P0773 Shift solenoid E electrical circuit fault

Shift solenoid E electrical fault

Severity not verified — if the car runs badly, have it inspected

The two sources give the code definition but no severity rating, so the urgency is not verified. A shift fault can leave the car in a fixed gear, so have it checked soon.

P0773 in short

P0773 means the computer found an electrical fault in the circuit of shift solenoid E. TroubleCodes.net lists the wiring, the solenoid, the engine control module or the transmission control module as probable causes. A scan tool that reads the transmission module is needed to tell which.

Shift solenoid E is an electrically controlled valve in the automatic transmission. The computer monitors its circuit and sets P0773 when it sees an electrical fault.

TroubleCodes.net lists wiring, the solenoid and the control modules as probable causes, and notes basic readers cannot run the tests that separate them.

Most likely causes

These are general causes for this code across vehicles. None is specific to one make or model.

  1. Wiring, grounds or connector fault in the solenoid circuit

    Common general cause
    Why it ranks here
    TroubleCodes.net lists wiring, poor connections and bad grounds as probable causes of the solenoid circuit codes.
    What would change this
    Rises if a wire is chafed or a connector is corroded. Falls if the circuit tests normal.

  2. Faulty shift solenoid

    Common general cause
    Why it ranks here
    TroubleCodes.net lists the shift solenoid itself as a probable cause once the wiring tests sound.
    What would change this
    Rises if the solenoid fails a resistance or command test. Falls if it responds correctly.

  3. Low, dirty or wrong transmission fluid

    Common general cause
    Why it ranks here
    TroubleCodes.net lists low or dirty fluid among the first causes for a shift fault and it is the cheapest thing to check.
    What would change this
    Rises if the level is low or the fluid is dark or burnt. Falls if level and condition are correct.

  4. Transmission or engine control module fault

    Possible — needs testing
    Why it ranks here
    TroubleCodes.net lists the control module as a cause but after the wiring and solenoid, so it ranks last.
    What would change this
    Rises if wiring and solenoid test good and the fault stays. Falls if either is faulty.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read every stored code and freeze-frame data with a scan tool that can read the transmission module.

    Low riskTool: scan tool that reads the transmission module

    • IfOther transmission codes are stored

      It meansWork from the first code stored; one fault can set several.

      Go to step 2

    • IfIt is the only code

      It meansCheck the fluid and wiring next.

      Go to step 2

  2. Have the transmission fluid level and condition checked following the maker's procedure.

    Best left to a shop

    Warning:Many transmissions are checked hot with the engine running, and some are sealed with no dipstick. Let a shop do this.

  3. Have the solenoid E circuit tested for opens, shorts and high resistance with a scan tool and a meter.

    Best left to a shop

    Warning:Testing solenoid circuits means working at the transmission connector and sometimes dropping the pan, with hot fluid and a moving drivetrain risk. Let a shop do this.

Symptoms

  • Check engine light
  • Shifting problems

How to fix

  1. Have a shop scan the transmission module for every stored code before any parts are replaced.

  2. Ask a dealer whether a transmission software update or bulletin applies to your VIN.

P0773 questions

Can P0773 be a wiring problem only?

Yes. TroubleCodes.net lists wiring first among the probable causes, so the circuit is tested before parts are replaced.
