P282E Pressure Control Solenoid K Control Circuit Range/Performance

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

P282E is meant for a solenoid K control circuit whose behaviour strays from what the TCM expects although there is no clean open or short. No manufacturer documents it publicly, and CARB 13 CCR 1968.2 states the monitoring duty only in general form. GM's K valve in the 2023 Corvette illustrates what such a check could look like: the TCM derives valve current from duty cycle and supply voltage and compares it with the request, yet a miss of more than 70 % for 60 ms or 400 mA for 300 ms is stored as P2830, not as P282E. Coil resistance rising with heat, a poor ground or a weak driver stage are the likely technical causes. Measure resistance cold and warm and compare actual and requested current in live data.

Likely causes

Coil resistance rising with temperature
Poor ground or supply to the driver stage
Weak output stage in the TCM

Symptoms

  • Uneven gear preselection
  • MIL or transmission warning
