The P080C: Upshift/Skip Shift Solenoid Control Circuit Low code indicates that the upshift/skip shift solenoid control circuit is receiving lower voltage than expected. This can affect the solenoid’s ability to control gear shifts properly. The issue may be caused by a faulty solenoid, wiring issues, or connector problems.
P080C – Quick Overview
| Code | Information |
|---|---|
| Meaning | P080C: Upshift/Skip Shift Solenoid Control Circuit Low |
| Is it serious? | Yes, low voltage can prevent the solenoid from operating correctly, leading to improper shifting and drivability issues. |
| Possible causes | – Low voltage in upshift/skip shift solenoid control circuit – Faulty solenoid – Wiring or connector issues |
| How to diagnose? | – Test solenoid control circuit for low voltage – Inspect wiring and connectors – Replace faulty components if needed |
P080C Meaning
The P080C code means that the voltage in the upshift/skip shift solenoid control circuit is lower than the acceptable range. This solenoid controls the skip-shift function, which is responsible for skipping gears under specific driving conditions to improve fuel efficiency. A low voltage issue in this circuit can prevent the solenoid from functioning correctly, causing shifting problems.
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 might provide further details. | OBD-II Scanner |
| Test Solenoid Control Circuit for Low Voltage | Use a multimeter or diagnostic scanner to check the voltage in the upshift/skip shift solenoid control circuit. Compare the readings against manufacturer specifications. | Multimeter, Diagnostic Scanner |
| Inspect Wiring and Connectors | Inspect the wiring and connectors leading to the solenoid for damage, corrosion, or loose connections that could cause a low voltage signal. | Flashlight, Multimeter, Safety Gloves |
| Check Battery and Ground Connections | Ensure the battery voltage and ground connections are correct, as weak grounds or poor battery connections can cause low voltage in the solenoid circuit. | Multimeter, Basic Tools |
| Replace Faulty Solenoid | If the solenoid is faulty, replace it with a new one following the manufacturer’s specifications. | Replacement Parts, Wrenches, Screwdrivers |
| Repair Wiring if Necessary | If damaged or corroded wiring is found, repair or replace the wiring to restore proper voltage to the solenoid. | Replacement Wiring, Soldering Tools, Connectors |
| Clear the Code and Test Drive | After repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P080C code has not returned. | OBD-II Scanner |
