P2713

Transmission Fluid Pressure Sensor/Switch D Circuit Low

P2713 is a generic OBD-II powertrain diagnostic trouble code: Transmission Fluid Pressure Sensor/Switch D Circuit Low. It is logged by the engine control unit when the powertrain monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.

What P2713 means

P2713 is stored when the TCM or PCM detects a continuously low voltage or low pressure signal on the transmission fluid pressure sensor or switch D circuit. Unlike the intermittent code P2712, this fault is persistent: the signal remains below the minimum calibrated threshold during operation. Transmission pressure sensor D monitors hydraulic pressure in a specific clutch or valve body circuit, and its signal is used by the control module to confirm proper hydraulic operation.

A low signal can result from a short to ground on the sensor signal wire, an open in the sensor supply voltage circuit causing the signal to fall to zero, a failed sensor with an internally shorted signal output, or actual low hydraulic pressure in the monitored circuit due to a mechanical or valve body fault. The control module cannot distinguish between an electrical low and a genuine hydraulic low without additional diagnosis.

When this fault is active, the transmission control module may restrict gear selection or engage a limp mode to prevent mechanical damage from operating with unverified hydraulic pressure. Shift quality is typically affected. Both electrical and hydraulic causes must be ruled out systematically during diagnosis to avoid unnecessary component replacement.

Common causes

Most-frequently reported root causes when P2713 is logged.

  • 1
    Short to ground on the transmission fluid pressure sensor D signal wire.
  • 2
    Open circuit in the sensor supply voltage line causing the output to sit at zero.
  • 3
    Failed transmission fluid pressure sensor D with an internally shorted signal element.
  • 4
    Actual low hydraulic pressure in the monitored circuit due to a worn pump or stuck valve.
  • 5
    Corroded or damaged connector at the sensor causing a low-resistance fault to chassis.
  • 6
    Transmission valve body fault causing the monitored circuit to be depressurized.

Symptoms drivers notice

MIL and possible transmission warning light on.
Automatic transmission limp mode with limited gear availability.
Harsh, abnormal, or absent specific gear engagements.
Possible transmission overheating warning if the fault prevents cooling flow confirmation.
Reduced vehicle performance and acceleration due to transmission restriction.

How to diagnose P2713

A typical diagnostic flow when this code is present.

  1. 1
    Connect a scan tool and retrieve all DTCs; check for hydraulic, solenoid, and shift quality codes alongside P2713.
  2. 2
    Check transmission fluid level and condition as a baseline.
  3. 3
    Locate the pressure sensor D connector and inspect for damage, corrosion, or pushed-back pins.
  4. 4
    With the sensor connector unplugged, measure supply voltage to the sensor; it should be within specification.
  5. 5
    Measure the resistance on the signal wire between the sensor connector and the TCM; check for a short to ground.
  6. 6
    If wiring is intact, reconnect the sensor and monitor the signal voltage with a scan tool; a reading pinned at zero with good wiring points to a failed sensor.
  7. 7
    If the signal reads correctly with a new sensor but pressure is still low, suspect a hydraulic fault in the valve body or pump and perform a hydraulic pressure test.

Frequently asked questions

How do I know if P2713 is an electrical fault or a real hydraulic pressure problem?

Start by checking the wiring and supply voltage. If those are correct and a new sensor still shows low pressure, or if a mechanical pressure gauge confirms low pressure in that circuit, the fault is hydraulic.

Will P2713 always cause limp mode?

Many TCM calibrations will impose limp mode when a pressure sensor is reading continuously low, as the module cannot confirm safe hydraulic conditions. Some systems may allow limited operation depending on which circuit is affected.

Can contaminated transmission fluid trigger this code?

Severely contaminated or degraded fluid can cause valve body sticking, reducing actual hydraulic pressure and causing a legitimate low-pressure reading. Fluid condition should always be checked early in diagnosis.

Is the transmission pressure sensor D the same across all automatic transmissions?

No. The designation D refers to a specific circuit within a given transmission's hydraulic architecture. The physical sensor, its location, and the circuit it monitors vary by transmission model.

Disabling P2713 in software

RaceTune can permanently disable P2713 — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.

Permanent
The monitor is disabled in the ECU itself — not just cleared. It cannot return.
Tailored to your file
Each patch is matched to your specific software version — never a one-size-fits-all file.
Reversible
The original file is always preserved. Reflash the stock to return the ECU to factory state.

Software modifications affect emissions compliance and are not road-legal in many jurisdictions. RaceTune service files are intended for motorsport, off-road, and export use.
