This summary uses the existing diagnostic information shown in full below.
This code means that one of the parts in the car that helps control the pressure in the transmission is using too much electricity.
The transmission uses solenoids to control hydraulic pressure, and this code indicates that the current going to solenoid 'C' is higher than expected.
The P17D5 code is triggered when the Powertrain Control Module (PCM) detects that the electrical current in the circuit of the pressure control solenoid 'C' is higher than the manufacturer's specifications. This could be due to a short circuit, a faulty solenoid, or an issue with the wiring.
• Check Engine Light is on
• Transmission may not shift properly
• Poor fuel economy
• Faulty pressure control solenoid 'C'
• Short circuit in the wiring harness
• Faulty PCM
PCM: Powertrain Control Module, the computer that controls engine and transmission functions.
Solenoid: An electromechanical device that controls the flow of fluid in the transmission.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the pressure control solenoid 'C' for proper operation.
• Replace the faulty pressure control solenoid 'C'.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools
$150 - $400
Moderate
• Volkswagen Jetta
• Audi A4
• Skoda Octavia
• Regular maintenance of the transmission system.
• Inspect wiring and connectors periodically.
• Use quality transmission fluid.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the transmission system checked by a professional.
• Avoid driving the vehicle aggressively until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on transmission components.
This code has been associated with transmission issues in certain models, particularly those with high mileage.
Moderate – While the vehicle may still be driveable, ignoring the issue could lead to more severe transmission problems.
Driving with a faulty transmission can be dangerous and may lead to further damage.
• Vehicle at operating temperature
• Transmission in drive mode
The pressure control solenoid 'C' is located inside the transmission, usually accessible by removing the transmission pan.
Q: Can I drive with a P17D5 code?
A: It's not recommended as it may cause further damage to the transmission.
Q: How can I reset the P17D5 code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is fixed first.
