P0803 Code: Upshift/Skip Shift Solenoid Control Circuit Malfunction
🟢 Low severity · drivable
Drivable. The skip shift feature may stop working, but the car will shift normally through all gears.
What P0803 means
On manual transmissions with skip shift (CAGS), a solenoid forces the shifter from 1st to 4th gear at light throttle to save fuel. This code means the solenoid's control circuit has an electrical fault, so the skip shift feature may stop working or get stuck.
Symptoms
- Check engine light is on
- Skip shift no longer forces 1st-to-4th at light throttle
- Shifter feels locked out of 2nd and 3rd gear
- No skip shift warning light behavior
Common causes
- most common: Faulty skip shift solenoid
- common: Damaged wiring or connector to the solenoid
- less common: Blown fuse in the circuit
- rare: Faulty powertrain control module
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Check and replace a blown fuse | Yes | $5–20 |
| Repair wiring or the solenoid connector | Yes | $50–150 |
| Replace the skip shift solenoid | Mechanic | $100–300 |
Frequently asked questions
Can I drive with a P0803 code?
Yes. The skip shift feature may stop working, but the transmission itself shifts normally through every gear.
What is skip shift?
It's a fuel-saving feature on some manual cars that blocks 2nd and 3rd gear at light throttle, forcing a 1st-to-4th shift.
How much does it cost to fix P0803?
A fuse is a few dollars. Replacing the solenoid is typically $100–$300 with labor.
