Guide To P0773 OBD Error Code Solutions

<<See All OBD Codes

How does the OBD error code P0773 occur? What are its symptoms and causes? The hydraulic pressure is controlled by the TCM. This is necessary to apply clutch packs as it gives different gear ratios which is necessary to push your vehicle down the lane. If the pressure control solenoid is not performing well, then the error code will be set.

Based on your operating condition, the shift solenoid will be turned on or off by the transmission control module. There will be an abnormality in the gear ratio if the wire or solenoid malfunctions. This is a generic type of trouble code in the solenoid valve which replies to signals informing which gear has to be started. This DTC will indicate an issue with the solenoid valve which responds to signals saying them as which gear position to start.

What causes this problem with the Shift Solenoid E Electrical?

• The fluid is either muddy or polluted.
• Dirty transmission filter or it is blocked.
• Transmission valve body is broken.
• The hydraulic passage is blocked.
• Internal faults in the transmission.
• Shift solenoid failure.
• Connector is corroded or broken.
• PCM is damaged.

Here are some steps which you should follow in order to diagnose this P0773 fault code:

You can initially begin with a troubleshoot method and examine for the correct Technical Service Bulletins that is precisely designed for your vehicle by year, model and transmission. This can help you in the long run by saving time as it guides you down the right path. If you clearly don’t remember check the records as when you lastly changed the filter and fluids.

Fluid & Wiring Inspections

• Firstly, ensure that the fluid is not contaminated and is available at the right level. Check for injuries like scraping, rubbing, or burn spots by visually inspecting these elements as well as the connectors and its connections to ensure safety. Visual inspection must also include the wires, connectors, transmission solenoid, transmission pump and PCM. Check the transmission connection so as to ensure security and important issues.

Advanced Steps

• Each and every vehicle have their own procedure as they are specific and you have to use proper diagnostic tools for the process. In order to start the process, you have to use a digital multimeter and appropriate technical references. It is always best to use your vehicle specific troubleshooting chart.

Continuity Checks

• Remove the power from the circuit and check for continuity in your vehicle where the readings of your vehicle must be set to 0 ohms. You can also use manufacture specified reading. If you find no resistance or continuity, then it is very much clear that there are damaged wires which needs to be replaced.

Common Mistakes When Diagnosing the P0773 Code

• Defective TCM.
• Fluid level is less.
• Transmission shift solenoid has failed.
• Wire problem.
