P08C2Pressure Control Solenoid L Control Circuit High
- 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 high, typically a short to battery voltage or to a neighbouring output. No manufacturer documents this code publicly; Toyota, the one documented user of letter L, has published only P08BA71. GM's equivalent for solenoid M (P08CB) uses two tests: with the low-side driver on, a sense voltage above 0.7 to 1.1 V, depending on supply voltage, means a short to power; at shutdown each output is also switched on in turn to detect a short to a neighbouring output, which is then stored and reported at the next start. A shorted valve usually cannot be switched off. P08C1 is the low counterpart, P08BF the open circuit.
- What you may notice
- Check engine light on
- Transmission in fallback gear
- Likely causes
- LikelyControl wire shorted to battery voltage
- PossibleShort between adjacent solenoid wires in the internal harness
- RareDefective output stage in the transmission control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €100 – €1,500
