Drive with caution — fix soon.
This code means the oil temperature sensor's voltage signal is lower than the normal operating range, which usually points to a short circuit to ground, a damaged wire, or a failed sensor. The most common fix is repairing the wiring or replacing the sensor. It's a common, well-understood code that's typically affordable to fix.
$100 – $300
Varies by vehicle and root cause.
Usually yes, since the engine typically still runs. However, the faulty oil temperature signal can affect shifting and engine protection, so it's best to get it checked soon.
Most repairs cost between $100 and $300. Fixing a shorted wire or connector is cheaper, while replacing the oil temperature sensor with labor lands toward the higher end.
It's moderate. The car will usually drive, but because the computer relies on accurate oil temperature for engine protection, it shouldn't be ignored long-term.
It means the sensor's electrical signal dropped below the normal range, as if the oil were impossibly cold. This usually points to a wiring short to ground or a failed sensor rather than a real temperature problem.
