P2722 — Pressure Control Solenoid "E"

P2722 — Pressure Control Solenoid "E". A fault in the automatic transmission control. Short, gentle driving to a shop is usually possible. Typical causes: internal mechanical wear (clutches, torque converter), low or degraded transmission fluid, valve body wear.

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 P2722 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 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 P2722 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2722 (parts and labor, USD, independent shop rates): Valve body repair or replacement: $700–$1,500; Transmission fluid service: $150–$350; Transmission rebuild or replacement: $2,500–$5,500; Replace a shift solenoid: $300–$800. Overall, fixing P2722 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 P2722 mean?

Is it safe to drive with P2722?

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 P2722?

The most common causes are: internal mechanical wear (clutches, torque converter), low or degraded transmission fluid, valve body wear.

Will P2722 clear itself?

Sometimes P2722 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

How do I diagnose P2722 myself?

Start with a scan: confirm P2722, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the automatic transmission control, and verify the suspect component against live data before buying parts.

What does P2722 mean?

The engine control module sets P2722 when it detects a fault in the automatic transmission control. In practical terms: pressure control solenoid "E". The code belongs to the powertrain (engine/transmission) group of OBD2 codes.

To set P2722, the control module compares live readings of the automatic transmission control against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.

Common symptoms of P2722

Check Engine or transmission warning light on
shuddering at highway speed
harsh or delayed shifting
slipping between gears
transmission stuck in one gear (limp mode)

What causes P2722?

wiring or connector faults in the valve body harness
faulty transmission speed sensor
valve body wear
failed shift or pressure control solenoid
low or degraded transmission fluid
internal mechanical wear (clutches, torque converter)
