This summary uses the existing diagnostic information shown in full below.
This code means that a part in your car's transmission isn't getting enough power to work properly. It's like when a toy doesn't have enough battery power to move.
The transmission control module (TCM) has detected that the electrical current in the circuit for the pressure control solenoid 'C' is lower than expected.
The P17C5 code is triggered when the TCM senses that the current in the pressure control solenoid 'C' circuit is below the threshold. This solenoid is responsible for regulating hydraulic pressure within the transmission, and insufficient current can lead to improper transmission operation.
• Transmission slipping
• Harsh or delayed shifting
• Illuminated check engine light
• Faulty pressure control solenoid 'C'
• Damaged or corroded wiring or connectors
• Faulty transmission control module (TCM)
Transmission Control Module (TCM): A computer that controls the transmission's functions.
Solenoid: An electromechanical device that controls fluid flow 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.
• Repair or replace damaged wiring or connectors.
• Replace the faulty pressure control solenoid 'C'.
• Reprogram or replace the TCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Nissan Altima
• Nissan Rogue
• Infiniti QX60
• Regular transmission fluid changes
• Routine inspection of wiring and connectors
• Avoiding excessive towing or heavy loads
Transmission Control Issue
• Do not ignore the check engine light.
• Have the vehicle inspected by a professional if you notice transmission issues.
Check with your vehicle manufacturer; transmission components may be covered under powertrain warranty.
This code has been commonly associated with Nissan and Infiniti vehicles equipped with CVT transmissions.
Moderate – Addressing this issue promptly can prevent further transmission damage.
Driving with a malfunctioning transmission can be unsafe. Address transmission issues as soon as possible.
• Vehicle at operating temperature
• Transmission in drive
The pressure control solenoid 'C' is located inside the transmission, usually accessible by removing the transmission pan.
Q: Can I drive with a P17C5 code?
A: It's not recommended to drive for long periods with this code, as it can lead to further transmission damage.
Q: How can I reset the P17C5 code?
A: After repairs, you can reset the code using an OBD-II scanner. However, if the issue isn't fixed, the code will return.
