P0984 code indicates a problem with the control circuit for Shift Solenoid “E,” involving issues with its range or performance.
P0984 Shift Solenoid “E” Control Circuit Range/Performance
Code symptoms P0984.
– Erratic shifting between gears
– Transmission slipping
– Poor fuel economy
– Check engine light illuminated
Causes of the code P0984.
1. Faulty Shift Solenoid “E”: The shift solenoid “E” itself may be malfunctioning, causing it to not operate within the specified range or performance parameters.
2. Wiring Issues: There could be damaged or corroded wiring connected to the shift solenoid “E”, leading to poor electrical connections and affecting its control circuit performance.
3. Poor Electrical Connection: Loose or poor connections at the shift solenoid “E” or its associated wiring harness may result in inconsistent signals being sent to the vehicle’s control system.
4. Transmission Control Module (TCM) Failure: A malfunctioning TCM can also cause the P0984 trouble code by not properly controlling the shift solenoid “E” circuit.
5. Internal Transmission Problems: Internal transmission issues, such as low transmission fluid levels, dirty fluid, or mechanical failures, may also trigger the P0984 code due to the impact on the shift solenoid “E” operation.
Code Solutions P0984.
1. Check the shift solenoid “E” for physical damage or debris that may be causing it to malfunction. Clean or replace the solenoid as needed.
2. Inspect the wiring connected to the shift solenoid “E” for any signs of wear, damage, or loose connections. Repair or replace any faulty wiring.
3. Ensure that the transmission fluid is at the correct level and in good condition. Dirty or low fluid levels can affect the performance of the shift solenoid.
4. Perform a diagnostic scan using a suitable scan tool to identify any other potential issues with the transmission system that may be causing the code to trigger.
5. Reset the vehicle’s computer system by disconnecting the battery for a few minutes and then reconnecting it. This can sometimes clear the code if it was triggered by a temporary issue.
