P0746 is a diagnostic trouble code (DTC) for “Pressure Control Solenoid Performance or Stuck Off“.
What does P0746 code mean?
Having a P0746 DTC means that the computer is not fully in control of the transmission or torque convertor, which means you will experience problems ranging from slipping and a non-working transmission, to engine stalling and overheating.
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.
What does pressure control solenoid a performance stuck off mean?
NOTE: In this definition, the words “stuck off”, refers to a condition in which the solenoid that controls the transmission fluid pressure is stuck in the “OFF”, or closed position. In this condition, the pressure of the transmission fluid cannot be controlled, directed, or regulated at all.
Where is the pressure control solenoid?
Where is the transmission pressure control solenoid located? They are usually located within the valve body, the transmission control module, or the transmission control unit. In most cases, solenoids are installed inside of the oil pan, connected to the valve body of the transmission.
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 causes low transmission fluid pressure?
Insufficient transmission fluid levels due to leaks in the system. Slipping or otherwise malfunctioning transmission. Malfunctioning transmission high pressure pump. Defective transmission temperature sensor.
How much is a pressure control solenoid?
The average total cost to diagnose and replace one ranges between $150 and $400. Depending on the make and model of your vehicle, expect to pay between $15 – $100 for a single transmission shift solenoid. A pack can cost $50 to $300.
What is a pressure control solenoid B?
Most automatic transmissions have three solenoid groups that are labeled as A, B, and C. The PCM controls these solenoids to direct fluid at the appropriate pressure to various hydraulic circuits. These pressure changes cause the transmission to change gear ratios at the correct timing.
What is code P0730 mean?
Code P0730 means that the Powertrain Computer or PCM is seeing greater than a specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output RPM Sensor. This can occur during shifting or when driving at steady speeds in the same gear.
What can cause a P0741 code?
Common Problems That Trigger the P0741 Code
- Defective Torque Converter Lockup Solenoid.
- Defective Engine Coolant Temperature Sensor.
- Defective Torque Converter Clutch.
- Defective Valve Body.
- Dirty transmission fluid that restricts the hydraulic passages.
Do CVT transmissions have solenoids?
Zitat von Youtube: According to engine operation. Some modern cvts also have a single on-and-off solenoid for the TCC lockup switch valve.
