P08C1Pressure Control Solenoid L Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Reports a control circuit voltage of pressure control solenoid L that is too low, usually a short to ground. No manufacturer documents this code publicly; Toyota, the one documented user of letter L, has published only P08BA71. GM's equivalent for solenoid M (P08CA) illustrates the check: while the low-side driver is switched on, the sense pin is examined and a value below about 1.7 V is read as a short to ground, confirmed after 150 ms with battery voltage between 8.75 and 18 V. Depending on the wiring, a ground short can energise the valve permanently or make it uncontrollable. P08C2 is the high counterpart, P08BF the open circuit. Expect a fallback gear and the warning light.
