P08C0 Pressure Control Solenoid L Control Circuit Range/Performance

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

Set when the control circuit of pressure control solenoid L is electrically intact but its behaviour is implausible, for example the current through the coil does not match the commanded value. No manufacturer documents this code publicly; Toyota, the only documented user of letter L, publishes only P08BA71. As an orientation, GM's tables for the comparable solenoid M list a current check next to the circuit tests: a deviation of more than 70 % for 60 ms or more than 400 mA for 300 ms between target and estimated current, without naming P08C9 for it. Causes are a coil with changed resistance, contact resistance or supply problems. P08BF, P08C1 and P08C2 cover clear open or short faults.

Likely causes

Coil resistance out of specification
High contact resistance at connector pins
Unstable supply voltage to the transmission module

Symptoms

  • Check engine light on
  • Uneven shift quality

Repair estimate

DifficultyHardWorkshop job
Parts and labour€100–1,500
Time0.5–4 h

Typical range across vehicles; the real cost depends on what the testing finds.
