Error Code P0771: What It Means & What To Do?

<<See All OBD Codes

What does the error code P0771 signify? This is a generic error code which detects a problem is the automatic transmission. The vehicles use solenoids to automatically fix the flow of fluid transmission so that it matches driving needs which is smooth. Problem can be due to electrical issue or the contamination of solenoid which makes it to stick by itself.

The computer has to control the fluid routing device which is called as shift solenoids if you have to change the gears in automatic transmission. If at least one of them is stuck or does not act proper in off mode, then the P0771 error code will be generated. The shift solenoid is used by the transmission control module so as to control the hydraulic pressure and the vehicle propels correctly down the road. The error code will be set by the TCM if the component malfunctions.

What causes this problem with the Shift Solenoid E Performance or Stuck Off?

• Lacking fluid level.
• Murky or dirty fluid.
• Murky or clogged transmission filter.
• Broken transmission valve body.
• Constrained hydraulic passages.
• Internal errors in the transmission.
• Flawed shift solenoid.
• Corroded connector.
• Wires need repair.
• Broken PCM.

1. Shift Solenoid - Are you looking for the right replacement part? Grab them from Parts Avatar at affordable prices online.
2. Shift valves - A lack of pressure indicates a damaged shift valve. Replace them as preferred.
3. Engine Light - Is the engine light too dim? Get the right component for your vehicle from Parts Avatar.
4. Transmission filter - Look if there are any blockages or muddy particles. Clear them to avoid system malfunction.
5. Transmission valve body - A faulty transmission valve body component needs immediate replacement so that further troubles are not raised.
6. Connector - A faulty or broken connector has to be fixed or replaced immediately to avoid P0771 error code.
7. Powertrain Control Module - A faulty PCM is a generic trouble code in most vehicle. Fix them as soon as possible.

Here are some steps which you should follow in order to diagnose this P0771 fault code:

Before you start the troubleshoot procedure, check for the correct Technical Service Bulletins (TSBs) which is specific for your vehicle by year, model and transmission. It can actually help you in saving time in the long run by guiding you in the right path. Also, you can check for records as to when the filter and fluid of your vehicle was lastly changed.

Fluid & Wiring Inspections

Firstly, you have check for the correct level of fluid and see if their conditions are good. Now, perform a careful inspection of the wires for damages like scraping, rubbing, or burn spots. Also, you have to visually check the connectors and its connections for protection, erosion and damaged pins which includes the wires, connection to solenoids, PCM and transmission pump. You have to check the transmission connection, for safety and essential issues depending on the configuration.

Advanced Steps

The advanced step for each and every vehicle is specific and it needs suitable tools to accomplish diagnosis correctly. The process will need a digital multimeter and certain technical references for your vehicle. Requirement of voltage will differ based on particular models of your vehicle. So, it’s always best to track specific troubleshooting chart.

Continuity Checks

You have to inspect your vehicle for continuity by removing power and the readings of the connections should be set to 0 ohms or as stated by the manufacturer. Suppose there is no resistance or continuity, then it clearly shows that the wires are defective or there is opening or shorted wire which needs to be fixed.

Common Mistakes When Diagnosing the P0771 Code

• Failure of transmission control module.
• Low level transmission fluid.
• Failure of transmission shift solenoid.
• Wire problem.
