When the code P0745 appears in your powertrain control module (PCM), it means that the PCM is not reading the correct electrical voltage drops from the Pressure Control Solenoid as it does its job.
How do I fix code P0745?
What Repairs Will Fix P0745?
- Changing the fluid and filter.
- Replace faulty pressure control solenoid.
- Repair or replace a faulty transmission pump.
- Repair or replace defective transmission valve body.
- Transmission flush to clean passages.
- Cleaning corrosion from connectors.
- Repairing or replacing wiring.
How do you fix a stuck pressure control solenoid?
What repairs can fix the P0747 code?
- Replace a faulty electronic pressure control solenoid.
- Clear blocked transmission fluid passages.
- Refill low or dirty transmission fluid.
- Repair or replace faulty electrical components within the circuit.
- Correct any internal transmission failures.
Where is the transmission pressure solenoid located?
In most cases, solenoids are located inside of the oil pan, connected to the valve body. Depending on what you drive, the technician may be able to replace just the failed shift solenoid.
How do you change a transmission pressure control solenoid?
Zitat von Youtube: First thing we need to do is to remove the negative battery cable from the battery. Next thing we need to do is to remove the air box cover it has 5 Phillips head screws.
How do you test a pressure control solenoid?
Zitat von Youtube: A second test to perform on a pcs is to apply power and ground using a 9 volt square battery. And measure the voltage across the two terminals.
What is pressure control solenoid?
Pressure control solenoids are spring-loaded devices that the engine/transmission control modules use to direct the flow of pressurized transmission fluid to change gears. If the computer is unable to properly control pressure control solenoid ‘A’, then it will store a P0746 diagnostic trouble code.
How much does it cost to replace a shift solenoid?
$200 to $500
Shift Solenoid Repair and Replacement Cost
The overall cost to replace the shift solenoid in an automatic transmission ranges from $200 to $500 for a single solenoid. If the damage requires you to replace the entire solenoid pack the cost increases to between $250 and $700.
What is a pressure control solenoid performance or stuck off?
Diagnostic trouble code (DTC) P0746 stands for “Pressure Control Solenoid “A” Performance/Stuck Off.” This code sets when the transmission control module (TCM) detects an issue with a transmission pressure control solenoid. Some automatic transmissions have more than one pressure control solenoid.
How do you clean a transmission solenoid valve?
Each solenoid valve typically has 1 filter screen on the bottom and several on the sides. Hold a solenoid valve over an absorbent surface, such as a rag. Spray the MAF sensor cleaner through each screen using the red straw attachment on the spray nozzle. Repeat this for each valve.
What happens when a transmission control solenoid goes bad?
If you’re experiencing transmission solenoid troubles, it will become evident in one of four ways: Delayed gear shifting. You can’t downshift, and your engine continues to rev even when applying the brakes. Your transmission gets stuck in neutral.
How do you check a transmission solenoid?
The testing of on/off solenoids is straightforward. Pressure should be applied to the inlet, and if it is normally closed, you should not see pressure at the outlet. Once energized, you should see pressure at the outlet. For a normally open solenoid, the opposite is true.
