P097DShift Solenoid D Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Open-circuit fault in the drive circuit of shift solenoid D. No maker documents this code publicly. GM's Allison tables that use P097A to P097C stop at shift solenoid 3, and Ford, which has a solenoid D in its 5R110W, 6R80, 6F and 6R140 gearboxes, reports an open SSD under the base code P0765, with P0982/P0983 for ground and power shorts. Any use would follow the CARB rule that every transmission output must be checked for lack of circuit continuity, plus the pattern of the A to C codes: a high-impedance reading confirmed by switching the driver. On Ford's 6R80 and 6F, SSD feeds either CBLR or C456 through a multiplex valve, so an open there would disturb first and upper gears alike.
- What you may notice
- Warning light or MIL on
- Missing gears that depend on solenoid D
- Limp mode in a fixed gear
- Likely causes
- LikelyOpen coil of shift solenoid D
- PossibleDisconnected or corroded terminal in the solenoid D circuit
- PossibleBroken wire in the transmission harness
- RareFaulty driver in the control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
