What Does P080D Mean?
The Upshift/Skip Shift Solenoid Control Circuit is reading high. The PCM has detected that the voltage in the skip shift solenoid circuit exceeds the expected maximum, usually indicating an open circuit condition, a disconnected solenoid, or a short to battery voltage in the control wire. The solenoid cannot be properly controlled in this state.
Common Causes
30%
Disconnected skip shift solenoid connector
25%
Open circuit in the solenoid control wire
20%
Failed skip shift solenoid with open coil
15%
Short to battery voltage in the solenoid circuit
10%
PCM connector pin pushed back or lost contact
Diagnostic Steps
1
Verify the skip shift solenoid connector is plugged in and fully seated — vibration can work connectors loose over time.
2
Measure solenoid coil resistance at the connector — infinite resistance (OL) confirms an open coil requiring replacement.
3
Check for continuity from the PCM solenoid control pin to the solenoid connector — an open wire needs repair or replacement.
4
Inspect the wiring for damage where it contacts the transmission or runs near other harness bundles that could introduce voltage.
5
Test the PCM output by backprobing the PCM connector and commanding the solenoid — verify the PCM is toggling the control output.

The most common cause of P080D (Upshift/Skip Shift Solenoid Control Circuit High) is: Disconnected skip shift solenoid connector
Typical repair costs for P080D range from $30 to $250, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive. The skip shift is a fuel economy convenience feature. All normal gear selections in the manual transmission are unaffected by this fault.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P080D to identify the root cause.
