What Does P080B Mean?
The Upshift/Skip Shift Solenoid Control Circuit is showing a range or performance issue. The PCM is commanding the skip shift solenoid but the circuit response does not match expectations — the solenoid may be sluggish, drawing incorrect current, or not achieving the expected state within the allotted time. This is different from a simple open/short — it suggests a partially functional but degraded circuit.
Common Causes
30%
Skip shift solenoid with degraded coil resistance (partial failure)
25%
High resistance in the solenoid circuit wiring or connector
20%
Solenoid mechanically sticking or binding
15%
Low voltage supply to the solenoid circuit
10%
PCM driver circuit partially degraded
Diagnostic Steps
1
Measure skip shift solenoid resistance and compare to specification — out-of-range resistance indicates a degraded coil.
2
Monitor solenoid current draw with an amp clamp while the PCM commands the solenoid — compare to specification for expected draw.
3
Check for voltage drop across the solenoid circuit by measuring supply and ground voltage at the solenoid connector during operation.
4
Inspect the solenoid connector for corrosion or high-resistance connections that would reduce current flow.
5
Verify battery voltage is above 12.4V and the charging system is functioning properly, as low voltage can cause solenoid performance issues.
Estimated Repair Cost
$30 - $250

The most common cause of P080B (Upshift/Skip Shift Solenoid Control Circuit Range/Performance) is: Skip shift solenoid with degraded coil resistance (partial failure)
Typical repair costs for P080B range from $30 to $250, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Completely safe to drive. The skip shift solenoid is a fuel economy feature only. Normal manual shifting in all gears is unaffected.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P080B to identify the root cause.
