Pressure Control Solenoid 'D' Control Circuit Range/Performance Problem
There's an issue with the pressure control solenoid circuit or its performance.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The transmission control module is seeing that the pressure control solenoid 'D' isn't behaving as it should, which affects how your transmission shifts.
What the computer is actually seeing
The TCM expects a specific voltage range for the pressure control solenoid 'D'. When it commands the solenoid to activate, it should see around 12V-14V when energized. If it sees less than 5V or greater than 15V, it triggers this code.
What a healthy reading looks like
When testing the circuit, expect the solenoid to pull around 0.5A to 2A when engaged; voltage should be between 12V-14V as mentioned.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the transmission fluid level; it should be within the specified range. If it's low, top it up and retest.
- 2Inspect the wiring and connectors related to the pressure control solenoid 'D' for damage or corrosion, repair as needed.
- 3Test the voltage at the solenoid connector while operating the vehicle; should be 12V-14V with the solenoid activated. If no voltage is present, check for wiring issues back to the transmission control module (TCM).
- 4If voltage is correct, use a multimeter to check resistance of the solenoid itself; it should be within specifications. Replace if out of range.
- 5After repairs, clear the codes and take the vehicle for a test drive to monitor for reoccurrence.
Common causes
- Faulty pressure control solenoid 'D'
- Wiring issues in the solenoid circuit
- Bad connector or electrical connection
- Transmission fluid contamination
- Low transmission fluid level
Typical repair cost
$$$
