P08BFPressure Control Solenoid L Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Points to an open control circuit of pressure control solenoid L: the module sees no load where the coil should be. No manufacturer documents this code publicly; Toyota, the only known user of letter L, has published just P08BA71. GM's open-load test for the analogous solenoid M (P08C8) shows the method: with the low-side driver switched off, the coil should pull the sense pin up to battery voltage; if the driver chip can hold it between roughly 1.7 and 3 V with a tiny current, the circuit is open. Confirmation takes 150 ms. P08C1 and P08C2 are the short to ground and short to power. Typical results are a fallback gear and the warning light.
