What Does P080C Mean?
The Upshift/Skip Shift Solenoid Control Circuit is reading low. The PCM has detected that the voltage or current in the skip shift solenoid circuit is below the expected minimum. This typically indicates a short to ground in the solenoid control circuit or a solenoid coil with shorted windings, reducing the circuit resistance below normal.
Common Causes
30%
Skip shift solenoid with internally shorted coil windings
30%
Short to ground in the solenoid control wire
20%
Corroded or water-damaged solenoid connector
12%
Wiring chafed against transmission case or bracket
8%
PCM output driver pulling the line low
Diagnostic Steps
1
Disconnect the skip shift solenoid connector and measure coil resistance — significantly lower than specification confirms a shorted coil.
2
With the solenoid disconnected, check if the code clears and the PCM sees normal circuit voltage — this isolates the fault to the solenoid versus wiring.
3
Inspect the solenoid wiring for damage from heat (proximity to exhaust) or abrasion against the transmission housing.
4
Measure resistance between the solenoid control wire and chassis ground at the PCM connector with the solenoid disconnected — low resistance indicates a wiring short.
5
Check for moisture intrusion at the solenoid connector, which is often exposed to road spray and splash.

The most common cause of P080C (Upshift/Skip Shift Solenoid Control Circuit Low) is: Skip shift solenoid with internally shorted coil windings
Typical repair costs for P080C 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 feature is non-essential and only affects fuel economy optimization. All normal transmission gear selections remain functional.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P080C to identify the root cause.
