The P2717: Pressure Control Solenoid ‘D’ Intermittent code indicates that the Transmission Control Module (TCM) has detected an intermittent fault in pressure control solenoid ‘D’. This could be caused by a faulty solenoid, loose or damaged wiring, or issues with the control module. An intermittent problem often results in inconsistent transmission operation, leading to erratic gear shifting and potential transmission damage if not addressed.
P2717 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2717: Pressure Control Solenoid ‘D’ Intermittent |
| Is it serious? | Yes, as intermittent faults can lead to erratic shifting, slipping, and may cause wear or damage to the transmission due to inconsistent hydraulic pressure control. |
| Possible causes | – Intermittent issue with pressure control solenoid ‘D’ – Faulty solenoid or wiring – Control module problems |
| How to diagnose? | – Inspect and test pressure control solenoid ‘D’ for intermittent faults – Check wiring and connectors for loose connections – Verify control module operation – Replace faulty components as needed |
P2717 Meaning
The P2717: Pressure Control Solenoid ‘D’ Intermittent code means that the TCM has detected an irregular and fluctuating signal from pressure control solenoid ‘D’. This kind of issue typically indicates a loose connection, worn or damaged solenoid, or internal wiring faults, which can cause inconsistent hydraulic pressure control, resulting in erratic transmission shifts or slipping.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to determine if there are any additional codes that might help diagnose related issues with the transmission or electrical systems. | OBD-II Scanner |
| Test Pressure Control Solenoid ‘D’ for Intermittent Faults | Use a diagnostic scanner capable of actuating pressure control solenoid ‘D’. Observe its behavior over time to detect intermittent faults. If it fails to respond correctly at any point, it may be the cause of the issue. | Diagnostic Scanner |
| Inspect Wiring and Connectors | Inspect all wiring and connectors connected to solenoid ‘D’. Look for signs of loose connections, frayed wires, corrosion, or damaged insulation. Carefully manipulate the wiring while observing for changes in the solenoid response, which could indicate an intermittent issue. | Flashlight, Multimeter |
| Perform Voltage and Continuity Checks | Use a multimeter to check for proper voltage at the solenoid when activated by the TCM. Additionally, test continuity to ensure there are no breaks or short circuits in the wiring. Fluctuations in readings may indicate an intermittent electrical issue. | Multimeter |
| Test Solenoid Resistance | Measure the resistance of solenoid ‘D’ using a multimeter. Compare the reading with the manufacturer’s specifications. Deviations from the expected resistance could suggest internal wear or damage, leading to intermittent operation. | Multimeter |
| Inspect Control Module Operation | Verify that the TCM is sending appropriate signals to pressure control solenoid ‘D’. Use a diagnostic tool to monitor TCM commands to solenoid ‘D’ and ensure that it is operating correctly. Intermittent control from the TCM could indicate a software or hardware issue within the module. | Diagnostic Scanner |
| Check for Temperature-Related Issues | Determine if the intermittent fault occurs at certain temperatures, such as after the transmission has heated up. Heat can exacerbate electrical issues, leading to temporary disconnections or shorts in wiring or connectors. | Thermometer, Diagnostic Scanner |
| Replace Faulty Components | If solenoid ‘D’ is found to be faulty or if wiring/connectors show signs of intermittent failure, replace these components. Ensure that all replacements match the manufacturer’s specifications. | Replacement Solenoid, Wiring |
| Secure All Connections | After replacing faulty components, ensure that all connectors are securely attached and that wiring is properly routed and free of potential interference or movement that could cause disconnection. | Mechanic Tools, Zip Ties |
| Clear the Code and Test System | After repairs, use an OBD-II scanner to clear the P2717 code. Conduct a thorough test drive to verify that the transmission shifts smoothly and that the intermittent issue with solenoid ‘D’ has been resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the vehicle to ensure that the P2717 code has not returned and confirm that pressure control solenoid ‘D’ is functioning properly without intermittent faults. | OBD-II Scanner |
