What is P0773 fault code? What is the description of Gear Shift Solenoid “E” Circuit Electrical Malfunction? How do you fix the fault code P0773 What are the symptoms and causes for the P0773 error code?
What is the P0773 fault code? What does it signify?
The solenoids in automatic transmission cars manage fluid pressure between hydraulic circuits. These solenoids can be identified as A, B, and C. is labeled. If an electrical fault is detected in the E solenoid circuit, the code P0773 is triggered. Depending on the condition of the fault, the PCM may set multiple related codes.
Depending on vehicle operating conditions, the transmission control module TCM opens or closes shift solenoid valve (E) according to the vehicle. The code P0773 will be triggered if there is a fault with the wiring or solenoid.
P0773 fault codes can be found on vehicles of all makes and models, including but not limited to Toyota, Peugeot, Lexus Mazda, Ford, Kia Chrysler, Duramax Honda, Honda, Kia, Chrysler, Duramax, Honda, Lexus, Mazda, Ford, Lexus, Lexus, Lexus, Mazda, Ford, Kia.
What causes the P0773 Fault code?
The code can be used to indicate a malfunction in the “E”, solenoid circuit. In some cases, however, it can also work due to the following issues.
- – A damaged or defective solenoid for the “E” shift
- – Wiring harness for shift solenoid “E”, open or cut
- – A poor electrical connection in the shift solenoid circuit “E”
- – Insufficient transmission oils
- Transmission oil that is extremely dirty
- – Clogged or dirty transmission filter
- – Defective hydraulic control unit for transmission
- – Clogged, blocked hydraulic passages
- Failure of the gearbox mechanically
- – Connectors and cables that are damaged
- – Rarely, defective TCM or PCM
What are the symptoms of the P0773 Fault code?
These symptoms may be present in vehicles with code P0773.
- – Illumination for the check engine light
- – The gearbox is overheated
- – Gearbox slipping
- – Transmission stuck in gear
- – Difficulty shifting gears
- – Increased fuel consumption
- Engine misfire-like symptoms
- – Turn the vehicle into failsafe mode
- – Setting other fault codes in relation to shift solenoids
How do I fix the P0773 fault code?
The following repairs may be able to resolve the P0773 fault code:
- – Replacing “E”, the defective shift solenoid
- Repair of damaged or open cables
- – Reparing the weak electrical connection in shift solenoid valve circuit
- – Topping up the low transmission oil and checking the transmission fluid
- – Drain the transmission oil and replace it with the filter. It may be necessary to disassemble the transmission and clean it to remove any contaminating fluid.
- – Cleaning the transmission fluid passage lines
- – Resolving mechanical problems with the transmission
- – Replacing damaged cables or connectors
- – Replacing an inoperable hydraulic control unit
- – In rare cases, replacement of TCM or PCM
Do not believe mechanics who tell you the transmission must be replaced. This fault can usually be fixed by replacing the solenoid. A professional mechanic can help you verify the accuracy of the repair recommendation and diagnose the problem.
How serious is the P0773 Fault code?
If the transmission is not working properly or the vehicle has gone into failsafe mode, this code means that there is a serious problem. Transmission damage can be prevented by prompt intervention.
