P0986: Shift Solenoid “E” Control Circuit High OBD-II Trouble Code

A high-voltage situation on the shift solenoid E control circuit, likely means that there is an electrical issue somewhere between this solenoid and the ECU. In this scenario, the vehicle’s computer will save a P0986 DTC.

How Serious is the Code?

If there is an electrical issue with the shift solenoid E (the fifth solenoid in the valve body), then a P0986 diagnostic trouble code means you will eventually have serious drivability problems with your vehicle.

Symptoms

Symptoms of a P0986 include:

  • Abrupt gear changes
  • Transmission may not shift into gear

Causes

  • Low or dirty transmission fluid
  • Damaged connectors/wiring
  • Faulty shift solenoid

How to Diagnose the Code?

Diagnosing a P0986 OBDII trouble code should begin with checking the level and condition of the transmission fluid. If the ATF is clean and at the proper level, then the wiring and connectors along the transmission wiring harness should be carefully examined for signs of damage wiring and corroded/broken connectors. If no issues have been found up to this point, the shift solenoid E itself will need to be tested.
