Code result
P0986
Shift Solenoid E Control Circuit High
Moderate severity
What it means
TCM detects voltage on shift solenoid E control circuit above threshold. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
