P0774 - OBD Trouble Code

<<See All OBD Codes

Do you know the probable causes and symptoms of P0774 error code? Do you know how to fix them? This is a general type of error code where the powertrain control module finds an abnormality in the shift solenoid E. if the engine control unit finds an irregular problem

with electric circuit, then the P0774 error code will be set.

In order to control the hydraulic pressure, shift solenoids are used by the transmission control module. It provides various gear ratios which is highly essential to apply clutch packs in the transmission so you can properly boost your vehicle down the road. If the pressure control solenoid is not performing well, then the error code will be set.

What causes this problem with the Shift Solenoid E Intermittent?

• Transmission filter blockage.
• Passage of the hydraulic is limited.
• Internal defects in the transmission.
• Possibilities of a defective shift solenoid.
• Broken connectors.
• Damaged cables.
• Broken PCM.

1. Shift Solenoid - If your shift solenoids are broken or damaged, then you can get the right replacement part from Parts Avatar.
2. Shift Valves - One way to avoid the P0774 error code is by replacing the broken or damaged shift valves.
3. Engine Light - If the engine light is illuminated then they have to be replaced. Get them from Parts Avatar at best prices online.
4. Transmission Filter - Clear off the blocks from the transmission filter so that the vehicle function normally.
5. Transmission Valve Body - A broken component needs immediate replacement so that further troubles are not raised and the P0774 error code disappears.
6. Connector - Check the terminals of the connector if they are damaged or broken. If so, then replace them as desired.
7. Powertrain Control Module - At times, replacing the faulty PCM can help you to get rid of the P0774 error code.

Here are some steps which you should follow in order to diagnose this P0774 fault code:

The diagnosis process can be started with a troubleshoot procedure, and see for the correct Technical Service Bulletins (TSBs) specifically made for your vehicle by year, model and transmission.

This is necessary to guide in the right path thus saving enough time. If you don’t remember when you previously fixed the fluids or filter, you can always check the records.

Fluid & Wiring Inspections

First and foremost, check for the apt level of fluid in your vehicle as well as their conditions. Now, check the wires for damages like scraping, rubbing, or burn spots.

Secondly check the connectors and its related connections, connections to the PCM, transmission pump and solenoid. This is absolutely necessary to ensure protection and other binding issues.

Advanced Steps

Each vehicle has its own specific and advanced procedure and so you’ll need a proper tool to diagnose them. Start processing with the help of a digital multimeter and correct technical reference of your vehicle.

Voltage requirement will change for every vehicle and so it is wise to use a particular troubleshooting chart for your vehicle.

Continuity Checks

You can turn off the power of your vehicle and check for continuity. Set the readings of the connections to 0 ohms or as specified by the manufacturer.

If you don’t find any resistance or continuity, then it is a clear sign that the wires are broken or there is opening or shorted circuit which needs immediately fixation.

Common Mistakes When Diagnosing the P0774 Code

• Failure of the TCM.
• Fluid level in transmission is less.
• Failure of transmission shift solenoid.
• Cabling issue.
