Drive with caution — fix soon.
This code means the engine oil temperature sensor signal is cutting in and out instead of staying steady, which usually points to a loose connection or damaged wiring rather than a fully failed sensor. The computer uses oil temperature to help manage shifting and engine protection, so an unreliable reading can cause small drivability quirks. It's typically an inexpensive fix once the bad connection or sensor is found.
$100 – $300
Varies by vehicle and root cause.
Usually yes, since the engine often runs normally. Still, an intermittent sensor tends to worsen and can cause occasional shifting or drivability issues, so get it checked before it becomes constant.
Repairs typically range from $100 to $300. Fixing a loose connector or wire is cheap, while replacing the oil temperature sensor adds parts and labor on the higher end.
It's moderate. The problem is usually electrical and not an immediate danger, but a faulty oil temperature reading can affect transmission behavior and engine protection over time.
Intermittent faults are tricky because they come and go, which makes them easy to ignore. Finding the loose connection or weak wire early prevents bigger drivability problems and a more expensive diagnosis later.
