Causes

Short to ground in the solenoid control wire
Open or high-resistance wiring or connector
Corroded, loose or damaged connector terminals
Failed pressure control solenoid (coil short or open)
Low battery/charging system voltage during test
Faulty PCM/TCM driver circuit

Symptoms

Check Engine / Transmission warning lamp illuminated
Harsh, delayed or incorrect shifting
Transmission may enter limp/limitation mode
Unusual transmission line pressure or shift feel
Stored DTC P282F (and possibly related transmission codes)

What to check

Read and record all stored codes and freeze frame data with a scan tool
Verify battery and charging system voltage (13.0–14.8 V with engine running)
Visual inspection of wiring harness and connectors for damage, corrosion, pin push-out
Backprobe solenoid connector to check supply and control signals while commanding solenoid with a scan tool
Measure solenoid coil resistance at the solenoid connector (compare to spec / look for open or near-short values)
Wiggle test harness/connector while monitoring live data for intermittent faults

Signal parameters

Supply voltage to solenoid (key on, engine off): near battery voltage (~11–14 V)
Controller output: typically a switched ground or PWM signal — duty cycle 0–100% when commanded
PWM frequency: varies by vehicle; commonly 20–500 Hz (confirm vehicle spec)
Expected coil resistance: typically in the 10–40 ohm range for pressure control solenoids (refer to vehicle spec)
When commanded ON the control line will show pulsed/ground behavior; when OFF it will be open or held high

Diagnostic algorithm

Confirm P282F is current or historic; record freeze frame and any related DTCs.
Verify battery/charging voltage is good. Low system voltage can cause false low-voltage faults.
Visually inspect the solenoid connector and harness for damage, corrosion, pin damage or water intrusion.
With solenoid disconnected, measure coil resistance across the solenoid terminals. If open or shorted (out of spec), replace solenoid.
With connector disconnected, measure supply voltage at the harness connector (reference to battery ground). It should be near battery voltage with key on. If missing, trace supply/fuse/relay.
Reconnect and backprobe the control terminal at the connector. With a scan tool, command the solenoid ON/OFF and observe control signal (use a scope if available). Look for PWM or switching and verify voltage levels and duty cycle.
If control line is held low with solenoid disconnected, check for short to ground in wiring. Isolate sections of harness to locate short; repair wiring or replace damaged harness.
If wiring and solenoid check good but control signal remains abnormal, suspect PCM/TCM driver failure. Confirm with bench test or module swap where applicable before replacing module.
After repairs, clear codes, perform function tests and road test to verify proper operation and that code does not return.

Likely causes

Wiring shorted to ground at a chafe point or connector
Failed (low resistance or shorted) solenoid coil
Corroded/loose connector at solenoid or module
Open circuit in harness between module and solenoid
Intermittent poor ground or battery supply issue

Fault status

⚠️ Status

Control module reports low voltage on Pressure Control Solenoid K control circuit (P282F). Possible causes include wiring short, connector corrosion, failed solenoid coil, or module driver fault. Inspect wiring, test solenoid and verify control signals.
