P0719 — Input/Turbine Speed Sensor Circuit Intermittent
Drivable short-term, but fix now to avoid damage.
What P0719 means
This code means the signal from the input or turbine speed sensor is dropping out intermittently rather than disappearing entirely. The computer uses this sensor to time gear changes, so a flickering signal can cause erratic or harsh shifting and occasional limp mode. It's most often caused by a loose or corroded connector, chafed wiring, or a failing sensor, and is usually fixable once the intermittent fault is traced.
Common symptoms
- Check engine light is on
- Erratic or harsh shifting that comes and goes
- Transmission occasionally drops into limp mode
- Hesitation or RPM flares during shifts
- Speedometer or shift behavior glitches intermittently
Common causes
- Loose or corroded sensor connector
- Chafed or intermittently shorted wiring
- Failing input/turbine speed sensor
- Damaged or contaminated reluctor ring inside the transmission
- Transmission control module fault
Typical repair cost
$200 – $600
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0719 code?
For short trips, usually yes, but you shouldn't rely on it. Because the signal cuts in and out, the transmission can shift harshly or briefly enter limp mode without warning, which is unpredictable and stressful on the drivetrain. Get it checked soon.
How much does it cost to fix a P0719 code?
Repairs typically range from $200 to $600. A connector or wiring fix is the least expensive, while replacing the speed sensor costs more and internal reluctor ring damage requires opening the transmission, pushing the price higher. Tracing an intermittent fault adds diagnostic time.
Is a P0719 code serious?
Yes, it leans serious. The transmission depends on a steady speed signal to shift correctly, and an intermittent dropout can cause harsh shifts and surprise limp-mode events. It's wise to fix it promptly to protect the transmission.
Why is an intermittent code like P0719 harder to diagnose?
Because the fault only appears some of the time, it may not be present when the technician is testing, which makes it harder to catch. Mechanics often wiggle-test connectors and wiring or use data logging to capture the dropout, so diagnosis can take a little longer.
