Drivable short-term, but fix now to avoid damage.
This code means the computer expected an engine speed signal from the ignition or distributor sensor but received nothing at all. It typically points to a completely failed sensor, a broken wire, or a disconnected connector. The repair usually involves replacing the sensor or distributor pickup and repairing the open circuit in the wiring.
$150 – $500
Varies by vehicle and root cause.
No, you really shouldn't. With no engine speed signal, the car often won't start or will stall unexpectedly. Get it towed or repaired right away rather than risk being stranded.
Expect roughly $150 to $500. A failed sensor is cheaper to replace, but distributor replacement or extensive wiring repair raises the cost.
Yes. It usually means the engine has lost a critical signal and may not run at all. It needs prompt attention to get the vehicle reliably starting and running again.
The computer uses the RPM signal to control spark and fuel timing. With no signal at all, it can't fire the engine properly, so the car often cranks but won't start.
