Can drive — fix at your convenience.
This code means the computer detected a fault in the circuit that outputs the engine's RPM signal to another device, such as a tachometer or an external module. It usually points to damaged wiring, a poor connection, or a fault in the receiving component. Repairs are generally simple wiring or connector fixes and rarely involve the engine itself.
$80 – $300
Varies by vehicle and root cause.
Yes, in nearly all cases. This code affects an output signal, not the engine's ability to run. You can drive normally, but it's still smart to have it checked so any connected gauge or device works properly.
Most repairs are inexpensive, usually $80 to $200 for wiring or connector work. If a receiving component like a tachometer needs replacing, it may reach around $300.
No, it's generally a low-severity code. It usually doesn't affect drivability, though it's worth fixing so your gauges and connected systems read correctly.
Almost never. This circuit only outputs an RPM signal to another device, so the engine itself keeps running normally. The main effect is on whatever component relies on that signal.
