The P0772: Shift Solenoid E Stuck On refers to an issue where shift solenoid “E” is stuck in the “on” position, causing continuous transmission fluid flow, which can lead to erratic shifting or improper gear engagement. This problem can arise from a faulty solenoid, wiring issues, or damaged connectors.
P0772 – Quick Overview
Code | Information |
---|---|
Meaning | P0772: Shift Solenoid E Stuck On |
Is it serious? | Yes, improper shifting can affect drivability and potentially damage the transmission if not addressed. |
Possible causes | – Shift solenoid E stuck on – Faulty solenoid – Wiring or connector issues |
How to diagnose? | – Test solenoid E for stuck-on condition – Inspect wiring and connectors – Replace faulty solenoid if necessary |
P0772 Meaning
The P0772 code indicates that shift solenoid “E” is stuck in the “on” position, meaning it is continuously allowing transmission fluid to flow, leading to improper shifting or gear slippage. This can cause the vehicle to stay in a gear longer than it should, affecting performance and efficiency.
Step-by-step diagnostic guide
Action | Description | Tools Needed |
---|---|---|
Check for Other Codes | Use an OBD-II scanner to check for any additional transmission-related codes that may provide more context to the issue. | OBD-II Scanner |
Test Solenoid E for Stuck-On Condition | Use a multimeter or diagnostic tool to test solenoid E for electrical continuity and proper function. Verify if it is stuck in the “on” position. | Multimeter, Diagnostic Scanner |
Inspect Wiring and Connectors | Visually inspect the wiring and connectors leading to solenoid E for signs of wear, damage, or loose connections that could cause the solenoid to remain on. | Flashlight, Multimeter, Safety Gloves |
Check Transmission Fluid | Ensure the transmission fluid level is correct and the fluid is clean, as low or contaminated fluid can affect solenoid performance. | Transmission Fluid Tester, Dipstick |
Replace Faulty Solenoid | If solenoid E is stuck or malfunctioning, replace it with a new one according to manufacturer specifications. | Replacement Parts, Wrenches, Screwdrivers |
Clear the Code and Test Drive | After replacing the solenoid, clear the code using an OBD-II scanner and take the vehicle for a test drive to confirm that the issue is resolved. | OBD-II Scanner |
Recheck for Codes | After the test drive, rescan the vehicle to ensure the P0772 code has not returned. | OBD-II Scanner |
