P08E6 Shift Solenoid L Control Circuit/Open

Check engine lightOn

EmissionsRelevant

Drive cycleNot required

Limp modePossible

Open circuit in the control path of shift solenoid L: harness, connector, internal transmission wiring or the coil itself no longer carry current, so the valve cannot be energised. No manufacturer documents this code publicly. Among the documented analogues, Ford reports an open circuit through each solenoid's base code, P0750 for solenoid A, and GM counts it as part of the high-voltage code P0974; a stand-alone open code therefore has no known user. Ford's electrical checks need 0.5 to 5 seconds of mismatch between command and feedback. CARB requires the check. Measuring coil resistance at the transmission connector separates a coil fault from a harness break. P08E4 and P08E5 cover the shorts.

Likely causes

Break in the harness or internal transmission wiring

Open solenoid coil

Connector unlatched or terminal backed out

Symptoms

Check engine or transmission warning light on
Gear range missing or fixed gear
Harsh shifts
