P0749 — Pressure Control Solenoid 'A' Electrical
Drivable short-term, but fix now to avoid damage.
What P0749 means
This code indicates an electrical problem in the pressure control solenoid circuit, such as an open, short, or out-of-range resistance, rather than a purely mechanical fault. The transmission computer detects the bad signal and often limits operation to protect the unit. Typical repairs involve checking and fixing wiring and connectors, and replacing the solenoid if its internal electrical winding has failed.
Common symptoms
- Check engine light is on
- Erratic or harsh gear shifts
- Transmission stuck in limp mode
- Intermittent shifting problems
- Reduced acceleration or power
Common causes
- Open or shorted solenoid wiring
- Corroded or loose electrical connector
- Failed solenoid coil or winding
- Damaged transmission internal harness
- Faulty transmission control module circuit
Typical repair cost
$150 – $850
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0749 code?
For short distances, usually yes, but don't rely on it. An electrical fault can cause erratic shifting or limp mode at any time. Have the circuit checked promptly so a small wiring issue doesn't turn into a bigger transmission problem.
How much does it cost to fix a P0749?
If it's a wiring or connector repair, you might spend $150 to $350. If the solenoid itself has failed electrically, expect roughly $400 to $850 with labor, depending on access to the solenoid.
Is P0749 serious?
It can be, because it disrupts the computer's ability to control transmission pressure. Sometimes it's just a loose connector, but left unchecked it can lead to harsh shifting and internal wear. It's best diagnosed sooner rather than later.
How is P0749 different from P0746?
P0749 specifically points to an electrical issue in the solenoid circuit, like a short or open, while P0746 is a broader malfunction that can be mechanical or performance-related. P0749 usually starts with wiring and connector checks.
