What is the P0753 fault number? What is the description of Gear Shift Solenoid “A” Electrical Failure? How can you fix P0753 fault code What are the causes and symptoms of the P0753 error code?
What is the P0753 fault code? What does it signify?
A P0753 code means that the powertrain control module, PCM, has detected an electric fault in shift solenoid A.
Computer-controlled automatic transmissions use shift solenoids in order to adjust gear ratios. Three solenoids are common to automatic transmissions: A, B, and C. These solenoids control the gear ratios.
The shift solenoids, managed by the PCM or transmission control module (TCM), are used to adjust the transmission gear ratio. This is done by directing the transmission fluid to various hydraulic circuits. The solenoid controlling the transmission directs the pressure fluid to the right hydraulic circuit according to vehicle speed. All transmission components are in their correct positions due to the hydraulic circuit pressure. Different gear combinations can increase engine performance.
A code P0753 will be set if the PCM/TCM detects an electrical fault within the “A” shift solenoidcircuit. To notify the driver, however, the check engine lamp is activated on the instrument cluster. A transmission warning or overdrive light might also be on.
The P0753 fault code can affect vehicles of all makes and models, including but not limited to Toyota, Chevrolet, Dodge Lexus, Lexus, Volvos, Mazda, Jeeps, Chrysler, Ford, Hyundai, Lexus, and Honda.
What Are the Possible Causes of P0753 Fault Codes?
Here are some reasons why P0753 should be set.
- – An electrical fault has occurred in the solenoid circuit for the “A” shift.
- – Defective “A” shift solenoid
- – Oil with low or no transmission
- – Use of incompatible or unsuitable transmission fluid
- – Clogged or dirty transmission filter
- – Hydraulic fluid lines clogged
- – Connectors and wiring that are damaged, burnt, disconnected, or corroded
- – Hydraulic control unit for transmission failure
- – Faulty or clogged transmission pump
- – Other mechanical faults with the gearbox
- – Software Update Required for Defective Transmission Control Module (TCM) or PCM.
What are the symptoms of P0753 Malfunction Code?
You may experience the following symptoms if your vehicle has the code P0753:
- – Illumination for the check engine light
- – The transmission warning light is on
- – Gearbox slip
- Gearbox can be stuck in any gear (especially 1-2).
- – Incorrect or delayed gear changes
- – Engine stalling in the event that the vehicle is close to stopping
- – While in gear, the vehicle doesn’t move.
- – Increased fuel consumption
- – The gearbox is overheated
- – The engine might experience misfire-like symptoms in some cases.
- – A PCM can go into failsafe mode
How to Fix the P0753 Fault Code
This is the most common error in repairing this code.
The following repairs may be able to resolve the P0753 fault code:
- To determine if the codes will return, it is important to first clear them all.
- – Clean the transmission and fill the transmission with fluid.
- – Replacing your transmission filter
- – Replacing damaged wires or connectors to the solenoid
- – Cleaning corrosion on connectors
- – Replacing the defective “A” shift solenoid
- – Replacing a defective hydraulic control unit
- – Removing or replacing blockages in the pump
- – Reprogramming of the TCM or PCM
How serious is the P0753 Fault code?
The severity of the code starts at a mild level but can escalate to more severe levels if it isn’t corrected promptly. It can cause serious problems to the vehicle’s driving ability. Transmissions can overheat, causing problems with gear shifting or even preventing the transmission from changing gears. The PCM may enter fail-safe mode which may limit engine speed and make it difficult to drive. It is important to repair the fault as soon possible, as this will lead to high repair costs.
