P0983Shift Solenoid D Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- High-voltage fault in the control circuit of shift solenoid D. Ford defines it narrowly as SSD short to power; the open circuit stays with P0765. On the 6R140 the solenoid outputs are run by a smart driver chip (ADLER) that does the open and short checks itself, while older units use a feedback line from the output stage; both need 0.5 to 5 s. Since SSD on Ford six-speeds controls the low/reverse clutch, either alone or through the multiplex valve, a constant power short can apply that clutch at the wrong time. The 2020–2023 gasoline summary keeps the same assignment. GM documents no P0983 for its geared automatics, and Ferrari uses it for an actuator 3 sensor reading too high. Ground faults are P0982.
- What you may notice
- MIL on, default gear
- Clunk or tie-up feel if the low/reverse clutch applies unintentionally
- Upper gears blocked
- Likely causes
- LikelySolenoid D control wire shorted to a supply
- PossibleSolenoid D with shorted windings
- PossibleConductive contamination between neighbouring pins
- RareFaulty smart driver or output stage in the module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
