What does the fault code mean P0981?

Trouble code P0981 indicates problems with the transmission torque converter "E" solenoid control, but in this case refers to the "Shift Solenoid "E" Control Circuit Range/Performance". This means there is a range or performance problem with the electrical circuit that controls solenoid E.

When the engine control system detects that the E solenoid control circuit is out of range or operating erratically, a P0981 code is generated.

Possible reasons

Causes of this problem may include:

  1. Malfunctions of solenoid E: Solenoid E itself may be faulty, causing it to become unstable.
  2. Problems with wiring and connectors: Damage, corrosion or breaks in the electrical circuit connecting the transmission controller and solenoid E.
  3. Transmission controller malfunctions: Problems with the transmission controller that controls the operation of solenoid E.
  4. Problems with other electrical system components: For example, low voltage in the electrical circuit, short circuit and other electrical problems.

To resolve this issue, it is recommended to perform a detailed diagnostic, which may include a circuit resistance test, a voltage test, scanner data analysis, and solenoid E testing. Depending on the diagnostic result, you may need to replace the faulty components, perform wiring repairs, or perform other repair steps. normal operation of the transmission control system.

What are the symptoms of a fault code? P0981?

Symptoms for trouble code P0981 (Shift Solenoid “E” Control Circuit Range/Performance) can vary depending on the specific problem with the E solenoid control system. Here are some possible symptoms:

  1. Gearshift problems: One of the most common symptoms is incorrect or delayed gear shifting. This may include shifting jerks, shift delays, or other transmission anomalies.
  2. Unusual sounds: Problems with the E solenoid can cause unusual noises in the transmission, such as knocking, squeaking, or humming.
  3. Error in Limp mode: In some cases, the vehicle may enter “Limp Mode” (priority operating mode), which will limit performance and speed to prevent additional damage.
  4. Check Engine Light: An illuminated Check Engine Light on your dashboard is a typical sign of a transmission control system problem that requires attention and diagnosis.
  5. Errors in engine operation: A high signal level in the E solenoid control circuit can cause the transmission to malfunction, which in turn can affect engine performance. This may include additional loads, changes in idle speed, or even engine errors.

If you notice these symptoms or the Check Engine Light illuminates on your dashboard, it is recommended that you contact a qualified auto mechanic to diagnose and repair the problem.

How to diagnose a fault code P0981?
