). The code’s “A” label refers more to a component of the CAN (Controller Area Networks) bus circuit than any specific circuit, cable, or part. Depending on the vehicle make and the application, the exact meaning of “A” may differ. The PCM or an associated control module will typically detect the fault in the circuit.
The P0659 fault code can affect any vehicle, including but not limited to: Fiat, Land Rover and Peugeot models, Duramax, GMC Citroen, Jaguars, Audi, Dacia, Volvos, Volkswagen, Audi and Chevrolet.
What is the P0659 Fault Code?
Here are some reasons why P0659 should be set.
- – Damaged connectors or wires that cause an open or short circuit in the input circuits between the engine sensors and the PCM
- – A short circuit or open circuit caused by damaged or wired connectors in one of our control modules
- Ground wires damaged or disconnected at the PCM and other control modules
- – 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 battery failures)
- – PCM and other control modules that are defective
What are the symptoms of P0659 Malfunction Code?
These symptoms may be present in vehicles with code P0659
- – Illumination at the check engine lights
- Problems with automatic transmission shift
- – Transmission gears stuck in any gear or late shifting gears
- – The transmission cannot switch between two-wheel drive and four-wheel drive modes.
- – The transmission cannot switch between economy and sport modes
- Gearbox is not shifting from low to high speed
- – Lower engine power
- – Higher fuel consumption
- – Variations in engine speed
- – Engine misfires, stalling and other issues
- – Hard starting the engine
- – Setting related fault codes
How do I fix the P0659 fault code?
You can make the following repairs to fix the P0659 fault code:
- – Replacing cables and connectors in the PCM and other control modules
- – Replace the ground wires from the PCM or other control module.
- – Repairing blown fuse and investigating the causes
- – Test the power relay of your system, and replace it if necessary
- – Charging and replacing the battery
- – Test the charging system and make any repairs needed
- – Repair of damaged sensors
- – Replacing the defective actuator
- – Replacing defective transmission shift solenoids
- Repairing poor electrical connections and cables, as well as replacing cables and connectors for transmission solenoids.
- – In very rare cases, the replacement of the PCM and other control modules
How serious is the P0659 Fault code?
The severity level of this code is medium. However, it is not recommended that the vehicle be driven in this manner if an automatic transmission fault is involved. The severity of the code can vary depending on the circumstances. The code P0659 does not usually cause visible symptoms. There may be severe symptoms that can impede vehicle operation. To prevent further damage, even if the vehicle is still in operation, P0659 should not be ignored.
