P08BE Pressure Control Solenoid L Intermittent

Drive cycleRequired
Limp modePossible

Reports a fault of pressure control solenoid L that comes and goes, typically a circuit that drops out briefly or a valve response that is only occasionally implausible. No manufacturer documents this code publicly, and in earlier packages the intermittent codes of the other pressure control solenoids also proved unused. Toyota, the one documented user of letter L, publishes only P08BA71. GM's circuit tests for the comparable solenoid M confirm a fault only after it persists for 150 ms, which is why brief dropouts tend to surface as a stored circuit code instead. CARB requires transmission solenoids to be monitored. Loose pins and chafed wires are the likely causes; symptoms are occasional shift flare or a short-lived fallback mode.

Likely causes

Loose or spread terminal at the solenoid or transmission connector
Chafed wire touching ground intermittently
Debris making the valve hang only now and then

Symptoms

  • Warning light that comes and goes
  • Occasional harsh or flaring shift
