The P0982: Shift Solenoid ‘D’ Control Circuit Low refers to a problem where the shift solenoid ‘D’ control circuit is receiving lower than expected voltage. This can prevent the solenoid from functioning properly, leading to transmission shifting issues and affecting vehicle performance.
P0982 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0982: Shift Solenoid ‘D’ Control Circuit Low |
| Is it serious? | Yes, low voltage can cause improper shifting and poor transmission performance. |
| Possible causes | – Low voltage in the shift solenoid ‘D’ control circuit – Faulty shift solenoid ‘D’ – Wiring or connector issues |
| How to diagnose? | – Check the circuit for low voltage – Inspect wiring and connectors – Replace the shift solenoid ‘D’ if necessary |
P0982 Meaning
The P0982: Shift Solenoid ‘D’ Control Circuit Low code indicates that the voltage in the shift solenoid ‘D’ control circuit is below the required level. Low voltage can cause the solenoid to malfunction, leading to improper transmission fluid regulation and shifting problems, including delayed or rough shifting.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional fault codes that may provide more insight into the low voltage issue. | OBD-II Scanner |
| Test for Low Voltage | Use a multimeter to check the voltage in the shift solenoid ‘D’ control circuit. Compare the voltage readings with manufacturer specifications to determine if they are too low. | Multimeter |
| Inspect Wiring and Connectors | Inspect the wiring and connectors for signs of damage, corrosion, or loose connections that may be causing low voltage in the solenoid circuit. | Flashlight, Multimeter |
| Test the Solenoid | Test the shift solenoid ‘D’ for proper operation. Replace the solenoid if it is malfunctioning or receiving low voltage. | Diagnostic Tool, Replacement Solenoid |
| Clear the Code and Test Drive | After making repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the system to ensure the P0982 code does not return after the test drive. | OBD-II Scanner |
