This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a signal that's too strong from the switch that lets you choose how the car drives, like sport or eco mode.
The P05D2 code is triggered when the powertrain control module (PCM) detects a high voltage signal from the driver mode select switch circuit.
The Driver Mode Select Switch allows the driver to choose different driving modes, such as sport or eco. The PCM monitors the voltage levels from this switch to ensure they are within the expected range. If the voltage is higher than expected, the PCM sets the P05D2 code.
• Check Engine Light is on
• Inability to change driving modes
• Unusual driving behavior
• Faulty driver mode select switch
• Open or shorted wiring in the switch circuit
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Scan the vehicle for codes and freeze frame data.
• Inspect the driver mode select switch and its wiring for damage.
• Test the voltage and ground signals at the switch.
• Replace the driver mode select switch if faulty.
• Repair or replace damaged wiring in the circuit.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Chevrolet Malibu
• Ford F-150
• Toyota Camry
• Regularly inspect the switch and wiring.
• Avoid excessive force when using the switch.
• Keep the vehicle's electrical system well-maintained.
Electrical Circuit Issue
• Avoid using the mode select switch until repaired.
• Consult a professional mechanic for diagnosis.
Check with your vehicle's manufacturer as this may be covered under the powertrain warranty.
This code has been commonly associated with vehicles equipped with advanced driving mode features.
Moderate – It affects the driving experience but is not critical to vehicle safety.
Driving with this issue may not be dangerous, but it can affect vehicle performance. Ensure repairs are completed to maintain optimal vehicle function.
• Vehicle in park with ignition on
• Access to the driver mode select switch
The driver mode select switch is typically located on the dashboard or center console, within easy reach of the driver.
Q: Can I drive my car with the P05D2 code?
A: Yes, but you may not be able to change driving modes, which can affect performance.
Q: How do I reset the P05D2 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
