What P08DE means
Base code for shift solenoid L, which in SAE's lettering would be the twelfth on/off shift valve of an automatic transmission. No manufacturer documents this code publicly. It must not be confused with pressure control solenoid L, which Toyota uses on the 2024 Tacoma under its own code family. Ford's gasoline summary stops at shift solenoid E, Hyundai's Genesis 8-speed bulletin at F, and GM's 2016 to 2025 OBD tables show no L shift solenoid. For a maker using base codes, Ford's practice is the model: P0750 there means an open circuit. CARB requires shift solenoids to be monitored. The detailed fault types are P08DF to P08E6. Shift quality and gear availability may suffer.

Symptoms of P08DE
- Check engine or transmission warning light on
- Harsh or erratic shifting
- Possible substitute gear
Common causes of P08DE
- Most likelyShift solenoid L faulty
- PossibleWiring or connector fault on the solenoid circuit
- PossibleDebris in the valve body affecting the valve
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P08DE means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| DE | The exact fault in that area. |
What to do next
- Note P08DE and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P08DE
What does P08DE mean?
P08DE means "Shift Solenoid L". Base code for shift solenoid L, which in SAE's lettering would be the twelfth on/off shift valve of an automatic transmission. It is a generic code, so it means the same on every make.
Is it safe to drive with P08DE?
Drive gently and only to a workshop. With P08DE the car can go into limp mode (reduced power) to protect itself.
Will P08DE fail an emissions test?
Yes, it can. P08DE is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P08DE to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P08DE clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
