P2775 Fault Code

Upshift Switch Circuit Range/Performance

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2775 fault code indicates an issue with the upshift switch circuit range or performance. This switch is typically used in automatic transmission systems to signal when the transmission should shift to a higher gear. If the switch's performance is outside the expected parameters, it can lead to issues with gear shifting and transmission efficiency.

What are the symptoms of the P2775 code?

Symptoms associated with the P2775 code can include:

• Erratic transmission shifting behavior
• Inability to change gears smoothly or at all
• Illuminated check engine light
• Increased fuel consumption due to inefficient shifting
• Slipping or hesitating during acceleration

What causes the P2775 code?

Common causes for the P2775 code may include:

• Faulty upshift switch or sensor
• Damaged wiring or poor electrical connections
• Issues with the transmission control module (TCM)
• Electrical shorts or open circuits
• Mechanical problems within the transmission

How to fix P2775?

To resolve the P2775 fault code, the following steps should be taken:

• Inspect the upshift switch and wiring for signs of damage or wear
• Test the upshift switch to ensure it is functioning correctly
• Repair or replace any damaged wiring or connectors
• If necessary, reprogram or replace the TCM
• Clear the fault codes and conduct a test drive to confirm that the issue is resolved
