P0984Shift Solenoid E Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Range/performance fault in the drive circuit of shift solenoid E. Ford checks SSE with P0770, P0985 and P0986 only, GM's documented tables never reach letter E, and even Ferrari's DCT list, which reuses most of its neighbours, skips P0984. The one codegenau source is FCA: in recall S55 for the 9-speed front-drive transaxle it names P0984 together with P0975, P0978 and P0981. Under old TCM software, a range sensor harness with poor crimps and intermittent high resistance could set them; with new software the same fault shows as P0901, and these four codes then point to a separate transmission problem. Otherwise the code rests only on the CARB rule for transmission output checks. Low/high are P0985/P0986.
- What you may notice
- Sudden neutral or loss of drive (FCA 9-speed)
- MIL or transmission warning on
- Limp mode
- Likely causes
- LikelyRange sensor harness with weak crimps (FCA 9-speed recall)
- PossibleTCM software below the recall level
- PossibleInternal transmission fault when the code returns after the update
- RareFaulty driver stage in the control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
