OBD-II Generic Error Code P2719: How to Fix It

Q: Can I still drive my car with a P2719 code?

You may be able to drive short distances, but it is not recommended. P2719 indicates a fault in the pressure control circuit that regulates hydraulic pressure in your transmission. Driving with this fault can cause harsh shifting, gear slippage, or the transmission going into 'limp mode,' which limits your speed and gear selection. Continuing to drive can worsen internal transmission wear and lead to much more expensive repairs.

Q: How much does it cost to fix error code P2719?

Repair costs vary depending on what component is actually faulty. Cleaning a corroded connector might cost nothing if you do it yourself. Replacing a single pressure control solenoid typically costs $50–$150 for the part, plus $150–$400 in labor at a shop. If the entire solenoid pack needs replacement, expect $200–$500 in parts and similar labor costs. If the TCM or valve body is at fault, costs can range from $500 to over $1,500 including parts and labor.

Q: What causes code P2719 to appear?

The most common causes of P2719 are: a failed or worn Pressure Control Solenoid D; a corroded, loose, or damaged transmission wiring harness connector; chafed or broken wiring between the solenoid and the TCM; low or degraded transmission fluid affecting solenoid hydraulic function; or, less commonly, a faulty Transmission Control Module (TCM) sending incorrect signals to the solenoid.

Q: Is P2719 the same on all vehicles?

The OBD-II definition of P2719 — Pressure Control Solenoid D Control Circuit Range/Performance — is standardized across all makes and models. However, the exact location of Solenoid D, the replacement procedure, the expected resistance values, and the wiring diagram will differ between manufacturers. Always consult a vehicle-specific repair manual or database for your exact make, model, and year before beginning diagnosis or repairs.

Q: Will replacing the transmission fluid fix P2719?

If the code was triggered by low or severely degraded transmission fluid causing erratic solenoid operation, replacing or topping off the fluid may resolve it. However, if the solenoid itself has failed electrically, or if wiring is damaged, a fluid change alone will not clear the code. A fluid change is a good first diagnostic step and is inexpensive, but it should not be the only repair attempted if the fault code returns after the fluid service.

Abstract

Error code P2719 indicates that your vehicle's transmission control module (TCM) has detected a voltage or signal reading from Pressure Control Solenoid D that falls outside the expected range. This solenoid regulates hydraulic pressure inside your automatic transmission, and when it malfunctions, you may notice harsh shifting, slipping gears, or the transmission getting stuck in a single gear. Left unaddressed, P2719 can lead to further transmission damage, so it's important to diagnose and resolve it promptly.
