The P080B: Upshift/Skip Shift Solenoid Control Circuit Range/Performance code indicates a problem with the range or performance of the upshift/skip shift solenoid control circuit. This solenoid helps manage gear shifts, and any performance or range issue can lead to improper shifting. The issue may stem from a faulty solenoid, wiring problems, or connector issues.
P080B – Quick Overview
| Code | Information |
|---|---|
| Meaning | P080B: Upshift/Skip Shift Solenoid Control Circuit Range/Performance |
| Is it serious? | Yes, as it can lead to improper shifting, affecting drivability and performance. |
| Possible causes | – Range or performance issues with upshift/skip shift solenoid – Faulty solenoid – Wiring or connector issues |
| How to diagnose? | – Test upshift/skip shift solenoid for performance – Inspect wiring and connectors – Replace faulty solenoid if necessary |
P080B Meaning
The P080B code signifies that the transmission control module (TCM) has detected an issue with the performance or range of the upshift/skip shift solenoid. This solenoid controls the skip-shift feature, which is designed to optimize fuel efficiency by skipping certain gears under specific driving conditions. A malfunction here can result in incorrect or erratic gear shifts.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other transmission or solenoid-related codes that may provide additional insights. | OBD-II Scanner |
| Test Upshift/Skip Shift Solenoid for Performance | Use a multimeter or diagnostic scanner to test the solenoid’s performance, ensuring it operates within manufacturer specifications. Look for voltage or resistance issues. | Multimeter, Diagnostic Scanner |
| Inspect Wiring and Connectors | Inspect the wiring and connectors leading to the upshift/skip shift solenoid for damage, loose connections, or corrosion that may affect the solenoid’s performance. | Flashlight, Multimeter, Safety Gloves |
| Check Transmission Fluid | Verify that the transmission fluid is at the correct level and that it is clean. Low or dirty fluid can affect solenoid operation. | Transmission Fluid Tester, Dipstick |
| Replace Faulty Solenoid | If the solenoid is found to be faulty or outside of the proper operating range, replace it with a new one according to manufacturer specifications. | Replacement Parts, Wrenches, Screwdrivers |
| Clear the Code and Test Drive | After replacing or repairing the solenoid, clear the code using an OBD-II scanner and test drive the vehicle to ensure the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P080B code has not returned. | OBD-II Scanner |
