P0962 – Pressure Control Solenoid A Control Circuit Low (OBD2)

P0962 means "Pressure Control Solenoid A Control Circuit Low". The voltage the control unit measures in the pressure control solenoid circuit is below the permitted minimum. For a sensor this usually means the signal wire is shorted to ground or the reference voltage is missing; for an actuator, that its control wire is shorted to ground.

How pressure control solenoids work

Pressure control solenoids set the hydraulic pressure that engages the gearbox clutches; these codes cover their electrical circuits and performance.

In an automatic gearbox, the clutches and brakes are applied by hydraulic pressure. Pressure control solenoids (often labelled A, B, C) in the valve body regulate main line pressure and the pressure for individual clutches. The control unit drives them with a variable current to make shifts smooth.

Codes P0745–P0749, P0775–P0779, P0795–P0799 and P0960–P0971 report circuit faults (open, low, high, electrical), performance or stuck off, stuck on and intermittent faults.

Wrong pressure causes harsh or slipping shifts and often limp mode. Besides solenoid failures, dirty fluid and worn valve bodies are common causes.

On VAG vehicles (VW, Audi, Škoda, Seat, Cupra), VCDS and older VAG testers can show this code as the five-digit VAG code 17346 (P0962). Both numbers mean the same fault.

Symptoms of P0962

  • Harsh or slipping shifts
  • Limp mode
  • Delayed engagement into Drive or Reverse
  • Check Engine or gearbox warning
  • Shift flare

Mechanic's Pro Tip

On many modern gearboxes the solenoids are only sold as part of the valve body or mechatronic unit – but specialist rebuilders often offer individual solenoids or reconditioned units at a much lower price.

  1. 1.Signal or control wire shorted to ground

    Most likely

    Look for chafed insulation where the harness touches the engine, exhaust brackets or body edges.

  2. 2.Missing 5 V reference or supply voltage

    An open reference wire or a shorted sensor elsewhere on the same reference circuit can pull it down.

  3. 3.Internal short in the pressure control solenoid

  4. 4.Faulty pressure control solenoid

  5. 5.Dirty or degraded gearbox fluid

  6. 6.Worn or sticking valve body

  7. 7.Transmission control unit fault

Step-by-step diagnostic guide

  1. 1

    Read codes and pressure data

    Read the transmission codes and, where available, commanded and actual pressures or solenoid currents.

  2. 2

    Measure the signal voltage

    With the ignition on and the pressure control solenoid plugged in, back-probe the signal wire. Then unplug it and check the reference/supply and ground wires separately.

    Multimeter: Signal near 0 V = short to ground or no reference. Reference wire: about 5 V with ignition on. Signal wire to ground with connector unplugged: no continuity.

  3. 3

    Check fluid

    Check fluid level and condition and look for debris.

  4. 4

    Measure the solenoid

    Measure the solenoid resistance through the gearbox connector.

    Multimeter: Variable force/pressure solenoids often read about 3–8 Ω; check the specification.

  5. 5

    Check line pressure

    Measure line pressure with a gauge if the gearbox has a test port.

  6. 6

    Repair and adapt

    Replace the solenoid, valve body or harness as needed, change the fluid and run the adaptations.

Frequently asked questions

Can I keep driving with P0962?

Only carefully and preferably to a workshop. Harsh or slipping shifts can damage the gearbox.

How much does it cost to fix P0962?

Typical repair costs are 100 € – 2000 €, depending on the cause and the vehicle. The most common fixes are: signal or control wire shorted to ground; missing 5 V reference or supply voltage; internal short in the pressure control solenoid. Always confirm the cause with the tests above before buying parts.

What does a pressure control solenoid do?

It regulates the hydraulic pressure that engages the clutches, so shifts are firm but smooth.

Can dirty fluid cause these codes?

Yes. Debris and degraded fluid can make the solenoids and valves stick.

What is the difference between P0962 and similar codes?

P0962 belongs to a group of codes for the same component that differ in the type or location of the fault: P0799 – Pressure Control Solenoid C Intermittent; P0960 – Pressure Control Solenoid A Control Circuit / Open; P0961 – Pressure Control Solenoid A Control Circuit Range/Performance; P0963 – Pressure Control Solenoid A Control Circuit High; P0964 – Pressure Control Solenoid B Control Circuit / Open; P0965 – Pressure Control Solenoid B Control Circuit Range/Performance. The tests on this page apply to the whole group; the type of fault tells you where to start.
