P0962 on Subaru by model: symptoms, diagnosis and fix
The Ascent's TR690 high-torque CVT develops valve body faults that cause erratic shifting, harsh engagement, and transmission warning lights. The valve body controls hydraulic pressure to the CVT pulleys and chain; on these units the line pressure sensor O-ring in the valve body can leak, causing abnormal pressure readings (DTC P0841/P0842), and the transmission cannot maintain proper ratio control. This is a hardware failure rather than a calibration issue.
Common Symptoms
- Transmission warning light illuminated
- Harsh thud when shifting from Park to Drive
- CVT slipping or flaring RPMs under load
- Shuddering at highway speeds
- Vehicle going into limp mode (limited to low speeds)
- Burning fluid smell
How to Fix
Diagnose with dealer scan tool to confirm P0841/P0842 line pressure sensor faults; Subaru TSB 16-157-26 directs technicians to the enhanced P0841 diagnostic tree and supplies a redesigned valve body (31706AA164 for 2019-23, 31706AA253 for 2024-25) with an improved sensor O-ring. Valve body replacement resolves the issue in most cases — this is a less expensive repair than full CVT replacement. If the CVT has been operated with a failed valve body for an extended period, internal damage may necessitate full CVT replacement. Covered under Subaru's powertrain warranty (5yr/60k) or applicable emission warranty when in period.

Frequently asked questions
What does P0962 mean on a Subaru?
P0962 stands for "Pressure Control Solenoid "A" Control Circuit Low." This code sets when the transmission control module detects that the control circuit voltage for pressure control (line pressure) solenoid A is too low, indicating a short to ground or open in the circuit. This solenoid regulates the hydraulic line pressure that applies clutches and controls shifting, so a control-circuit fault affects shift quality and pressure. Symptoms include harsh or slipping shifts, incorrect line pressure, or the transmission entering failsafe/limp mode. The fault is usually electrical (wiring or the solenoid coil). On Subaru it is documented across 1 model: Ascent.
What are the most common causes of P0962?
The most common causes of P0962 are: Short to ground in the solenoid A control circuit, Open or high-resistance wiring or connector, Failed pressure control solenoid A (shorted/open coil), Corroded or damaged internal transmission harness, Low or contaminated transmission fluid, Internal transmission electrical fault, Faulty transmission control module (less common). The specific cause varies by vehicle.
How much does it cost to fix P0962 on a Subaru?
Published repair estimates on Subaru range from $1,500 to $8,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
