P2720 — Pressure Control Solenoid "D" Control Circuit Low

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How to diagnose with an OBD scanner

Read the code and freeze frame Connect an OBD2 scanner, confirm P2720 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
Subsystem check Check for supply voltage at the pressure control solenoid "D" control connector first; then measure resistance from the signal wire to ground — near-zero ohms confirms a short to ground in the harness.
Subsystem check Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2720 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2720 (parts and labor, USD, independent shop rates): Transmission fluid service: $150–$350; Valve body repair or replacement: $700–$1,500; Replace a shift solenoid: $300–$800; Transmission rebuild or replacement: $2,500–$5,500. Overall, fixing P2720 usually costs between $150 and $5,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What does OBD2 code P2720 mean?

Pressure Control Solenoid "D" Control Circuit Low (P2720): a powertrain (engine/transmission) fault affecting the automatic transmission control. Short, gentle driving to a shop is usually possible. Most often caused by failed shift or pressure control solenoid, faulty transmission speed sensor, wiring or connector faults in the valve body harness.

What are the symptoms of P2720?

Drivers most often notice: no movement in severe cases, shuddering at highway speed, slipping between gears, harsh or delayed shifting.

Is it safe to drive with P2720?

Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

What is the most common cause of P2720?

The most common causes are: failed shift or pressure control solenoid, faulty transmission speed sensor, wiring or connector faults in the valve body harness.

How do I diagnose P2720 myself?

Start with a scan: confirm P2720, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the pressure control solenoid "D" control, and verify the suspect component against live data before buying parts.

What does P2720 mean?

P2720 is logged by the onboard diagnostics when the automatic transmission control does not behave as expected. The official definition is “Pressure Control Solenoid "D" Control Circuit Low”. This is a powertrain (engine/transmission) category code.

“Circuit low” means the voltage on the pressure control solenoid "D" control circuit stays below the expected minimum — close to ground. The usual physical reasons are a short to ground, a chafed wire touching metal, a missing supply voltage, or a failed component dragging the signal down.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2720 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

Common symptoms of P2720

no movement in severe cases
shuddering at highway speed
slipping between gears
harsh or delayed shifting
Check Engine or transmission warning light on
transmission stuck in one gear (limp mode)

What causes P2720?

missing supply voltage to the pressure control solenoid "D" control
failed pressure control solenoid "D" control pulling the signal low
signal wire shorted to ground (chafed insulation)
wiring or connector faults in the valve body harness
valve body wear
internal mechanical wear (clutches, torque converter)
failed shift or pressure control solenoid

How to fix P2720

Start with the cheapest and most common causes before replacing expensive parts:

Transmission fluid service — $150–$350
Valve body repair or replacement — $700–$1,500
Replace a shift solenoid — $300–$800
Transmission rebuild or replacement — $2,500–$5,500
