P0986
Shift Solenoid E Control Circuit High
Transmission
Generic OBD-II
Medium
What it means
P0986 means the transmission control module detected high voltage (often an open or short to power) on the control circuit for shift solenoid E. That solenoid helps engage gears hydraulically, so the fault typically causes poor shifting or a protective limp mode. The usual causes are a failed solenoid, wiring problems, or a bad connector.
Medium
Can I keep driving? Limited — expect harsh or missed shifts, possibly limp mode; drivable briefly but have it repaired before the transmission takes damage.
Common symptoms
What you'll notice
- Poor shifting or failure to shift through all gears
- Harsh or delayed gear changes
- Transmission in limp/failsafe mode
- Check-engine light on
Common causes
Most likely first
- Failed shift solenoid ELikely
- Wiring fault in the solenoid circuit (short to voltage or open)Common
- Loose or corroded connector at the transmissionCommon
- Low or contaminated transmission fluidLess often
- Faulty transmission control module (TCM)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and verify transmission fluid level and condition.
- Inspect the transmission connector and wiring to shift solenoid E for a short to power, opens, or corrosion.
- Measure shift solenoid E resistance against spec; replace if out of range.
- Repair damaged wiring, clear the code, and road-test through all gears.
- If the solenoid and circuit are good, have the TCM diagnosed.
FAQ
Quick answers
Is it safe to drive with P0986?+
Only for short trips. Limp mode and harsh shifts are hard on the transmission, so keep driving to a minimum until it's fixed.
Can I just clear P0986?+
You can, but the code returns once the high-voltage fault is seen again. Fix the solenoid or wiring for a lasting repair.
