P08BBPressure Control Solenoid L Performance/Stuck Off
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Set when pressure control solenoid L is commanded but the pressure or shift element it serves does not respond, i.e. the valve acts as if it were stuck in its off state. No manufacturer documents this code publicly. Toyota, the only known user of letter L, reports a stuck valve as P08BA with suffix 71 instead. The closest documented analogue is GM's P08C4 for solenoid M on the Corvette dual clutch, where an intrusive routine moves the shift rods slightly and flags the valve when the expected rod travel stays below 100 µm. CARB requires such functional checks for transmission solenoids. P08BC is the opposite fault, P08BF to P08C2 cover the circuit. The driver notices missing or harsh shifts.
- What you may notice
- Check engine light on
- Missing, slipping or delayed shifts
- Possible substitute gear operation
- Likely causes
- LikelyValve spool held closed by debris or varnish
- PossibleLow fluid level or weak supply pressure to the valve
- PossibleLeaking seal or circuit downstream of the valve
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
